SAMSUNG SDI · 21700 · CC5493F101 (Ver. A)
A 21700 lithium-ion cell: 5,330 mAh standard minimum capacity at 0.2C, 5,170 mAh rated minimum at 1C, and a maximum discharge current of “2C (for continuous discharge)”, which is 10,660 mA at the printed 1C of 5,330 mA (2 × 5,330 mA, our arithmetic) [1]. Samsung SDI’s specification identifies the cell as model CC5493F101 (Ver. A); the name 58E is printed in neither of the two versions we hold, Draft V0.1 [1] and the earlier V0.0 [2]. Samsung SDI marks both confidential and [1] is a draft, so we quote them here but don’t link them (section 13). Below: every rating with its condition, the figures Samsung SDI prints in its tables, and what we calculated from them, so you can check each number.

Every rating, with its condition.
Samsung SDI’s data sheet for this cell is titled Specification of Product [1]; this page calls it the specification. The newest we hold is Draft V0.1, from 2023. It is marked “Draft”, and its cover says the official version is valid only with separate written confirmation by Samsung SDI. Its ratings come first, copied as printed. Then the capacity figures its tables print, our arithmetic, and the documents we hold. Each row names its source or shows its formula.

Bars start at zero. [1] prints a typical energy and no typical capacity in mAh. The second bar is our arithmetic, 3.64 V × 5,330 mAh = 19.4 Wh: an estimate at the minimum capacity, not a rated minimum. It agrees with the “(19.4Wh)” the earlier V0.0 printed beside its minimum [2].

Printed C-rates, in mA
[1] prints each current for the cell as a C-rate and defines “*1C=5,330 mA”; the other mA are our arithmetic, C-rate × 5,330 mA. Orange: 2C, the continuous maximum. 3C, “not for continuous discharge”, is left out. V0.0 printed mA beside most of these: two truncated (106 and 266 mA) and “2C (11,200mA)”, which doesn’t match (section 07).
02 · CAPACITY
95 % of 5,330 mAh at 2C.
Samsung SDI’s specification prints the capacity at three currents in [1] §7.6, 0.2C, 1C and 2C, as a percent of the 5,330 mAh standard capacity. At 2C, the continuous maximum, it prints 95 %: about 5,064 mAh. By our arithmetic, 2C is 2 × 5,330 mA = 10,660 mA, and 5,064 mAh lasts about 28.5 minutes at that current.

Capacity and runtime, by current.
[1] §7.6 prints the capacity at 0.2C, 1C and 2C as a percent of the 5,330 mAh standard capacity, and prints no currents in mA. The mA, the mAh and the runtime are arithmetic on those figures, with the formula under each.

Capacity to 2.50 V at each current, after Standard charge at 23 °C, printed in [1] §7.6 as a percent of the 5,330 mAh standard capacity; mAh = percent × 5,330, rounded half up; mA = C-rate × the 5,330 mA that [1] defines as 1C. The 1C row matches the 5,170 mAh rated minimum [1]. Orange: 2C, the continuous maximum.

CALCULATED FROM [1]FIG 3.2
Runtime at a constant current
Runtime = capacity ÷ current, from the mAh and mA in fig 3.1: one full Standard charge, constant current to 2.50 V at 23 °C. A device whose average draw is below its peak current runs longer than the figure at that peak.
2C, and what it means in amps
- [1] rates 2C “for continuous discharge” and defines “*1C=5,330 mA”. 2 × 5,330 mA = 10,660 mA (10.66 A): our arithmetic. [1] prints no mA or A figure for 2C, and no document prints 10,660 mA; the earlier V0.0 printed “2C (11,200mA)”, which doesn’t match its own 1C (last item).
- Note (*²) adds: “Max. discharge current condition does not guarantee the cycle life.” The cycle-life rating discharges at 1C (section 06 below); [1] gives no cycle-life figure at 2C.
- [1] gives the discharge temperature as −10 to 60 °C “(Ambient)”. Note (*³) asks for a pack’s discharge over-temperature protection to be set no higher than 70 °C at the hottest cell surface [1]. The 2C line itself carries no duration and no cell-temperature cut.
- [1] also lists 3C under Max. Discharge Current, marked “not for continuous discharge”, with no duration or condition. We publish continuous ratings only, so we leave it out.
- The earlier V0.0 printed “2C (11,200mA)” in its rate table, which doesn’t match its own 1C of 5,330 mA (2 × 5,330 mA = 10,660 mA); Draft V0.1 prints no mA there (section 07 below).
04TEMPERATURE
Capacity in the cold and the heat.
One table in [1] §7.5: capacity when a 1C discharge runs at −10, 23 and 40 °C, after a Standard charge at 23 °C. −10 °C is the bottom of the discharge range in [1]; there, [1] prints 50 %. [1] prints no table for charging at other temperatures.
CALCULATED FROM [1]FIG 4.1
Capacity, by discharge temperature
Capacity when the discharge runs at each temperature: 1C (5,330 mA, as [1] defines it) to 2.50 V after Standard charge at 23 °C; where the temperatures differ, [1] sets a 3-hour interval for the temperature change. Printed in [1] §7.5 as a percent of 5,330 mAh; mAh calculated. Orange: −10 °C, the bottom of the discharge range in [1] §3.15, “(Ambient)”.
CALCULATED FROM [1]FIG 4.2
Runtime at 1C, by temperature
Runtime = capacity ÷ 5,330 mA, from fig 4.1. At −10 °C the same discharge ends after about 30.0 min, against 58.2 min at 23 °C: arithmetic on [1] §7.5. Below −10 °C is outside the discharge range in [1].
PRINTED · [1][2]FIG 4.3
Capacity at −10 °C, by version
Draft V0.1 [1]V0.0 [2], superseded
Capacity at −10 °C, 1C, after Standard charge at 23 °C, as each version prints it in its §7.5, as a percent of the standard capacity: 50 % in Draft V0.1, 70 % in V0.0. Both print 97 % at 23 and 40 °C. [1] doesn’t say why the figure changed; this page follows [1].
05CHARGING
Charging: 0.5C standard, 1C maximum.
The specification rates a 0.5C standard charge, CC-CV to 4.2 V with a 0.02C cut-off, “Standard charge: 4 hours”, and a 1C maximum that is “not for cycle life”. At the printed 1C of 5,330 mA, those are 2,665 and 5,330 mA by our arithmetic. Its cycle-life rating charges at 0.5C. Charge between 0 and 45 °C ambient [1].

Voltage thresholds for a pack’s battery management system (BMS): the cell ratings in [1], and the pre-charge, re-charge and do-not-charge levels from the pack design guideline printed in [1]. Orange: the working range. The re-charge mark sits at 4.1 V, the highest the guideline allows. Below 1.0 V, the guideline says not to charge the cell at all.

Where [1] allows charging: 0 to 45 °C ambient [1] §3.15, the same range its pack design guideline prints; orange: the §3.15 range. [1] prints no capacity after a charge at any other temperature, and no cell-surface charge limit. Below 0 °C, don’t charge.
Before you charge
- Use a lithium-ion charger with a CC-CV profile that stops at 4.2 V.
- 0.5C, 2,665 mA by our arithmetic (0.5 × 5,330 mA), is the standard charge and the charge for cycle life. 1C, 5,330 mA, is the most [1] allows, and it marks that rate “not for cycle life”: the 500-cycle rating uses a 0.5C charge, and [1] prints no charge time and no cycle-life figure at 1C.
- Charge only between 0 and 45 °C ambient [1]. Below 0 °C, don’t charge.
- Don’t charge a cell that has fallen below 1.0 V; the pack guideline in [1] says not to.
- In a pack, a BMS (battery management system) should end charge at 4.2 V per cell; the pack guideline asks the charger to stop on charging time or current [1].
Fig 5.1 plots values that the pack design guideline in [1] prints as text; Samsung SDI draws no chart of them. The guideline matches the cell ratings: charge cut-off “must be 4.2V”, discharge cut-off “must be over 2.5V” [1]. [1] prints no charge-rate table and no charge-temperature table, so this section has no capacity-by-charge figure.
06CYCLE LIFE AND STORAGE
What it keeps after use and storage.
[1] rates at least 4,136 mAh after 500 cycles, and at least 4,797 mAh after 20 days at 60 °C. It prints no cycle-life curve, so these are the two points on the page. It also prints three storage statements, each worded differently.
RATED · [1]FIG 6.1
Capacity after storage and cycling
Minimum capacity as rated in [1]. New and after 20 days at 60 °C: 0.2C to 2.50 V at room temperature. After 500 cycles of 0.5C charge (CCCV, 0.05C cut-off) and 1C discharge to 2.50 V at room temperature: 80 % of the 5,170 mAh rated capacity. Orange: the cycle-life floor. A rating, not a warranty, and not a curve: [1] prints no capacity between cycle 1 and 500.
PRINTED IN [1]FIG 6.2
Storage, three statements in [1]
Recovery table, [1] §3.16 “1 year -20~23℃” · more than 80 % recovery, kept at the ex-factory 30 % charge
Handling section, [1] Proper Use 3.1.1 “0 ~ 23℃, low humidity (below 65%)”
Pack design guideline, [1] 1.3 “below 60℃, 20℃ is recommended”
The three storage statements in [1], each in its own words; [1] doesn’t reconcile them. Marks on the last row: 20 and 60 °C. All three are met at 0 to 23 °C, dry (our reading). For 3 months or more, [1] §10.1 recommends dry, low-temperature storage; its handling section says to store cells at the shipping voltage, 3.54–3.64 V [1] §7.9.
07WHAT CHANGED
The V0.0 and Draft V0.1 specifications, side by side.
The earlier V0.0 [2] printed some figures that Draft V0.1 [1] does not: a typical capacity in mAh, a minimum energy, and mA beside the C-rates in its test conditions and rate table (not in the ratings). [1] drops those, adds a 0.5C charge for cycle life, tightens the initial impedance from ≤ 18 to ≤ 15 mΩ, lowers the printed capacity at −10 °C from 70 % to 50 %, and widens the shipping-voltage range. [1] doesn’t say why. Every rating on this page follows [1], the newer document.

Where the 58E sits.
Twelve other 21700 cells, each from its own data sheet. Of the twelve, only the M65A prints a higher minimum capacity (6,400 mAh, on a preliminary sheet). Only the 50E prints a lower highest continuous figure (9.8 A); the 50G and M50LT print lower continuous figures in part of their temperature ranges (9.8 A at 31 to 60 °C; 7.2 A at 25 to 55 °C and 2.4 A at −20 to 10 °C). A higher discharge rating usually costs capacity. The conditions behind each rating differ, so the table quotes each sheet’s wording.

Each cell’s figures copied from its own data sheet [1][3]. Bars start at zero: minimum capacity on a 0–7,000 mAh scale, discharge on 0–60 A. The condition sits beside each current; where a sheet prints more than one continuous figure, the bar shows the highest and the condition names another. The 58E’s 10.66 A is our arithmetic, 2 × 5,330 mA; [1] prints the rating as 2C. The M65A sheet is preliminary R&D data. Pulse and other non-continuous figures are left out.

CALCULATED FROM [1]FIG 9.1
Continuous current ceiling, by parallel count
10.66 A × P: the single-cell 2C rating at the printed 1C of 5,330 mA [1], times the parallel count; our arithmetic. A ceiling before derating, not a pack rating.
* 10.66 A × P is our arithmetic: “2C (for continuous discharge)” at “*1C=5,330 mA” [1], times the number of cells in parallel; [1] prints no amp figure. Wh = 3.64 V × 5.33 Ah × S × P, an estimate at the minimum standard capacity. [1] gives discharge temperatures of −10 to 60 °C ambient and asks for discharge over-temperature protection at no more than 70 °C on the hottest cell surface, Note (*³); Note (*²) says the maximum discharge current “does not guarantee the cycle life”. Derate for heat, size the BMS, fusing and interconnects for the derated current, and use matched cells of one model and lot; [1] recommends more than 1 mm between cells and a second protective device such as a PTC or PCM. Mass counts cells only. A pack you build needs its own UN38.3 testing before it ships, and we hold no UN38.3 test report for the cell itself (section 01).

11USE IT RIGHT
Keep it inside its ratings.
What this cell is, and how to use it within its ratings.
- This is a bare cell: a component for protected packs and devices built for it. It is not a standalone consumer battery and not for vaping.
- Unprotected. [1] doesn’t state the top style: check that your device takes a cell 71.00 mm long and 21.78 mm across, the maximums in [1].
- Charge on a lithium-ion (Li-ion) charger that stops at 4.2 V. Stop discharging at 2.5 V [1].
- Stay inside the ratings [1]: discharge at no more than 2C continuous (10,660 mA: 2 × 5,330 mA, our arithmetic), between −10 and 60 °C ambient; charge at 0.5C standard (1C at most, “not for cycle life”), between 0 and 45 °C ambient.
- Replace a torn wrap before use. Carry cells in a case, never loose.
- For packs: matched cells of one model and lot, a BMS, a second protective device such as a PTC or PCM, more than 1 mm between cells, and a place away from heat sources [1]; add fusing sized for the pack.

12QUESTIONS
Questions, answered.
Short answers. Where an answer comes from a document, it carries its source; the rest is standard handling practice. Anything else: call 1-800-547-3050 or text 1-833-419-2192.
Is the 58E a protected cell?
No. It is a bare cell with no protection circuit. Use it only in packs with a battery management system (BMS) or in devices built for unprotected cells. [1] doesn’t state the top style.
Does the specification say 58E?
No. Neither Samsung SDI document we hold prints the name 58E; both identify the cell as SDI Model “CC5493F101 (Ver. A)” [1][2]. 58E is the name we list it under. Every 58E rating on this page comes from the CC5493F101 specification; results from our own lot are not shown (section 13).
Is it a 5,330 mAh cell?
Yes, as a minimum. [1] rates “Min. 5,330 mAh” at 0.2C to 2.50 V (the standard capacity) and 5,170 mAh minimum at 1C (the rated capacity). Draft V0.1 prints no typical capacity in mAh, only a typical energy, “(Typ. 20.0 Wh)”. The earlier V0.0 printed a typical mAh that V0.1 dropped (section 07 below). The name 58E is not a rating; use the printed figures. Every capacity on this page follows [1].
What is “2C (for continuous discharge)” in amps?
10.66 A, by our arithmetic. [1] states its currents as C-rates, multiples of a reference current it sets at “*1C=5,330 mA”, so 2C is 2 × 5,330 mA = 10,660 mA (10.66 A). [1] prints the rating only as “2C (for continuous discharge)”, with no duration or cell-temperature condition on that line. Its temperature conditions are the −10 to 60 °C ambient discharge range and Note (*³): a pack’s discharge over-temperature protection set no higher than 70 °C on the hottest cell surface. Note (*²) says the maximum discharge current “does not guarantee the cycle life”; the 500-cycle rating discharges at 1C. Its handling section says the cell “shall be discharged continuously at less than maximum discharge current”. At 2C, [1] §7.6 prints 95 % of the standard capacity, about 5,064 mAh. In a pack, plan for less than 10.66 A per cell.
Why might other listings show a different current?
[1] lists a second figure under Max. Discharge Current, 3C, marked “not for continuous discharge”, with no duration or condition. A listing that repeats it is quoting a non-continuous maximum with no duration or condition printed; we don’t list it. The earlier V0.0 also printed “2C (11,200mA)” in its rate table, which doesn’t match its own 1C of 5,330 mA (2 × 5,330 mA = 10,660 mA); Draft V0.1 prints no mA there. A figure of 10.7 A is 10.66 A rounded. 2C, 10,660 mA by our arithmetic, is the continuous rating, so it is the discharge figure we publish.
How fast can I charge it?
Standard is 0.5C, 2,665 mA by our arithmetic (0.5 × 5,330 mA): CC-CV to 4.2 V with a 0.02C cut-off, “Standard charge: 4 hours” [1]. The most [1] allows is 1C, 5,330 mA, marked “not for cycle life”: the 500-cycle rating uses a 0.5C charge, and [1] gives no cycle-life figure or charge time at 1C. Charge between 0 and 45 °C ambient [1].
What charger should I use?
A lithium-ion charger with a CC-CV profile (constant current, then constant voltage) that stops at 4.2 V. Not a NiMH, LiFePO4 or lead-acid charger.
How long will it run at my current?
Runtime ≈ capacity ÷ current. Calculated from the capacities in [1] §7.6, after a full Standard charge at 23 °C: about 5 h 00 min at 0.2C (1,066 mA), 58.2 min at 1C (5,330 mA) and 28.5 min at 2C, 10,660 mA (fig 3.2); the mA are C-rate × 5,330 mA. For your own draw, divide 5,330 mAh by your current in mA to get hours. Expect a little less at higher currents (fig 3.1) and about half at −10 °C (fig 4.1).
How does cold affect it?
At −10 °C, the coldest discharge temperature in [1], its table in §7.5 prints 50 % of the standard capacity at 1C, about 2,665 mAh, against 97 % at 23 °C. The earlier V0.0 printed 70 % there (fig 4.3). [1] prints no capacity after a cold charge; don’t charge below 0 °C.
How many cycles will it last?
The specification rates at least 4,136 mAh, 80 % of the rated capacity, after 500 cycles of 0.5C charge (CCCV, 0.05C cut-off) and 1C discharge to 2.50 V at room temperature [1]. It gives no figure for other currents or temperatures, and no end-of-life count; Note (*²) says the maximum discharge current “does not guarantee the cycle life”. Heat, current, depth of discharge and storage all change the result.
Is there an SDS or a UN38.3 test report?
Not on file. We hold no safety data sheet (SDS) and no UN38.3 test report for this cell. Its specification lists only “UN38.3” under safety, in [1] §8, with no report number, test list, results or date, so this page makes no transport claim based on a report. We can’t supply a UN38.3 test summary or an SDS for this cell; if you need either to ship cells or packs, call or text before you order.
Can I use it in a vape or e-cigarette?
No. It is a bare cell: a component for protected packs and devices built for it, not for vaping. Samsung SDI’s specification says its cells “are not designed or manufactured for use in any vape or e-cigarette devices” [1] (handling precaution 3.6.1).
Can I solder to it?
Don’t solder directly to the cell: the heat can damage the seal and internal parts. Spot-weld nickel strip, or use a holder.
Can I mix 58E cells with other cells?
No, not in the same pack. Use cells of the same model and lot, at the same state of charge; [1] also says “Don't use or assemble old and new batteries together.” In series, the weakest cell reaches 2.5 V first and limits the whole pack, and mismatched cells drift further apart with every cycle.
How should I store spare cells?
In a case, away from metal objects, somewhere dry and cool. [1] prints three storage statements, each worded differently: its handling section says to store cells at “0 ~ 23℃, low humidity (below 65%)”; its pack design guideline says “below 60℃, 20℃ is recommended”; and its recovery table rates more than 80 % recovery after 1 year at −20 to 23 °C, for a cell kept at the ex-factory 30 % charge (fig 1.4). Storage at 0 to 23 °C, below 65 % humidity, meets all three (our reading). For long-term storage, it says to keep cells at the shipping voltage, 3.54–3.64 V. Check the voltage every few months.

- + Method: the specifications [1][2] print two relative-capacity tables, not performance charts, and none of the documents we hold has a curve for this cell. Every chart on this page plots a figure printed in [1], [2] or [3], or arithmetic on those figures with the formula under it; where a line joins printed points, nothing between them is printed. [1] prints its currents as C-rates: every mA or A figure for this cell, other than those quoted from [2], is the C-rate × the printed 1C of 5,330 mA. mAh from a printed percent = percent × 5,330 mAh, rounded half up. Each figure was copied from the document and checked against it by a second reading.
- + Not shown from [1]: its 3C discharge figure, printed “not for continuous discharge” with no duration or condition, because we publish continuous ratings only; the rest of its vape and e-cigarette warning (handling precautions 3.6.2–3.6.5), which also addresses handling by individual consumers (3.6.3) and online e-commerce and consumer sales (3.6.5); its warranty clause, which applies to Samsung SDI’s direct customers; and its packaging drawings and bill of materials.
- + Not shown: results from our own lot. We will add them only once our incoming-inspection procedure is published, with sample size, instrument and date.

Overall rating: 4.9 / 5 from 87 reviews.
Product worked as expected. If ordering from Canada, beware of surprise import duties collected by FedEx: $70CAD on $300CAD order (ordered 2026-06-17).
Packaged very well, arrived as expected. Excellent value.
Same price as 18650, it was a better choice for me.
Fast shipping. Accurate product. Good prices.
I like this company, reliable and fast. But to be honest the battery capacity is about 4600mAh. Measured it twice
Quick shipping!
Most reasonable prices I could find — stellar products — recommend 100%
I was very upset when they didn’t come in the plastic battery holders like the other several orders I made
I stalked and working well on leaf blower.
I cycled them twice at 1A and down to 3.0v, most were 5000mah
I was able to built for 48v in 13s4p on my ebike.
Batteries shipped quickly and arrived on time
On time, no issues
I ordered wrong battery thought I was getting 18650 my bad. Have not used may not have A project that I can use them in.
now all my flashlights have new batteries that stay charged a long time
Good job! Need more deals. Thanks.
I enjoyed the easy ordering process. The batteries arrived quickly and by appearance in good shape. I look forward to using them in the project I bought them for.
Great prices, fast shipping, and quality cells just as shown. Also came with complementary storage boxes. Will buy from here again. Thanks!
Working great. Has some charge in them right out of the box. Put them in my Astrolux ST02 flashlights. Still hasn't charged them after 7 months of light usage. The plastic storage box they came in is a nice touch.
Good prices on first quality products. I’ll return to buy more when the time comes. Thanks again
great batteries for a great price.
Good packaging, fast shipping. Have yet to fully test.
Great service, Quick shipping. All 21700 batteries were equal in charge state when received and in good condition. Worked perfectly for my 10s8p pack project!
They came just like their website said.
All good except the positive post is pretty small. May be hard to get 3 welds.
My first batch of 20 cells after a few Cycles ended up getting 5,200ish milliamps of capacity. Few months later I purchased 20 more and so far after 5 cycles I'm still at 3,200 milliamps of capacity. They might come up but we're a long way to their stated capacity.
👍
High quality and fast delivery
Great website for buying cells to use in projects! Internal resistance on all cells was perfect, and the cells arrived unharmed and as described in their listing.
Bought these to power camping flashlights. They do the trick and power led lights and lanterns for days!
