Description
Panasonic NCR18650GA 3450 mAh Battery – Protected Button Top
High-Capacity, Long-Life Power for Demanding Devices
Experience outstanding performance with the Panasonic NCR18650GA, a high-capacity 3450 mAh lithium-ion cell engineered for applications where reliability and endurance matter. Designed to provide strong discharge capability, this protected button-top 18650 is ideal for high-drain devices such as portable power tools, e-bikes, high-output flashlights, and other energy-intensive electronics.
With its elevated energy density and robust protection circuit built in, it gives you the power and durability you need in demanding environments.
Note: This is a button-top, protected version of the 18650 battery, which is slightly longer than standard flat-top unprotected cells.
Key Features:
-
High Capacity: 3450 mAh nominal capacity means longer usage cycles between charges — great for users who need extended runtime.
-
Strong Discharge Rating: Designed for continuous discharge of up to 10 A (PCB limit may restrict to 6 A in many applications) — supports high-drain applications with ease.
-
Protected Button Top: Built-in protection circuit (PCB) guards against over-charge, over-discharge, and short-circuit conditions — adding safety on top of performance.
-
Wide Compatibility: Standard 18650 form factor (approx. 18.5 mm × 69.5 mm for this protected version) — fits many existing 18650 devices designed for protected button-tops.
-
Elevated Energy Density: More stored energy per volume/weight means fewer swaps or recharges required.
-
Durable Build: Quality manufacturing from the established brand ensures consistent performance and longevity under typical use conditions.

⚠ Important Safety Warnings
While this battery includes a protection circuit, improper handling or misuse can still result in fire, explosion, or thermal runaway. Before use, read and follow all safety guidelines:
-
Intended Use: Designed for use in devices compatible with protected, button-top 18650 cells. Always ensure compatibility with your equipment.
-
Limitations of Protection Circuit: The built-in circuit helps guard against certain failure modes, but it cannot protect against misuse such as physical damage, exposure to liquids, or extreme heat.
-
Handling & Storage: Store in proper non-conductive cases; avoid loose storage with metal objects (e.g., keys, coins). Do not store in uncontrolled environments like pockets or bags containing metal items.
-
Inspection: Do not use the battery if it is dented, leaking, bulging, or if the outer wrapper or button top is damaged.
-
Charging: Use a charger specifically rated for lithium-ion protected 18650 cells. Do not exceed the cell’s specified voltage (4.2 V) or current. Never leave a charging cell unattended.
-
Prohibited Activities: Do not expose the battery to water, fire, high heat, or attempt to modify, puncture, crush, or disassemble it. If the battery overheats, emits smoke, or shows signs of failure, stop use immediately, move it to a non-flammable surface, and follow emergency safety protocols.
