One of these Batteries had a problem February 4, 2019
Reviewer: Thomas Fisher from Seadrift, TX United States  
One Battery was good and one had to be refreshed two times to take a charge. I am using it now to see if it will hold a charge.

Charger indicates poor January 5, 2019
Reviewer: Aris Matevosian from Glendale, CA United States  
I was very eager to receive these batteries, but once I put them to change in my SC4 charger 6 out of the  8 batteries indicated as poor condition. I hope it's not the batteries.
