I just got the nitecore d2 charger which I use to charge my 2 efest 2500 mah 18650 batteries. One battery is about 2 months old and the other is 2 weeks old. I use an ipv2 (usb port broke), along with the aspire atlantis.
I noticed when I charge them fully to 4.20 v the battery doesn't as last long as it did when I was just using the USB port on the ipv2. I would go a full day without having to charge, and now my battery life is about 4 hours. The battery life decreased a lot for both batteries.
Is there something wrong with the charger, or batteries? I got the 2nd efest when I bought the nitecore. Please help!
