Hello,
I use NiMH rechargeables for many devices from MP3 player to flashlights since 1 year and I noticed something when charging batteries. I often test the batteries voltage with a multimeter after charging and I noticed that the final voltage of batteries incrased after many charge cycles. At beginning, with Duracell 1800mAh it was 1.43V and now it's around 1.48V. Same thing is happening with Energizer 2500mAh. Around 1.4V at the beginning and I have now 1 battery I test around 1.45V after charging. Is it related to internal resistance decreasing?
