Review on Tenergy Centura 1.2V NiMH Rechargeable D Battery, 8000mAh LSD D Cell Batteries, Pre-Charged D Size Battery, 4 Pack - UL Certified by Michelle Rogers

Great batteries and have been using them a lot for many months. There seems to be an issue with the charger that reads some batteries just as badly when you try to charge them once they're dead. I found that when my charger indicated the battery was low, I had to leave them overnight before attempting to charge them. I have several chargers and all of them had this problem. By simply leaving them overnight, I was able to charge them normally the next day. Aside from that weird "bad battery" when it's just about dead, they work great.
