I am not sure if it chalks up to stupidity of the consumer in the US or what but really I think it's the chargers and the cells are fine, though someone with more money than me would have to do a test to see if a charger really does make a difference. Aka someone buys a cheap Duracell charger and batteries and uses it together as the package says and then buys a pack of the same Duracell cells and uses them in a good charger. Though I am not even sure if such a test is necessary as we all know what would likely happen.
I bought a Lenmar R2G charger that came with 4 Lenmar R2G AA batteries plus two more packs of 8 additional batteries.
The first thing I did was try 4 of those batteries in a 2 port sprinkler timer. They worked for a few days, then got drained completely. I then tried to charge them in the Lenmar charger and it blinked red indicating that all 4 batteries had gone bad. I happen to have a Tenergy 4 port LiPO/PB/NiMH battery charger for my RC helicopters, so I decided to make a plastic tube so I could put all 4 batteries in series and try charging them on the NiMH setting. They charged with no problem and are working fine and now charge fine in the Lenmar charger. This basically means that the Lenmar charger is crap and won't charge dead NiMH batteries that are perfectly fine. Had I not had the Tenergy charger and some persistence I probably would have believed the Lenmar charger and thrown them away.
I've since bought a much better sprinkler timer, but these batteries still don't work in it, so I'm stuck with the only application of these batteries being one of my remotes. They work great, but all my other devices require LiPOs.
