Seeing this is a Battery thread, I think I should post here...
I had no clue that Ni-MH have a a useful life of only 5 Years....working or not.
I know that SLA have problems. Ni-MH...I never heard about problems before. Till today....
So, luckily when I started my project, I only purchased around 10 of them....that was in 2010....Some have worked hard and cycled daily, some have just sat on a shelf...
Tested today after all being fully recharged ...they all have the same reduced capacity. Cycles do not matter....age does.
Little PP3's. I have learned....I almost bought 100 of them a few years back at an excellent price....
I would have cried today.
