9v accumulator & charger combo tips

[unclefu]

Hi everyone!

I tried various 9v accumulators with my charger, but after like 5-10 charges, they all stopped working. It's probably because of my charger, but I know the accumulator itself can also mess up things. So my question is, anyone knows any accumulator-charger combinations that worked for them without problems like this, and what are they? And for how long? It probably doesn't matter, but I'm using it for a wireless system.

Thanks in advance!

Anyone with any tips? Just a brand and type of the battery and the charger that works well would mean a lot! Sorry for the bump.
