Hello all,
I have 2 generic brand UPS's and after a few years they have both failed to support my pc's even though I change the batteries every 2 years.
They worked very well for my requirements. I measured the voltage on the battery (the block type 12v 7a) and it is about 13.3v.
I have taken apart one UPS as I read somewhere that cheaper brand UPS often kill the batteries by over-charging them to quickly but there are no pots on the board to adjust any voltages.
Here is what the board looks like.

I am wondering if it is worth changing any of the parts to save these instead of buying new ones?
