I saw similar good bat. condition on LEDS on my APC, But, looking at a battery's voltage only tells one the charge state. If it's charged, but old & acquired a high internal resistance, the only way to know is to use it to feed a load. I use old car headlamp batteries to test my 12V batteries (usually one of 2 filaments dies, out of dipped & main beam, & the other is still usable). Put as many as possible in parallel to suck power. Of course that's an off line dismantled test, after the teeth gnashing & "why on earth did it fail?" taking out of service ;-). -- Julian Stacey.
