Question : Problem: Trouble-shoot UPS not working

Hi Experts.  I have a Compaq T2000 UPS that I received from an idiot colleague and after updating the outlet to match the plug head, I found out that the unit won't power on.  I would like to figure out why before I drop this device off in his front room window.  ; )

Thanks for your help.

Answer : Problem: Trouble-shoot UPS not working

That can happen if batteries are stone dead.
Check the batteries first with a volt meter.
- Also look for any date codes...

If they are +12v you can try charging with a car charger but charge them as SLOW as possible as you don't know their condition. [Some car charges do +6v too.]
MONITOR THEM while charging. - If they get hot then stop.
