UPS (power supply) Eval1 Howto
Batteries and UPSes are evaluated separately. When removing batteries, be careful to find the clips for the wires: do not cut the wires.
- have a battery hatch?
- are rated at 400 VA (voltamps) or greater?
- have a manufacturer who still exists? immediately recycle the following:
UPSes that pass Eval 1
Get a keeper tag on them with any information you can fill in, and are put in the Eval2 pile.
UPSes that fail Eval 1
- Tally on the sheet
- Mine aluminum heatsinks.
- Fully recycle if the pile is large, leave under the small bench against the wall if it's small.
Evaluate physically first:
- are there any cracks?
- other physical damage?
If so, using gloves, place the battery in a sturdy plastic bag and recycle.
With a voltmeter, test the terminals. If you get a negative voltage, you've reversed the terminals. Batteries are rated at 6V, 12V, and 24V, and must display at least their rated voltage. So a 12V battery showing 11.8 is a recycler, but showing 13.7 is fine.
