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.

UPSes pass eval if they:

• have a battery hatch
• are rated at 400 VA (voltamps) or greater
• are not made by a company that is out of business. immediately recycle the following:
  • Best
  • MGE
  • CyberPower

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 are recycled. To recycle:

• 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.

Batteries are evaluated physically first:

• are there any cracks?
• bulges?
• other physical damage?

If so, place the battery in a 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.
