[rescue] [Slightly OT] Smart-UPS 1400 Battery replacement

[James Fogg]

On Fri, 03 Aug 2001, THOU SPAKE:

Assuming they are near discharge now....

1) disconnect all the wires from the batts.
2) measure the voltage on each batt, they should all be within 1/4 volt of the
average of all their voltages (if not, deadsville).
3) if any batt is below .5 volt per cell, then the batts are gone. each cell is
good for 1.5v, so if its a 6v batt, then thats 5 cells.
4) re-connect and charge for two days.
5) place a dead load (resistive load, like a bunch of light bulbs) on the ups.
Pull the ups plug and see if the ups has decent output (measure it and watch
the bulbs). This is a cheatin way of measuring load capacity.
6) disconnect batts and measure for equality like in step 2.
