Re: APC UPS units - troubleshooting

I'm thinking the same - the battery doesn't even light up my charger - 12 hours and still at 4V - open short, I suspect.

Not a total loss, though - I found this really cool site

Thanks guys.

Re: APC UPS units - troubleshooting

My APC BE500R UPS is much smaller than some of those shown here... It has a single 7.2A 12 V SLA battery.

It's been sitting unused since we moved house in June last year.

I went to plug it in today and it shows no signs of life - the power LED doesn't come on.

There's definitely power at the end of the lead, the thermal shut-off is closed and power gets to the main board.

It was working when we packed it up, back in it's original box.

The battery is toast - reading 4v....
