Martin,
I have aquired a Belkin unit with very identical symptoms.
Urgh this APC is to replace an old belkin 800VA unit that was badly designed.
You had to bend open a metal cage to insert a replacement battery.
Did it once and swore when the second battery went i would just get a new UPS.
In my case one
battery terminal had actually corroded and fallen off, so it was a pretty
simple fault to find. Typically, the Lead acid batteries used will
be 6Volt or
12Volt, sometimes wired in series to give 24Volts. Disconnect the
battery(ies)
and measure the voltage across them. If you are move than about two
volts from
the typical values above, it's likely that the battery is dead and needs
replacement.
Its 4.8V but they are not getting warm like i would expect a dead
battery to do.
IIRC.
There are places which sell replacement batteries on the web at reasonable
prices.
Not really convinced yet that it is the battery.
