APC Back-UPS ES 500

[Robotnik]

It says the output current on the Backup part is:

120V~, 60Hz, 2.9A
120V~, 60Hz, 4.2A

Totalling 7.1 Amps.

Would it be possible to have to batteries in Parallel and increase the
current output and/or the running time?

And if it would.... would this cause problems for the charging circuit?

Thanks,

Nic

Putting on more batteries in parallel will allow for longer running time
during a power outage. When putting on a battery assembly with a higher
current output, the charging current will also be increased. The charger in
the UPS will have to be rated to support the increase. The proper solution
is to get a larger UPS.

The only way to increase the output current rating of the AC output, is to
have a larger inverter output stage. This would be a major re-design of the
UPS.
