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.

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,
