I have a 650VA UPS. It has a 12V 7.2A Battery. The amount of backup time that it provides is low so I'm thinking connecting another battery of the same model to it. I'm connecting the Batteries:
Batt 1 => (+) (-)
| |
Batt 2 => (+) (-)
It will extend my Backup time right? Also the Battery need a voltage of bitween 13.4 - 13.7V to recharge. It will work right?
If I connect it, it would mean that the UPS will become a 14.4A UPS right?
Thanks

You want to keep the same output voltage...connecting the + to + and the - to - will give more runtime current. (batteries in parallel)
If you connect + - + - (series) it will increase the output voltage and could damage the circuitry

Some higher end UPS units have the option of daisy-chaining extra batteries.
If the one you have does not support that feature (as per the manufacturer) I STRONGLY urge you to refrain from doing that.
This device protects your entire PC .... & modifying it will void all warranties & insurance.
Spend the extra dollars ($100 or so) & get a 950va + unit which will give you the power you need as well as peace of mind.
