So, I have two identical UPS units. Both are TrippLite Backup Office 350VA. They both quit providing backup power ... around the same time (about 6 months ago). All outlets worked but the battery never kicked in (the red low battery indicator flashes).
Having verified the battery type - CP1245 ... I purchased two replacement batteries. But that did not help. The red battery indicator is still flashing.
I put a voltmeter across the battery terminals. It reads around 10.5 Volts for both batteries.
I check the voltage across the pins that connect to the battery terminals (without the battery) ... and it read around 3 Volts. How come !
Can someone tell what the charging voltage would be. The 3V sounds kinda low. Its a 12 V battery.
Thanks !!
