I have an APC Smart-UPS 1400 SLA battery pack, part number RBC7. It's brand new in box, but about 4 years old.
I'm hoping to use this battery as backup DC power for power outages and have some questions:
1. Since this is an unused battery, do you figure it's dead or is it problably still good? Any way to check?
2. How can I charge this battery, assuming that I don't have a 1400 series UPS to charge it with?
3. Any idea what voltage and amperage this guy is? the box says it's 2 12V batteries, 17AH. Not sure if that's then 24V at 17AH or 12V at 34AH. The interconnects between the two batteries are sealed up, so I can't see if it's serial or parallel.
