Wiring for the double lead acid batteries in a UPS system
Wiring for the double lead acid batteries in a UPS system
Hello, I recently purchased two lead acid batteries for my UPS system. It’s an older model of the cyberpower 1350AVR that has already been discontinued, though a newer version with the same number is available. I now realize I don’t have the plastic connector nor the wiring linking the two batteries inside. I’m considering making a makeshift replacement for the plastic part, but I still need the wiring. Could anyone inform me where to find these wires and what they’re called? Additionally, how many wires do I require and how should I connect them to the batteries? It would be more cost-effective to buy OME batteries instead of this option. Any advice would be greatly appreciated!
I don't understand the exact response, but it's clear that if those lead-acid batteries aren't genuinely sealed, they will corrode and harm the interior of your UPS. During charging and discharging, acidic fumes are typically emitted for lead-acid batteries. You wouldn't want these in your home near a wall or without proper ventilation.
Generally you should look for a wiring harness.

You shouldn’t use third-party batteries for the UPS.
It’s unclear how they were made or assembled—possibly refurbished.
Any wiring harness claiming compatibility is likely unreliable.
Harnesses may be low quality, thin, poorly insulated, or have loose connections, posing safety risks.
If conductors heat up, they could fail completely.
Best to avoid the risk: keep original batteries and buy a new UPS from a trusted source.
Choose the latest model with full warranty for better reliability.
