Hi,
I know very little about electronic hardware other than PC components. I have an Uninterruptable Power Supply whose original batteries ran out of juice after several years. This UPS, the Patriot Pro II 750, uses two 12V, 8Ah sealed lead acid batteries. The UPS has two leads -- one positive, one negative. Each goes to an individual battery. The original pair of batteries were jumpered together in series to complete the circuit. Problem: I lost the original jumper cable. I've purchased two new replacement batteries. I need a cable to jumper them together. I've searched the web and this has proven harder than I thought. Maybe I'm not using the right terms. Or maybe this is so trivial that people fabricate their own. The SLA batteries have F1 terminals. I'm assuming I simply need a short cable with F1 connectors at each end. I'm not really comfortable fabricating my own for this kind of application (involving batteries). Someone with more knowledge than I tells me that the jumper for this UPS did not have a fuse, it was just a simple cable. Any advice? Is there somewhere I can simply buy a short jumper cable with F1 connectors? Is there someone who can put one together for a few bucks? It's frustrating that this UPS is sitting here with brand new batteries and I'm stuck because of my own error in discarding the original jumper cable. thanks, Aaron |

Any auto electrical shop can do this for you in one minute or you can buy the parts and crimp tool at an auto supply shop.

Hi!
Problem: I lost the original jumper cable. What does the manufacturer of the UPS have to say? They might send you one, if they are still in business. Or maybe this is so trivial that people fabricate their own. The fabrication part will be easy and requires easily obtained tools, wire and connectors. If you don't want to make one, or feel uncomfortable doing so, a number of people might be able to help you--electricians, car audio installation companies, well stocked and knowledgeable electrical supply houses...even a dead UPS might yield a usable cable if you can find one of those. The SLA batteries have F1 terminals. I'm assuming I simply need a short cable with F1 connectors at each end. I'm not really comfortable fabricating my own for this kind of application (involving batteries). Use a wire that is similar in size to the the others that feed the batteries. The same goes for the connectors. There's no fuse in this wire or anything special like that. (If you were to look, you'd find the fuse(s) on the main board in the UPS.) The only thing you'd have to be careful of while you're working is an accidental short of the battery terminals. That's very unlikely to happen. William |
