SigmasTek SP12-9 - 12V 9AH F2 SLA Battery - Replaces: Universal Power UB1290 (40748), UB1280HR (D5785), B&B Battery BP8-12, HR9-12, Vision CP1290, Yuasa NP9-12

Very good batteries. I've been using them for a little over a year. They work great. Well worth the money.

This battery was exact fit for my tire air and jumper box it works great again, detentions we’re precise.

I ordered 2 of these batteries to replace old batteries that had failed. They were bigger than the original batteries so I had to make my own cable to connect the 2 batteries in series. I was lucky in that Cyberpower uses the same case for its larger power output model. I just had to rotate the larger batteries to fit into the case. I now have slightly larger capacity (9ah) instead of (7.5ah) batteries. This should slightly increase my battery run time as well.

I received 2 1500W APC uninterruptible power supplies with dead batteries for free. I replaced the dead batteries and they work like new again. I couldn't find a lower price for these types of batteries. These are a very good value especially if you have Prime. I have had probably 10 or so power flashes/brown outs since setting these up on both of the gaming PCs in my house - including monitors and router/internet, and have had no issues with them turning off. They work exactly as expected. Would recommend.Just as a note, I received the wrong battery type the first time I ordered a pair, but that was resolved very quickly and I received the correct ones only a couple of days later. They did not ask me to return the wrong batteries. The second pair that my sister ordered arrived correctly the first time.

The four I bought worked great in my APC SMX1500RM2U. It fired right up and read the batteries at 100%. I'll revise if I have any problems long term.

Our household electronics UPS devices get a workout from frequent power outages. That means their batteries get discharged and recharged often. That has direct effect on battery life. These have help up well..

Second time i purchased this brand of battery. The first one lasted approximately 3+ years in my Cyberpower 825AVR UPS. These are meant for safe computer shutdown in case of power outage, not to keep it running for any length of time. If you want that, you will need to sped a lot more $$. Cheers!

Battery fit perfectly in my old TripLite G1010USB UPS system. The battery came with the correct F2 connectors.Note: I had previously purchased the same brand of batteries several years ago for my other UPS, a CyberPower. The batteries also fit that unit, which is why I am a repeat customer.Having said all that, I don't know how durable or effective these batteries are given I have not run into any power out episodes that triggers the UPS' battery output.
