Compatible with APC Back-UPS CS 350 12V 9Ah UPS Replacement Battery Beiter DC Power

Battery is exactly as illustrated. Used in our burglar alarm, not in a UPC. Working perfectly.

This is my second purchase of a replacement battery from this vendor for my APC CS350 backup power supply. These batteries are a perfect fit and will last approximately 5 years before they need to be replaced. Word of warning, use caution when replacing the battery. My old battery must have developed a small leak in the seal and some of the battery acid leaked out onto the carpet ... the carpet was destroyed in a matter of seconds.

Fit great. Seems to work fine

Needed a battery for my little APC battery backup to power my CCTV Cameras. This battery fit perfect.

Was tired of hearing the "replace battery" alarm on my UPS. Also was not happy when power went out for just a moment and everything shut down. New battery and back to staying alive long enough to save everything and shutdown computer properly. Also no more alarms going off!

This replaced a 5 year old version of the same battery. It was a pre-emptive change as the "replace battery" indicator had not come on. The terminals are the correct size and fit tight (APC CS350 & ES550).

Good quality and good price

Worked like a charm. Popped the old battery out, put whatever was on it on this, popped this one in, and was able to get my UPS back up and running (and working) without having to buy a new one. I've used this brand for a few of my other ones as well, and it seems to work really well.
