12v 12Ah F2 Terminal Sealed Lead Acid Battery (1 Pack)

The batteries in one of my UPSes were shot and needed replaced. It is much more cost effective to buy these over the ones from APC. Just need to reuse the fuse and power connector from the old set of batteries. These ones are actually a higher capacity battery than the original and provide a longer runtime. They've worked well now for several years and are probably approaching time for replacement. Definitely gotten more than my money's worth out of them.

Bought 4-months ago (Mar-2020) and still working great in my APC BackUPS Pro 1100.These batteries keep nice & cool vs the previous battery pack which heated up and deformed inside the case.And great price compared to OEM $140 price tag.I live in an area with constant brown/blackouts.The batteries hold strong through all power disruptionsOf course, it depends on what is attached, but my BackUPS running these batteries provide53 minutes of power during a total blackout.

This is a set of two batteries for the APC Smart UPS 1000. It replaces the single battery pack originally installed (which is actually the exact same two batteries that are provided here shrink wrapped into a single "pack" by APC). The installation did require removing the link wire with 60A fuse from the original battery pack (connecting the two batteries to each other's +/- terminals) and transferring it to the new individual batteries. The fit of the batteries is perfect and they function fine.The description really should mention that it is two batteries designed to take the place of one (even though the original "one" is really two batteries shrink wrapped together anyway), and it should mention the need to swap the jumper wire as well.5 Stars for the product and 4 Stars for the description.If you are handy enough to feel you can swap your own battery the 1 battery "pack" vs. 2 individual batteries as well as transferring the link wire should not bother you at all. That part is easier than figuring out how to get the UPS open.

I have ordered 15 sets of these over the past 9+ years. The last set March 2023 did not last 1.5 yearsThese batteries should last at least 2 years. Bad batch perhaps. ?

1/3 the cost for my ‘end of support’ UPS batteries. Work the same as the ’name’ brand.

I have an old SmartUPS 1000 battery backup. I ordered the batteries from Amazon in July 2023. Now less than months later I started receiving that sulfurous odor of battery issue. When I went to touch my unit it was extremely warm and not exhibiting any battery failure warning. I shut down my devices and then the UPS. After the unit cooled down, about 3 hours, I opened the access panel to the batteries. The attached photo shows the extent to which the "non-failed" batteries have expanded in the enclosure. The previous set of batteries lasted nine years, which is exceptional in the opposite sense.

I purchased this battery because it was significantly cheaper than the APC branded battery replacements available elsewhere. I'll echo what another reviewer said: This item is two separate batteries that need to be joined in series to function properly. You'll need 10 gauge wiring to make the connection from one battery's positive terminal to the other battery's negative terminal, with spade connectors. Fortunately, the last off-brand replacement I bought actually had a small cable with a fuse already, so I re-purposed that. Once connected, both batteries slide snugly into the APC unit. I did not have any problems with fit.

I was concerned about buying these batteries because some were very expensive from other sellers and these cost considerably less. I put two of these into an old APC UPC and they work well. I'm glad I made the purchase.Udated: Still no regrets. These batteries are performing well and saved me from having to purchase a new UPS. Installed in 2017 and still going strong. February 2022.

It is a battery, and it seems to be doing its job. It seems that pricing as listed included all taxes and shipping.Purchased March 16, 2014. Unit is now looking for a new battery set as at Sept 2015.
