Weize 12V 9AH Rechargeable SLA Battery For APC UPS Computer Backup Power (BX1300LCD), APC Back-UPS NS 1250, 2 PACK

These last about two years

Replacement battery for kids atv . Good value,seems just as original battery.

I have had these batteries for 2 years now in a kids rideable jeep, and still working just fine. Holds a great load. Lasts a long time. Kids ride the jeep alot so they get there use.

For a UPS, these batteries are expected to last 3-5 years. These lasted 3 years and then dropped to ~11% capacity. I put 12 of them into 3 parallel chains of 4 as that is what my UPS and associated battery expansion box took. So to get down to ~11% of rated capacity, all 3 chains must have gone bad. I still give it 4 stars. The reason being since installing the batteries, I have experienced a number of long duration power outages causing the batteries to drain down to 0% and the UPS to reach low voltage cut-off. Some of the outages I was around to hook up a generator, but that still took some time to setup, warm up the generator, and then have it take the load. And the bad thing about all of this is I live in the middle of a large city that doesn't experience too much extreme weather, granted it has been getting worse as of late. So I give these batteries a pass this time due to a combination of a crappy utility and global climate change causing things to go from basically no extreme weather to periodic extreme weather, leading to these batteries taking a lot more use and abuse than what I used to experience when I regularly saw my UPS batteries last longer. I am still trying a different brand to see if it works out any better, but as extreme weather isn't getting any better and the utility is getting hit with more and more lawsuits, I doubt better lead acid batteries will actually last any longer out here. After the next set though, it will be getting to UPS replacement time anyways, so probably swap out the UPS with an all-in-one solar inverter and an LFP battery, especially as LFP batteries can take a lot of use and abuse and that is exactly what is needed as the planet edges towards being uninhabitable.

Although not designed for an APC UPS, that's where I use them, in series to produce 24V. The APC BR1500G has a port to add a supplemental battery pack, but at over $200 it can be a little expensive. So I bought this two battery pack, used 10 gauge to make three cables with F2 terminals to connect the batteries in series and then connected them to the back of the APC BR1500G, where the battery pack is supposed to be hooked up. It works like a charm and much less expensive than purchasing the APC External Battery Pack, BR24BPG. The APC BR1500G maintain the battery pack charge, so there's no need for an external charger.
