Power-Sonic PS-1290 12 Volt 9 Amp Hour Rechargeable SLA Battery (F2 Terminals)

Okay I have a lot of UPS's. I tried the "PowerStar" brand, which didn't fit (a little too big), overheated, leaked acid, and failed quickly. Now I'm back to PowerSonic brand. Hopefully these are legit and will last a good while. They were delivered quick, packaged well, and fully charged. And they fit in my UPS's perfectly.

I've used these batteries in my APC ups systems for many years. For me they've lasted a minimum of 5 years and a maximum of 7. They are my go-to batteries for personal ups systems.

Perfect drop-in replacement battery for the RB1280A in my cyberpower 825 AVR. Exact same dimensions, capacity numbers, terminals, perfect. Manufacture date 3 months old (Ordered December 2025, received mfg date stamped September 2025). Pretty pleased.

Replaced the battery in my Pickleball machine. Fit perfect

I've had good luck with these, but one of them I got "ships and sold by Amazon" was used and defective. The ships and sold by Amazon units don't come with any packaging, just the bare cell, but other than the defective unit the others were fine and about 5 months old. The ones sold by "Ace Comp Solutions" and shipped by Amazon come with the cells packed in a thin box with plastic covers on the terminals and were about 7 months old and in great condition. I'll keep buying these, as they are good cells at a good price, but make sure you didn't get a used one.

Absolutely horrible battery. 1st one ordered was showing a mfg date of 2019, 5 years old). Complained and they sent a new one. You can probably guess, yep, 2019 again. To boot, 1st power outage the device drained and came back reading about 10% capacity left in the battery from what a new one should have. Shows 100% charged but the runtime is next to nothing and it shows 'OL LB' (online low battery) constantly. DO NOT BUY THIS PRODUCT; unless your looking for a paper weight. If I could give a negative review I would. Look at my reviews, I don't normally give bad ones like this.

Great batteries for a fraction of the cost for what costs to go out and buying a new UPS. Had to get 2 for a 1285 geeksquad UPS. Was Quick and easy to swap out the old ones and pop these in. Recommend taking pics and writing in permanent marker on the contacts of the wires when working on the UPS when changing out to eliminate confusion, when putting them back together. Update---- 8/11/2014 Just had My OTHER 1295 geeksquad UPS die in the house. I used this one on my entertainment center. Had the previous one on my computers and is still chugging along normally with these batteries in there. Bought 2 more to replace the batteries in the one that just recently bit the dust. They seem to be working well and the monitor on the program is liking them as well. Had 2 brownouts and a blackout in the time had them and was still working. Update------2/11/2015 Batteries are still going strong and had 2 blackouts and a couple brownouts in the time frame of owning them. Have witnessed multiple power issues in my apartment when these were in the UPS, and they are still coming back and testing ok in the software and the hardware tests. Great batteries, and have no doubts about getting more. Update------3/5/2016 Both UPS are still working without any issues and still maintaining charges. Even through multiple brown/blackouts and lighting storms. Love these batteries and will be buying and recommending these batteries to anyone who needs replacements to anyone. Update--------4/25/2017 Both UPS backups are still going strong, and have had multiple blackouts and brown outs the past couple years. And these things ran my internet and TV etc for a good 2-3 hours before giving out (2 per UPS). Was using LED TV and fire TV on one, and just modem and router on another. Update---------3/2/2018 Both sets of batteries are going strong on both UPS'es. They have been up for almost 4 years and have been through multiple brown outs, black outs, and TONS of dirty power running through this complex. They kick on from time to time from a flux of dirty power coming through the port. Update -----------6/1/2020 Sorry, bit of a delay on the update. All things considered in all of this chaos. Had two UPS battery backups go Kaput. One completely bit the big one. My complex is full of dirty power. Just glad it took out a 100 dollar UPS and batteries rather than nuking 1000's of dollars of electronics. Saved my 4k TV, 4k receiver, Multiple consoles, Blu-ray player, Media computer and various other audio devices hooked up to it. These batteries replaced the other one that simply needed new batteries. Bought another set. Voila!! up again and electronics are happy.

Great fit for my UPS, higher capacity than original.

Excelente producto y buen precio 100% recomendado me llego con 1 semana de anticipacion a la fecha de entrega ya esta montado en mi UPS y trabajando excelente llega con el 80% de carga las pilas por lo que hay que ponerlo a cargar mínimo 12 horas antes de conectar aparatpos en el ups

Great battery used in a aqua vu camera last a whole fishing trip (6-7 hours) on the whole time

Great battery, holds it charge for a long time.

Encontré está opción más económica, ya que las "originales" de cyberpower están al doble de precio, ya veremos que tal funcionan, cuando me llegaron ya estaban practicamente cargadas, y en las pruebas parecen funcionar muy bien. Ya veremos cuanto dura. Ocupe dos baterias para el Cyberpower 1350 VA.

Buena calidad y llegó rápido.
