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

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.

hooked them up together for the 36 v needed for my scooter bike, works great so far.

I just purchased my 5th battery and continue to be pleased with the PowerSonic battery in particular. This brand assures a quality battery. Some batteries claim to be "equilavent" and while they may be close, for important uses, this is the one to buy. I use this battery in many devices, in my airplane running critical avionics where I need the best since my life is on the line. I use this battery to backup my home alarm system and another in my UPS power backup for my PC. It's very fortunate that the same battery fits in all devices. Over the last few years this same size and shape has evolved from 7Ah, to 8Ah, to 8.5Ah and now 9Ah. Some of the copy brands are behind in their technology and can only get 8Ah in the same size package. That's a clear sign that their batteries are not up to par. Also, notice the weight, you can't get more power in the same package without increasing the weight using current technology. If you don't need the full 9Ah capacity and life, then perhaps the lower priced generic brands will work for you? I am able to get 3-4 years out of a battery. These batteries like to be kept charged; if you allow yours to drain it'll hurt the life. If you drain and cycle them expect 300-500 cycles. Also, there are special Gel battery chargers, such as the Battery Tender Junior. Battery Tender 021-0123 Battery Tender Junior 12V Battery Charger This charger is designed specifically for these batteries and will keep them working properly. 5 stars for a solid well working battery that performs as needed.

I have used PS for many decades. I have never had an issue with output or longevity

Have a CyberPower 825AVR CP825AVRLCD-G UPS. It seemed like it was working fine, but after I unplugged it to move it and turned it back on, a relay would click, the display would read 0 and the alarm speaker would turn on. Figured it was probably the battery. Tried some other batteries I had but they all did the same thing. Decided to take a chance and replace the battery since all of these batteries are a little old. Did some research and found this one, went on their website and it looked like it was a quality battery. Bought it from Ace Comp Solutions. It arrived in a small box a little bigger than the battery, opened it and it was just wrapped in brown paper. The one spot where there was an opening in the paper found that the battery had a flattened dent on the top corner. Otherwise the battery case looked find. Label on it said "Made in Vietnam". Installed it and was going to let it charge for a while but decided I couldn't wait, tried powering it up and it powered up a-OK without any issues. So it's so far so good, we'll see how long it lasts for.

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.

Ordered two of these batteries, one arrived completely fine. The other arrived measuring 1.1 volts nd would not take a charge. Amazon's FAQ says a 12 volt battery should arrive with a voltage of 12 volts or it might be bad. When I try to return it choosing the "defective" option, the Amazon web agent puts me through an endless loop of troubleshooting FAQs that never gets me to a resolution to return the battery. I suspect this one has made the rounds with other people choosing "didn't need" or "arrived late" as the reason to return it when they ran into the same problem, sending it back into stock for some other poor sucker (like me) to get stuck with. (It had no packaging, unlike the other one I ordered, which came wrapped in bubble wrap and tagged with the typical Amazon inventory sticker.) So beware! If you take a chance buying an AGM VRLA battery on Amazon, you might get stuck with a bad one with no honest way to return it!

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.

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.

La batería funcionó sin problema en el APC Back UPS Pro 700 y reporta buena duración de la batería. El único detalle es que le falta la lengüeta para sacarla, cuando tenga que cambiarla va a haber que voltear y sacudir el NoBreak, pero es sólo un detalle.

Buena calidad y llegó rápido.
