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.

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.

Works as it’s new. It’s a battery. Charged to 100%. Good value compared to OEM. Longevity unknown though.

I bought this replacement battery based upon the favorable and helpful review by FIX IT GUY on October 16, 2011. My Tripp-Lite Omni from Costco would not stay on (and eventually refused to turn on) after many years of use. I followed FIX IT GUY's instructions/notes, and they worked really well. I had a long screwdriver, but it was a narrow flathead type (however, it was still able to turn the screws without stripping the heads). The screws are relatively short. I had no trouble carefully lifting the back cover off part way to get just enough room to replace the battery. The battery cables fit tightly, but they will readily wiggle on and off the terminals. As FIX IT GUY says, the trick is to get the circuit board back into the plastic grooves of the rear cover. However, because FIX IT GUY warned me in advance about finding the grooves for the circuit board, I was able to get the cover back on quickly (in under 30 seconds or so) -- no frustration whatsoever. If I had an actual extra-long Phillips screwdriver, I think I could have replaced the battery in just a few minutes. For the price of this replacement battery, it sure beats buying a new unit. Just be wary of touching metal parts (as with any UPS battery replacement) -- however, it seemed like my fingers had plenty of room to work with inside the Omni 1000. P.S. The original battery that came out of the Omni 1000 was a "Vision CP1290 12-volt 9-AH" sealed lead battery that was made in China -- these original UPS batteries are nothing special to begin with. So it's totally worth the time and money to replace UPS batteries when necessary.

Replaced the battery in my Pickleball machine. Fit perfect

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

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.
