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.

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---- 8/11/2014Just 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------2/11/2015Batteries 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------3/5/2016Both 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--------4/25/2017Both 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---------3/2/2018Both 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 -----------6/1/2020Sorry, 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.

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

fits and work perfectly,

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.

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.

This Power-Sonic PS-1290 (9.0 Ah) is a great fit and function for my good old CyberPower 850PFCLCD backup power supply. It arrived charged to 12.81 Volts (no load). After installation and making sure it's fully charged, my UPS is happy, indicates full battery charge, and estimates 19-minutes of runtime. After 1 day of use, it seems to be good.Nice that I could get this 9 Ah version instead of the regular 7 Ah (longer run-time, for just a few bucks more). Pro tip: This new battery came with a bare (+) terminal, so I moved the terminal protector from my old battery to this new battery.For comparison, my previous battery was the original one that came in my UPS ("B.B. Battery HR1234W") and it lasted me 9 years, active 24/7/365, through hundreds of power blips, sags, and outages, powering a Mac Mini, TV, soundbar, and a few other low-power devices. No problems, so I hope this Power-Sonic PS-1290 provides similar success.Misc: This battery has a "Made in Vietnam" sticker on the bottom vs the old B.B. Battery was Made in China.
