No more PS4 turning off randomly!

I was given an UPS without the battery (It had gone bad). So I bought this battery and I am using it to keep my PS3 and PS4 from shutting off during power surges and outages. My area goes through a few power blips here and there and it ended up corrupting my PS4 hdd and forced me to reinstall everything. This battery works great. I've already had two surges and the console stayed on the whole time. I recommend people get this for their PCs, consoles and networking equipment. It saves you so much time and money. Update: Since my original review, I have gone and purchased 2 more of these batteries for additional UPS. I hate throwing away electronics when they can be fixed for cheaper and prevent creating waste. These batteries allow me to breathe new life into these UPS.

Measure your battery!

Be Careful! There are TWO vastly different sizes for the battery for the APC Back-UPS ES Model BE350. Note that batteries are not returnable! I THINK the two batteries are the RBC (longer, 5.2 x 2.6 x 2.4 inches) and the RBC45 (more square, measures 3.54 x 2.76 x 4.21 inches). I use the latter. Make sure you MEASURE your battery and then order the one that specifies that it is the right size! That will give you the best chance of getting the right battery. (The only exception is if the description is wrong.) I have had good luck with the APC and Power Sonic brands of batteries. They seem to last a long time. I recommend once you find one that is right for your application, buy an extra one to have as later replacement!

Great bargain. Just be sure to measure first so you get the right model for your APC.

Great value. Local retail store was twice the price. Twice. Mine was not unmarked as in the photo but looks like similar product with UB1234k printed in white on the side. Fit was perfect. Make sure to measure your old battery and get one with the same dimensions. Also, keep in mind that the height measurement provided on Amazon includes the height of the connectors, not the body of the battery alone. So there could be a little variation there. Make sure you measure the height of your old battery both ways. The dimension given for height for this battery of 2.64 inches includes the height of the connectors! Don't be afraid to peal the APC label off your old battery to look for additional information. This was moderately helpful for me. See photos of my old battery with and without the label. The manufacturer name - Long, and the code WP3-12, which 3 amps 12 volts, are helpful shopping and ensuring you are getting the right model. Very pleased and if it lasts a few years it will prove to be a great buy. Mine arrived wrapped in bubble wrap inside a padded plastic envelope which had been folded over and taped tight around the battery. It was in excellent condition but I can certainly see how, given the weight of the item, damage could occur if it is dropped or handled roughly during transport. A cardboard box with padding inside would definitely be better protection, but I had no issues with condition on arrival and it was an easy matter to slice off the padding with my pocketknife. Similarly, I had no issues with the fit of the tabs on the battery with the connectors on my APC unit. The tabs on the new battery were a bit smaller but fit tightly inside the connectors first time with no finagling necessary. Orientation of the battery in the battery compartment is a little odd. Try to note - or photograph with your phone - how the old battery is in the compartment. To my mind, the battery goes in sideways on my model APC. But this is definitely something you can figure out in ten seconds through trial and error, which is what I did. See photo. Good luck. Highly recommended.

Good battery, good price.

My UPS would beep every time I turned it on, even without anything plugged into it. I ordered this battery and placed it in the UPS after I had finally figured out that the battery had to be put in with the terminals DOWN so that the lid would slide shut. (A diagram would be helpful for those of us who didn't remember which way the old battery was placed in there when we took it out several weeks before we decided to try a replacement. I finally found a diagram on the web.) I let the battery charge for several hours before plugging anything in to the UPS and then set it up so that my cable which has internet, TV and phone on it has everything backed up for forty-five minutes to an hour so that when we have short power outages (common here) I won't lose my phone service or my weather updates. Short story, it works as it should.

Fit and is working

Bought two yet both had the clip caps loose in box, but no sign of a short circuit or leak, so OK?? Installed easily in my APC BE-350G units. Arrived charged and worked immediately. It will take years to rate battery life, and I will update my review of there is a problem. I suspect it won't be as good as factory battery. One UPS now doesn't like it when I turn on my laser printer yet that seems it should be an issue with the UPS not the battery, but who knows, coincidence ??? I re-routed my computer set-up's power cords.

NOT for BE350R!

I bought this to replace one that my Dad has replaced in an APC BE350R UPS in 2012 (about 6 years). It was swelled when I took it out, and the unit was beeping. It was time. I used Amazon search and found this battery, was excited at the price, and didn't check reviews or measure my battery. It says it's compatible with BE350R, and average review score was solid, and what mroe did I need to check? So, while I guess that it technically is 'compatible' with my BE350R, in that the wires plug into the terminals on the battery, it does not fit into the housing. There is a gap on all 4 sides, and it's just a tiny bit deep to close the battery cover. Also, the battery is smaller, so presumably I've lost some operating time if/when the power does go out. Although I'm not positive on the math, because the old battery says it's 9 amp hour, and this claims to be 3.3 amp for 20 hours, so while I'm aware it's a new rating standard, I'm not totally sure of the conversion rate. I'll do some reading and see if there's any way to close that battery cover and report back. Hope this helps someone else like me who has a BE350R, but unlike me reads the comments for simple things like UPS batteries.

So far, so good.

So far so good. I just received this replacement battery for my APC Back UPS es350, and after swapping it for the old one, it seems to be working correctly with no problems. Previously, when I would plug the device into a wall outlet, it would sit and beep non-stop with the "replace battery" indicator light flashing. Now it is flashing green (and happy) again and the beeping sound is gone. I am always hesitant about using these "aftermarket replacement parts" especially when it come to batteries... (We've all seen the YouTube videos of people's batteries combusting and bursting into flames...) and I am hoping that won't be the case with this battery. I am giving it 5 stars now, and will update the review as time goes on. If everything keeps functioning normally though, I would say this was an excellent replacement part for the price.

So far, so good

Purchased to replace the original APC battery that came with the ES 350 Back Up unit, and no issues after two weeks. The reason I replaced the battery was because the ES 350 had begun to malfunction in the same way as another ES 350 I'd purchased around the same time had failed a month earlier. The ES 350 would intermittently lose all power (both hard-wired and battery) for a split-second at a time and on other occasions, after turning the ES 350 back on after having it shut down while on vacation, the unit would beep repeatedly even though connected to a live outlet. Throughout these two issues, the unit's "low battery" indicator light never came on, nor did the light which indicates any hard wire issues, but seeing as how now two APC units had failed in the same manner made me wonder if it was a battery issue. So far, replacing the original APC battery with this third-party one has cured the problem (and the cost was substantially less than buying a replacement battery from APC). If this "new battery cure" holds, I intend to purchase another of these batteries for the APC unit that failed (and that I unplugged from use) a couple months ago.

*********Disabled? Read my review before you replace your stairlift batteries***********

Impressive product and I will save you the research. I have a bruno sre 3000 stair lift in my home that I do not know a ton about since I didnt have it installed so I have zero paperwork on the product other than model and serial number. I started to hear it beep one night which is an indication that the batteries were going bad. After research on line the company website I came up empty handed and called a location company that installs this brand. For the LOW price of $199 PLUS mileage they would come out and do clean things and see what the issue is (not fix see). Then if it is the battery then I would have to pay ANOTHER $179 for the batteries (turns out they take 2) and installation. So I was looking at $379 for batteries. Long story short I called a battery store.. $38.79 EACH making two batteries almost $80. I found the same battery for $16.99 each here on amazon.... $30 total for batteries. Got them 3 days ago and installation was a total breeze, once you remove the cover the batteries are right there and took about 2 minutes to swap out. So save yoursel some money and buy these instead of calling a repair man or spending at a battery store.

Battery Works As Expected. Replaced the APC OEM that came with the unit. No problems.

Read many reviews that said the battery won't fit. Well, it fit into mine purchased in 2000 for the APC model listed in the item description. Just make sure when you're looking at the bottom of the APC unit where the battery lid is, you have to insert the battery with the wire side in first towards towards the inside of the unit. Otherwise, the battery lid will not close blocked by the connection. The picture attached shows the INCORRECT placement of the replacement battery.
