I easily changed the battery in the APC Back UPS 950 after 7 years, the case fit perfectly. Now, whether it will last as many years, I don't know, time will tell, but even if it lasts 2-3 years, with the cost of this battery, it's worth replacing it again.

It just works but it doesn't last long on a UPS and it can leave you stranded without you realizing it. However, it might also be the UPS's fault. For me, on a BELKIN, it lasted 9 months and then it couldn't take it anymore.

It was used for UPS battery replacement, and it has been working flawlessly for over 6 months. The replacement process varies from UPS model to model, as does the compatibility of the battery size.

Purchased for use in UPS.
Charged, exactly as it should be.
How long will it last? We will see and update.

Maybe you get what you pay for? In a UPS it lasted only 1 year even though it was very fresh when I got it. I have to replace it now and I will go for a CSB. I hope there is no issue with liquids since I haven't opened it yet.

I use it in my little one's electric car... We have tested it for 1.5 hours continuously without any problem in its operation.

Installed in APC 900 Pro UPS without any problem in November 2025, and if they last 2 years I will be extremely satisfied since I was using original APC ~120 euros which lasted almost 4 years (at best).
I am not giving 5 stars because it has not yet been used during a power outage to see its behavior.
I will return to update the review depending on the lifespan.

Because I see many comments about UPS batteries not lasting, for APC UPS you should get CSB batteries, they are the same as the original ones

I got 2 to replace the old ones in my speaker. They broke within a month. They are very sensitive and if they are left unused for a while then the level drops and they break

2 times in APC UPS 1500 did not last more than 1.5 years.
Both times I bought them in pairs, one of the two failed after 1.5 years.

1 month: Works normally. In an APC UPS, which had a 12V 9A battery, it fits in size.

the battery was fully charged following the instructions to the letter, after about three weeks during a power outage the ups was fully discharged and when I tried to charge it the battery would not charge, either with load or without, so wasted money

It has been installed in a small UPS for PC and router. It lasts 2.5 - 3 years.
This is the third time I have replaced it.

Good company that is also used by technicians. I have had it for 10 months. Normally, it should last at least 3 years. If an issue arises, I will update.

It will not be the first time I buy this particular battery. The purchase is made to meet the needs of a home alarm system. The duration it lasts in this system is about 3 years. Generally a reliable and relatively long-lasting battery.

I use a pair for APC 1500A UPS. The previous same ones lasted exactly 2.5 years with several power outages. I consider them good value for money. I will choose them again.

I got it to replace a NOD battery with the same characteristics, for the UPS I have on my desktop PC. So far, I am completely satisfied. I hope it lasts me 3-4 years

Cheap, good for one year. In the second year it wouldn't hold a charge and after a while it wouldn't even turn on the computer. The negative terminal was filled with salts and had leaked fluids.

It had leaked fluids (possibly during transport). Check their condition upon delivery because they did not accept my return.

Replaced the battery in the Powerwalker VI 1000 STL UPS. It works perfectly. I didn't time the duration. The UPS has 2 routers, a Google Home Mini, Hubitat Elevation, and a QNAP connected to it. The plugs and dimensions were the same, replacement took 10 minutes.

Immediate shipping from the store of purchase. It seems to be a very good battery and I currently have no issues with voltage fluctuations. It responds very well. As for its duration, it will be seen over time.

A great battery with an excellent price/performance ratio. It is important to know, of course, that UPS systems are not televisions or radiators to operate continuously for 20 years without maintenance. The batteries of UPS systems are considered consumables; we usually replace them every 2-4 years, and at the first suspicion of reduced duration or any other problem, we definitely open and check if they have swollen or have leaks, etc. If the price remains competitive, I will definitely prefer them again.

The first one I had lasted 2 years and the second lasted 1 year and 3 months in a small computer ups.

Very good and Greek battery. This I can say, as a specialist in the field with 20 years of experience. Quality/price ratio

a great battery for its price, you don't need to pay for more expensive ones, it does its job exceptionally well

Edit 2/7/25:
Almost a year later, the battery gave out. The power went out today, the UPS made a few quick beeps and then shut down. This one cost 18 euros and lasted 1 year, the official one which is 60+ barely lasted 2 years, so this one is probably more worth it.

It works but the UPS (APC Back-UPS 950VA) is not happy. The self-tests sometimes fail and say the battery needs to be replaced, but when the power goes out, it does its job as it should.
With a normal battery, this would be a big foul, but when this one is 18€ while the official is at least 60€, I can't really complain much.
I've been using it for 5 months now and it doesn't seem to have any issues.

In 15 months off, the ups doesn't last even a second. Measured in V and an attempt was made to charge with an external charger ... nothing. I had bought again and again in two years they broke. I will try others.

I have bought around 10 batteries over time. About two years is their lifespan, but at this price, what can you expect? The last one (see photo) however did not last 6 months and ended up like you see it...

It kept me alarmed for 2 years and 4 months, it's not perfect but okay tolerable. I got the same one for replacement.
