Very good for use as an alternative solution to the original APC for UPS 1200VA (2x12V). The difference with the original APC is that the lifespan of the CBS is up to 2 years, while the APC's is 3-5 years. The price of the original is more than triple.

The UPS never worked again like the original ones. With every voltage drop, the fault light flashes and it needs a reset. It never recovers on its own.

It arrived immediately, fit perfectly on the UPS (powerwalker vi 850), I turned on the PC, turned off the main switch and it lasted for more than a minute, I got bored and turned the power back on. Very satisfied! The previous original one, after two years, couldn't last even a second without power. I hope this one lasts for 3 years as I read.

They really do last longer (in terms of time) than other brands, I use them for heavy use in sun/heat to inflate an inflatable with an external pump that consumes quite a lot of power.

It was measured at over 12 volts when received, installed in a Powerwalker VI 850 SHL with absolutely no problem, this particular brand is by far the first choice for replacing the original. Although many manufacturers, e.g. APC, BLUEWALKER-POWERWALKER, have these pre-installed.

It is better than the RBC17 from APC. The only difference it has from the one that was inside the UPS BX-950U is the APC sticker, which costs an extra €45!! I won't comment further because I might be censored.

I got two of these as replacements for two 7Ah batteries that my APC Back-UPS 1400 UPS had. Exactly the same dimensions as the original ones that came with the UPS from the factory, and as far as I could tell, the same brand as well, since under the APC sticker they were exactly the same. So, I saved quite a bit of money and upgraded from 7Ah batteries to 9Ah.

Two were purchased to replace the factory battery set in an APC BACK-UPS 1400 (1400VA/700W). For a month now they have been working perfectly and have already been tested during a power outage.

The top battery for UPS so you can forget about changing it for 3-4 years in Athens. Used in a Legrand KEOR1200 UPS and replaced after 4 years in an office in Kallithea where the PCs never turn off, but power outages and voltage drops are frequent (1-3 per week in summer, 1-2 in winter).

The battery was originally installed in an Eaton 850VA UPS that was purchased in 2020. Up until today, 8/2025, 5 years later, it keeps the PC on during a power outage when you're not doing anything heavy, but it doesn't keep it on during gaming. I have a Sapphire Nitro 7800XT card and a 5800X3D CPU. Of course, I will use it again

Absolute compatibility with APC RBC17 batteries, more economical. Personally, it revived a BX950U-GR UPS

It was placed in an electric sprayer. Time will tell how long it will last. Made in Vietnam.

At home, I have 3 UPS that take batteries of this type, but at my workplace, I deal with many UPS from various manufacturers that use such batteries. An UPS will need new batteries approximately every 2 to 4 years, depending on usage and the quality of the battery it had. Personally, I don't buy anything else except for these CSB and the corresponding YUASA depending on which of the two I can find at a better price and available. Regarding the specific CSB model, I should also mention that the model HR1234W, which also states F2 immediately after, has wide terminals that are the most suitable for connection with UPS.

Purchased for battery replacement in ups APC BX950U-GR BACK UPS 950VA/480W 230V AVR 4 SCHUKO Sockets, it worked immediately and so far after 2 years it has not shown any problems or anything concerning.

Replaced the exact same battery that the UPS had, just with an APC sticker on it, at a cost of 1/3 of the "original."

I replaced the same ones I had from the beginning in the Apc after 5 years. Let's see how long these will last me.

I have had the battery for over a year, let's see how long it will last but the manufacturer says up to 5 years.

I put it in an APC UPS. Works great and is economical from the "mom" (which is another brand with an APC sticker).

I change batteries in many devices at the factory. The only ones that do not have a problem are the CSB and the second ones are the YUASA. Whatever other battery you put in (Sunlight, Ultracell, etc.) you are playing with your luck

2 years and 3 months later, the UPS EATON gave up on me. Its only job was to provide stable power to the router and wireless phone. I will try another one this time...

I got this battery as a replacement for the old battery of an APC Back-UPS 950 line interactive 950VA. The battery works normally, charges, and holds the expected time. I don't know how it will perform over time since it is new, but basically, it is the SAME battery as the factory one (as seen in the photos).

That's exactly where I want to emphasize... you see in the photos that we are talking about the exact same battery, with APC sticking a silver sticker on top... with a price that is double or triple that of this battery.

UPDATE 01/27/2025: The UPS is functioning normally with the battery holding the expected time.

I put this battery in an electric sprayer. Once I tried it, I was very satisfied.

The battery has been installed in the ups since April 2023 and so far everything is good. It lasts exactly 3 years, just like the previous one I had.

Placed in an Eaton UPS, it easily withstands 7-8 years and in the meantime, it responds excellently to power outages

Perfect battery! It came charged at 90%. I bought it to replace the battery in my line interactive APC UPS and it is exactly the same battery as the original one!

I have an APC 950 and from what I can see, it is the factory battery and it lasts a lot and it is not so expensive.

They were the factory ones in this particular case. They lasted for 3 years. They exclusively power 6 security cameras in a business. In a power outage, they can last for four and a half hours.

I bought 2 of these batteries for the ups and I have had them for about 3 months now and so far I haven't had any issues, time will tell....

It was purchased for the APC es700 ups, as a replacement for the original one, which had the APC logo on the sticker. Under the APC sticker, the CSB HR1234W is visible, which costs 25 euros instead of the 55 euros that it is sold with the APC sticker. It worked satisfactorily for over 8 years.
