Replacement Battery for APC Back UPS ES 350

worked great

I purchased this battery to use with my APC ES 350 UPS unit. Thus far, I'm very pleased with it. It charges quickly and seems to provide ample back-up power for my purposes. It's packaged well, is easy to install, and appears to be quite well made. Zero complaints thus far.

Fits as intended ... hopefully works as well as last one.

This is a cheaper replacement for a failed APC battery than the APC branded one. All of the specs are the same, and the terminals are in the right spot. They last several years, so it’s an easy investment. Time will tell how long this will last:

The original batteries in a couple of APC uninterruptible power supply (UPS) units I had eventually wore out and wouldn't keep things powered up more than about two minutes. These were easy drop-in replacements for the original batteries, and now the UPS units can run a PC or switch for about a half-hour again.

Replaced my manufacturers battery that finally died in my apc ups. No more beeping and seems to be charging just fine. Much cheaper than replacing the whole ups and better for the planet

This battery arrived DOA and the manufacturer refused to provide a replacement and told me to go to Amazon, and Amazon told me to go to the manufacturer. I will not be buying from this manufacturer again.

bought this battery to replace the battery in a cyber-power U.P.S. at less than $20 it worked great. interestingly, it was rated the same 3.5 amps as my old battery, but 1/3 larger. either the old battery was over-rated, or this one is under-rated. remember, how LONG a U.P.S. will work is dependent on the size of the battery. a 3.5 amp battery provides a total of 40 watts (for 1 hour). so if the item you are protecting draws that, you will get 1 hr of protection MAXIMUM. 400 watt load, 1/10 of that (6 minutes!). mine protected a router, modem, and wire-less phone. it was probably too-small to really do that job. i have since replaced it with a larger U.P.S. (with a 9 amp battery, providing 100 watts of total power (2 and 1/2 times the power of my original U.P.S.), and re-purposed my old U.P.S. to protect a single Tivo box (1 amp draw=120 watts=20 minutes of back up MAXIMUM. most U.P.S.'s are over-sold, and can't produce nearly the protection they advertise.

Perfect fit. No issue with the product and the price is right.

Works, does the job.

Plugged it in and it works perfectly. I am very happy with the purchase. So far, so good. I recommend this battery as a replacement.

no review it works

Good quality battery that works well
