  • What buyers say about ExpertPower Replacement Battery for APC Back UPS ES 350

    I was going to throw the APC out, but I thought I would check the prices and see if I could just replace the battery and save some money.

    If it lasts a few years, it will prove to be a good purchase, as the manufacturer name Long and the code 3A 12 volts are helpful in shopping and ensuring you are getting the right model.

    I think the cost of the battery is fair, and more affordable, however if I could have found an original replacement, I would have purchased the original.

    The battery works great in my UPS and the battery meter in the Windows 7 system tray shows the percentage is the same as the original.

    I was happy that it fit into my back up battery, it was the same size as the one I had before, and now my system works again for my desktop computer, monitor and extra HDD.

    Common Questions


    What is the warranty for this product?


    I received a battery that lasted less than two months, so I don't know how you're supposed to contact the manufacturer for a replacement.


    Can you tell what the long beeping means?


    I bought a used Back-UPS es 350 in Goodwill and at first, it wouldn't stop beeping loudly if I turned it on, which is why I bought this battery for.


    Is the height taken from the top of the terminal to the bottom of the battery?


    The measurement from the bottom of the base to the top of the terminal is 2.56 inches, which is the same as the height of the battery.


    What is the difference between F1 and F2 terminals?


    The F2 is larger than the F1 terminal type.


    Will this work in my BE325R that has a dead RBC47 with plastic pieces glue around the metal contacts?


    It worked for me, but you have to be very delicate to fit it into place.
