    This is the second battery backup I have had. This product saved my computer from a power surge, so I had to buy another. Can't beat the value for the price

    Alarm

    No way to disable alarm

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    There is no way to disable the alarm on the unit. If it is in your bedroom, be prepared for frequent loud beeps and buzzes all night even if your computer is off. More expensive models such as BACK-UPS ES are compatible with an APC software called powerchute that allows you to modify or disable alarms. I would only buy such a model.

      Thank you for taking the time to review the BN4001. The BN4001 is intended to protect networking equipment ( modem, router etc) and not a PC and so it does not come bundled with management software and a USB cable. The software may be used to disable to the On Battery alarm. Please contact our support team for further assistance and we will walk you through downloading the software, help you obtain a USB cable and explain how to disable the On Battery alarm.APC

    I was expecting more. This product didn't always keep my PC running during power surges. Now after a year or so, it needs a battery replacement.

    No way to silence beep - I am returning it

    Posted .
    This reviewer received promo considerations or sweepstakes entry for writing a review.

    Unlike other UPS systems, this does not provide a way to disable the beep, so there will be a loud irritating beep every few seconds while operating on battery. That makes it unusable for me, so I am returning it.

      Thank you for taking the time to review our BN4001. We appreciate the feedback and apologize that the unit did not meet your exact needs. Although you cannot silence the on battery alarm, we may be able to adjust some settings, so it does not transfer to battery as often. Please contact an APCbySchneider support team at your earliest convenience for assistance with this. APC

    This APC worked well for about 2 years but now it doesn't hold a charge at all. If the power goes out, the unit shuts off completely. Disappointing quality.

    This battery wont last long, it gives you maybe 20min maximum to work on your PC, just to save files and turn off your system !
