      The SE450G1 is a smaller standby unit. We do have bigger units that can provide more runtime if needed. Feel free to visit our website www.cyberpowersystems.com for more options. Thank you for your review! CyberPower

    Not impressed. I bought this as a backup for a CPaP in case we had a power outage. The first time, about two months after I bought it, the battery lasted the 6 hours the power was out, however, the next time a year later, it failed completely

      Hello Loomex, This product is not designed for use with medical equipment. We suggest contacting the supplier of your CPAP for suggestions in that regard. Concerning the behavior being presented by the UPS, it may have to do with the internal battery. If you would like more information please reach out to us at 877.297.6937. We hope to hear from you!
