If you want to throw your money away, buy this UPS. If you want to have a UPS that will last, buy another one that has replacement batteries available. Moreover, my battery did not last 3 years, as claimed. I had a recent blackout in which the battery died within 2 minutes. Previously, I had enough time to shut down my computer. This time, I didn't.I've very galled that Belkin has the nerve to continue to sell this unsupported product.
