Amazon Basics UPS Battery Backup & Surge Protector 800VA/450W, 12 Outlets, Standby Uninterruptible Power Supply, for Power Outage Protection, Compact, Black

The battery backup works fine, and the software gives a pretty good review of its performance. I'm very disappointed that Amazon doesn't offer a replacement for the battery. Of all the batteries Amazon carries, it doesn't offer a replacement battery for its own product. Wouldn't that make sense? These batteries have a short lifespan. Can someone at Amazon tell me where to find a replacement battery?As a follow up to the above review: Since I couldn't find an exact replacement for the battery in my old UPS; I took a gamble and ordered the NPP NP12-5AH battery, also from Amazon. Worked Like A Charm. It fit perfectly in the small battery compartment, charged up real nice, and has my older 600VA running like new. It was also a very reasonable replacement cost wise. Don't let the low cost and country of origin deter you. This is a quality product and I'm lucky to have found it.

Our neighborhood is actively in development. With this, the power gets cut off way too often. We work from home and don’t want to have to keep connecting to a hot spot, so this keeps our WiFi on for hours!!! We also got another for our baby camera that’s connected via WiFi. It’s kept them on!!I recommended them to friends in the neighborhood and now 5 of my friends have them.

This works well for my home’s small telecom cabinet “server room.” I have AC adaptors for a cable modem, WiFi router, and VOIP phone unit plugged into the three uninterruptible power supply outlets. I plugged a PoE injector, landline phone, and family cellphone charging station into the non-UPS outlets. This keeps the critical loads running during occasional power outage blips lasting a few seconds. Such interruptions are not acceptable during work-related videoconference calls! This is not a “pure sine wave” inverter but these AC adaptor loads don’t benefit from a pure sine wave.I purchased another one of these four years before today. The battery reached the end of its life not long ago. No common, consumer grade lead-acid battery will last more than 4-5 years. I purchased a replacement unit, and also I replaced the battery in the old unit. The battery is model DJW12-2.9 and available on Amazon, for sale at less than half the cost of a new unit. I’m certain a nearby battery store chain sells this battery too (just bring in the old one). I’m using the old unit with newly purchased battery elsewhere in the home, and I set a reminder on my phone for 3 years from now to test both UPS batteries. Good compact product.

We installed a WiFi network at my place of business and were looking for multiple UPS's for each of our switches and WiFi Access Points. When looking for what device would work best I came across this Amazon Branded piece of equipment. The price was fair and I really like their, "Backed by an AmazonBasics limited 1-year warranty, including the battery; $75,000 connected equipment guarantee" - the last bullet in the description.This warranty is a joke. We had a power surge in our building and most of the UPS's worked as intended, however there was 1 that did not. All the equipment connected to it was fried after the surge and no longer works. Over $900.00 of equipment was destroyed (all of which was ordered from Amazon). I just wanted a credit I could, gift card, something! I had serial numbers and images of the equipment and everything. I immediately contacted customer support and told them that I wanted to submit an issue/claim under the "Backed by an AmazonBasics limited 1-year warranty, including the battery; $75,000 connected equipment guarantee."I had to continue to reach back out to Amazon Customer Support 3+ times, each time they told me someone would follow up with me within the next 3-5 business days on my warranty claim. I spent a total of 4-5 hours (spread out over multiple days) of my time emailing, chatting over the phone, sending pictures, chatting online and still nothing has happened. I have continually been ignored and have been given false promises of, "I will PERSONALLY call you back on (x) date to follow up with you on this issue." Then, after no phone call or follow-up, I would email them back, only to have a different person respond and tell me to call Amazon Customer Support (which means I would start from scratch and have to tell my story all over again and go through the same steps). The continuous false promises and disregard (whether intentional or not) is beyond frustrating - especially when you buy the device because of the warranty that is promised.I am a regular user of Amazon services, but I'm very disappointed with the way this situation was handled and I feel that I have wasted my time and have been ignored multiple times.Not a product I would recommend buying.

This battery backup works for short-term power outages and surge protection. The audible beeps can be annoying, so in my opinion, that leaves room for improvement. The footprint is small enough to be out of the way, but like most battery solutions, this thing is heavy for its size. The overall design is good, and it was easy to install. I like it.

After 3 months of use, I am happy to report this battery backup is working great. Where I live in Florida, power is frequently interrupted, sometimes a quick second or two, sometimes longer. So far this UPS has provided uninterrupted power which I truly appreciate.

At the 5 year mark, it started acting flaky. At the 62 month mark it started randomly dying, taking down the computer and everything else plugged into the battery + surge protector side. That got annoying, so I needed to replace it - should have just replaced the battery, but I forgot in the intervening time that it was replaceable.Given the price I paid initially, I thought this was an excellent value.
