    I bought this battery to replace the worn out original in my APC Back Ups ES 350. Fit perfectly, is working like a charm so far. Arrived on time. A great value, it adds life to my original Back Ups purchase.

    At the hospital, many of our blood pressure machines use this type of battery. These are priced very well helping us to keep costs down.

    Replacement battery arrived quickly. It fit perfectly in my APC backup. The first night I had installed the battery, the power went out — Perfect timing. It’s the first replacement battery I’ve purchased. I’ll be buying more.

    Good to have a new battery every year or two for my APC 350 so my electronics dont fry. I ordered one similar to this that lasted a few years so time will tell. Other than that looks and works like it should!

    I have ordered replacement batteries from this company before. I will do so again. Each time, the shipping was very fast, and the batteres fit and worked as described. So far, I have only purchased batteries for my battery back-up units. Never a problem. I would like to see some more advice on their site for not only replacing a battery – but upgrading it. If I could buy a better battery, that would fit, I would. I want the best battery I can get for each battery back-up. I’m not sure if any product deserves 5 stars without several months of testing, but since every battery I have received, fit, was easy to install, and worked – 5 Stars. years ago, I threw out back-up units because the cost of replacing the battery were so high. Not any more! I have purchased batteries directly from them, and through . I think buying through is easier, and if there is an issue, would likely be resolved quicker. I have never had a problem, so I will buy more as needed. Again, product was shipped very fast! Pleased with purchase! I’m giving this same review for all my recent purchases from them.

Good shipping on time
Bought this for a 4 wheeler that has set for years. Great purchase as I didn’t want to have to fill a battery with the acid
it came in great, sorry, i do not have a camera, and its working good
My go-to battery supplier for APC backup devices.
Quick swap. Out with the old in with the new
Well packaged, battery looks to be good quality, will install on the weekend and update over time. Got it on Amazon.
Arrived quickly, week package. Week put them to use quickly in Spain.
Love my monster music box and my 1st battery lasted a long time.
Had a Legend battery bought in January of 2024 that went bad wouldn’t start under a load. I have a 2005 Volvo xc90 V8 so the battery cranking is important. Ordered the Mighty Max through Amazon I was overnighted to me , delivered to my doorstep. Recharged all ready to go drop in and start, beautiful! Has a 3 year warranty with options to extend that warranty. How great is that!
The batteries were packaged well, and arrived looking good. Now we need to hook them up.
