Uplus 12V 5Ah Rechargeable Sealed Lead Acid Battery - DJW12-5.0T Replaces Home Alarm Battery Compatible with F1 F2 Terminals for Garage Doors, Security Systems, Burglar Alarms

Worked great as replacement batteries for my Liftmaster gate. Came with adapters for the terminals that fit great. Installation was simple and much cheaper than having a technician come out.

Perfect fit for my battery backup. Came with some clips to meet situations where a different connector size is needed. So far it is holding a charge and working as expected but time is the real tell-tail determination of the products quality.

This battery was the perfect replacement battery for a black and decker portable power station that was in need of a new battery. The size was an exact fit and easy to install and was 100% compatible. Now my power station is back to 100% functionality.

Best battery for the money. Solid even in cold temperatures. Using this on a generator.

I purchased two of these to replace the batteries in my APS SmartUPS . Perfect size and capacity. Unsure yet how they will endure - I've only had them for a week. Currently working great. I did have to move the connectors from the old batteries to these.

Arrived 8/29/25, manufactured 1/25/25. I put in on my Noco 1amp maintainer & was topped up in less than 2 hours. Battery came very well packaged in double wall cardboard box with Styrofoam end caps. Even had little rubber covers on the terminals. The original battery was 17Ah, this one is 18Ah, so this has a little more power than original. It's AGM, so battery life should last through many cycles. The charger included in the FatMax is not a maintainer, it is a trickle charger, so you can't leave it plugged in all the time or it will overcharge & degrade the battery. I've read many negative reviews for this type of battery, I think the cause of early failure is leaving the jump box plugged in. The instruction manual specifically says unplug when fully charged & recharge every 30 days, what a pain, right? But that's how these things work. Overall an easy install, perfect fit right down to terminal type. Bolts & nuts were included with washers & lock washers, but I used the original flanged bolts & nuts. Very durable design, compatible with the FatMax. Time will tell how long it lasts, if it fails early, I'll update this review. I just have to remember to plug it in every month.

Ordered battery to replace generator battery with on board charger, installed battery around April 2025 and never plugged in the actual charger(on the generator). Went out to generator to get ready for winter in November fully expecting battery to not work at all since I did no maintenance on it. Generator fired right up like I had just installed the battery. Highly impressed with just that!

Battery went bad for the generator, it's over 10 years old, hardly use it and forgot to put battery on a maintainer. The H07551 and some other Firman generators use part # 357713553 for the battery. This one is an exact fit and has more power (18Ah vs 15Ah) than the original battery. Battery arrived well packed/padded. It comes with replacement screws/nuts/washers too. Easy to replace. Now just need to keep it on a maintainer, HF sells a decent one (sku 59000).
