Mighty Max BatteryML5-12 - 12 Volt 5 AH, F1 Terminal, Rechargeable SLA AGM Battery

The battery in my garage door died. I have only owned the home for 16 months and I didn't know when the garage door lift had been installed. It was beeping 4 times each time the door was raised. I totally forgot that a battery was located on the inside. I had this happen some years ago when living in Florida. Paid a garage door company to come out and replace the battery. I believe I paid between $100 and $150 for the battery and service call. I purchased this battery on Amazon for $20. Installed it, reprogrammed all my door open controls and everything is working great!!!

This was a perfect replacement for my DGD852 (Linear) garage door opener. After several weeks of hearing the 4 beeps telling me I needed to replace the battery, I finally broke down and got it done. It was so easy! The new battery works perfectly- it was surprisingly heavy but fit just right. I took a pic of the old battery sitting on top of the box for the new battery.

In times of need this battery is useful for the mechanism of garage door.For power electric garage doors battery replacement, I order 2 just in case I was satisfied with the results, longevity 2 years.

Easy install just “plug n play”.Don’t know the longevity.

Bought these a year ago to replace the batteries in my garage door openers. After ~7 years, the original batteries were done for. A year in and these are working just fine, hope they can last as long as the originals.

First, APC's "official" UPS SLA batteries are trash now. They seem to go with lowest-bid battery companies out of China. I went official for my larger fairly high-end SmartUPS and paid a lot, and the battery died in about 10 months. The UPS started rejecting it. I eventually just bought a cheapo battery for 1/4 the price and it's lasted at least as long as the official one.SO, with that said, onto the Mighty Max battery. This battery is sold by a real company (not a random collection of letters posing as a brand) and I get the feeling like they care a bit about their reputation. I've purchased multiple Mighty Max batteries and they seem reasonable. They are relatively inexpensive and hold up pretty well. When my old little UPS I use for my PC finally started rejecting its battery, I bought this one and so far it seems to work fine. No frills, nothing special about it. It's just a decent battery for a decent price. As such, it's miles ahead of where APC is right now.

Replacement battery for my alarm system. I’ve used the same brand in my motorcycle and have been pleased with the life of the battery.

Revived my old B&D Radio. I use this during any Severe Weather Alerts. Perfect fit. It should last for several years...
