Mighty Max Battery ML7-12, 12 Volt 7.2 AH SLA F1 Terminal Battery, Brand Product, Black (Pack of 1)

I purchased this battery to replace the backup battery in my home’s ONT, which keeps my fiber internet and phone service running during power outages. My original battery had begun triggering low battery alerts and was no longer holding a proper charge, so I needed a compatible 12V 7Ah sealed lead acid replacement with F1 terminals. This unit is a 12V 7Ah SLA battery with F1 spade terminals, and the dimensions matched my original battery exactly. The terminal size and placement were identical, which made it a true drop in replacement for my ONT. If your existing battery is labeled 12V 7Ah with F1 connectors, this should be fully compatible, but I recommend checking the label on your current battery to confirm before ordering. Removing the old battery was very simple. I opened the ONT battery compartment, disconnected the red and black F1 spade connectors, and lifted the old battery out. Installing this one took just a few minutes. The connectors slid onto the terminals securely, and the battery fit neatly into the compartment without any forcing or adjustment. As soon as I connected it, the ONT recognized the new battery and the low battery warning stopped immediately. The system has been operating normally since installation. While I have not yet had a long power outage to fully test runtime, the battery is charging properly and everything appears stable. For anyone needing a standard 12V 7Ah replacement with F1 terminals for an ONT backup system, this has been a reliable and cost effective solution in my experience. Excellent value for the money.

I use these on motorized bicycles,to power head lights,turn signals, etc, these bikes have no charging system, so i have to charge the battery myself, and it's amazing how long this will go without a charge,approximately 2 months, at 30 miles per day,running the lights at all times,great batteries!

This battery is a strong choice for providing reliable power in emergency lighting, alarm systems, or UPS units. I recently used it to replace an aging battery in my backup power setup, and it performed smoothly from day one. The battery is fully sealed, with no leaks or maintenance needed—just set it and forget it. At 7.2 Ah, it’s small enough to fit into tight spaces, but still offers hours of backup time for low-power devices. The terminals are sturdy and accept standard connectors easily, making installation quick and simple. One thing to note: like all lead-acid batteries, it works best when stored in a cool, dry place and charged periodically to maintain peak performance. Also, it’s heavier than lithium options, so expect a bit of heft when handling. Overall, the Mighty Max ML7-12 SLA Battery is a well-built, easy-to-install, and reliable power source. It’s a smart option for anyone needing standby or backup power without fuss or frequent upkeep.

worked, a little high priced

This battery was for my alarm system backup power. It was even cheaper than some of the local stores in my area and delivered fast and I'm in Hawaii! Easy install. Up and running in 10 minutes.

Go quality and long lasting

Battery works well keeps a good charge

I bought one of these Mighty Max Batteries (12V 7.2AH) as a replacement to power my ONT. It worked for a three hour period of time and since my ONT has stopped recharging the rechargeable batteries, I needed additional batteries to rotate in for a full day's use since my internet doesn't work without the battery that doesn't have anything to do with the internet in the ONT. I purchased two additional Mighty Max batteries. I decided to buy one more to be sure I always have one charged and ready to swap in but these weren't available so I purchased the recommended alternate Amazon suggested. That battery has nearly exactly the same specs (12V 7.0AH) and oh my goodness... it lasts for SEVEN HOURS! Same ONT, same charging cables used. So much money and time wasted on these Mighty Max batteries.

Muy buena pila le funcionó muy bien al carro eléctrico de mi hijo

Works great , fits well

Fast delivery. Received within one day of ordering. Solved my problem of low battery in my alarm system. I bought 7a instead of 4a so they last longer while a power outage.

Ayudo a revivir mi UPS, recomendado.
