Perfect Replacement Battery for My ONT
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.

Trustworthy Seller!
The 5 star is for customer service. The battery malfunctioned about 7 months after purchase. My home security alarm panel was showing low battery warnings. I reached out to the seller and confirmed that it was still under warranty. The seller promptly responded and sent out a replacement battery. Very impressed with the seller!

Good battery
I ordered the battery for my grandson's toy truck but it didn't work, I think there is something with the starter broken so I will work on that next.
