Interstate Batteries 12V 8Ah Battery (SLA1075) Sealed Lead Acid Rechargeable SLA AGM (F1 Terminal) Wireless Internet UPS Systems, FIOS, SP12-7

I have connected this replacement battery to an old CyberPower 525SL UPS and it has worked flawlessly now for a few months - We have had several power outages, which is often the case in my area, and this battery has certainly paid for itself. Well recommended.

I'm so glad I was able to purchase these batteries for my mom's stairlift. No issues thus far.

This is a great savings for anyone with a security system. These batteries sell for over $40.00 normally and you need to drive to larger cities to buy them. Very happy with purchase & savings.

The battery arrived in four days - three days before the ETA. That was nice. The battery itself seems sound. Of course, as with any battery, longevity and service life is a big factor in the value of the item. This Interstate battery was priced below the competition in my search. I typically get 3 to 4 years of service from these 12V 8Ah batteries. Time will tell if the lower price translates into value.

The red light on my Verizon FIOS unit came in early November. The red light indicated that the backup for the phone during power outages would not work. The instructions on the Verizon website said that any 12-volt 7.2Ah SLA (Sealed Lead Acid) battery would work. I looked at lithium batteries with the same power and size, but there were no reviews reporting using them with Verizon FIOS, so I went with the safe choice, selecting this Interstate Lead Pack. The battery has been installed for a month and working fine. How long it will last is not known at this point. The only difficulty was getting the old battery out. To release, one had to press two levels on the side of the old battery; they were extremely tight. I had to use two large screwdrivers to force the levels to release the battery. Update: January 2024. I had an 8 hour power outage and was able to use my FIOS phone line throughout on the backup power from this battery.
