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

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.Ali Julia reviewReview of Interstate Batteries 12V 8Ah Battery Sealed Lead Acid Rechargeable Battery

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.

Perfect fit and matching power requirements.Working great

Purchased to replace the battery in my home security system. Easy to install and its doing the job. Cannot comment on longevity or value yet as its only been in place a few months but so far it looks good.

It works with my alarm system for my house

This battery arrived fairly quickly and was very well packaged. Unfortunately, upon opening the package and unwrapping the battery, I saw that the positive terminal was heavily corroded (please see the 2 pictures). I was very--and unpleasantly--surprised. It looks as though it had been heavily used, in a humid environment, but the good quality of the packaging suggests that it could been a new battery that was sitting on the shelf for quite a long time. This item is not returnable; however, Amazon was terrific (as Amazon usually is) on refunding. That noted, I now have a piece of hazardous junk (it is a lead acid battery) that needs proper disposal. Assuming this was not a used battery, I hope Amazon can establish better inventory control processes for items like this that have short shelf lives.

Fits my backup battery that back ups my computer, modem, router, and scanner. If there's bad weather, and I lose power. I can still charge my phone, and shutdown my computer without ruining my work.

Interstate batteries work great. I use these on my security gate and they usually last about a year or two.
