Customer Reviews

Overall rating: 4.9 / 5 from 33 reviews.

This battery truly gives me great peace of mind. It replaces a Duracell battery in my home security system. The other day we had a sudden power outage. I thought the backup battery was dead, but it turned out to be old wiring in my house. Even during the outage, the security system, alarms, and cameras kept running perfectly on this battery. Once the wiring was fixed, it continued working flawlessly.
