Excellent

It works perfectly. The alarm company wanted to charge me 25.00 plus service charge. Rep told me I could get battery and replace myself. I did and saved money .

New house alarm battery replacement.

Ordering was easy, delivery of the correct battery as ordered, was very efficient (faster than expected). Installation by self was easy, and unit charged up as expected, and low battery message cleared as expected within 24- hours.
