GEILIENERGY 300-03866 Backup Battery for Honeywell Lynx Touch 5100, Lynx 5200, Lynx 5210, Lynx Touch 7000, LYNXRCHKIT-SHA, JJJ WALYNX-RCHB-SHA ADT Ademco System(1 Pack)

Worked perfectly. Saved a trip from alarm people.

Besides the fact that the battery did not fit my system like they claimed it would, the batteries came CUT! the port to insert into the alarm system wasnt even there! and no, it did not get cut upon opening (it was sent in a box and no sharp objects were used to open). DO NOT PURCHASE THIS PRODUCT FROM THIS SELLER!

Very easy to install.

The alarm keeps showing Low Battery, I returned the first one for the same reason.

it never worked. seems the battery was DOA.

We moved into a new house with an existing security system and the tablet kept chirping at us that the battery was low. These batteries are almost impossible to find at Lowes and Home Depot so I was super glad I found it on Amazon! Super easy to install and the machine stopped yelling at us.

Just as described, good price.

ease of installation

Good price fast ship

Bought for my alarm system because the low battery chime was going off. I installed it and the chime is still going off and says low battery.??? Is it the battery? Who knows
