FAQ about our ADT 823990 Alarm System battery and charger:
Compatible replacement battery vs. OEM originals:
Our Alarm Systems batteries are always lower in price and will meet or exceed the
performance of the original ADT 823990 Alarm System battery. Batteries can sometimes
even contain identical battery cells
as the OEM original did, but lacking the brand name, can be offered at a discount prices.
Our 823990 battery is covered by a 3 year limited warranty, far longer than the
warranty on your original ADT 823990 Alarm System battery.
What is your return policy on batteries and battery chargers?
