FAQ about our ARRIS TM822 Cable Modem battery and charger:
Compatible replacement battery vs. OEM originals:
Our Cable Modem batteries are always lower in price and will meet or exceed the
performance of the original ARRIS TM822 Cable Modem 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 TM822 battery is covered by a 3 year limited warranty, far longer than the
warranty on your original ARRIS TM822 Cable Modem battery.
