FAQ about our ECS Advent 7091 CMOS/BIOS battery and charger:
Compatible replacement battery vs. OEM originals:
Our CMOS/BIOS batteries are always lower in price and will meet or exceed the
performance of the original ECS Advent 7091 CMOS/BIOS 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 Advent 7091 battery is covered by a 3 year limited warranty, far longer than the
warranty on your original ECS Advent 7091 CMOS/BIOS battery.
