Compatible Replacement for Acer AO751h-1545

The part suits anyone whose Acer AO751h-1545 loses date, time or CMOS configuration after shutdown. It is not a main laptop battery and will not power the system for portable use. Buyers who need a primary power source or a different form factor should look elsewhere.
