Acer AP19B8K Replacement Battery Review

Acer AP19B8K replacement battery, an 11.4V 42Wh three-cell pack for the Aspire 3 A315-24P and A315-59 currently in our laptop catalog.

A315-59 listings show 43.08Wh against the 42Wh figure here, a gap small enough to be rounding rather than a real capacity split between the two chassis.

What to check before you buy

Both Aspire 3 chassis share this pack across their Ryzen and Intel configurations. Confirm the AP19B8K or AP19B5K code on your existing battery before ordering.

Aspire 3 A315-56

The A315-56 was built with three different packs (AP16M5J, AP19B8K, AP18C8K), so read the code on your old battery first.
