Acer AP21A8T Replacement Battery Review
Acer AP21A8T replacement battery, a 15.4V 90.61Wh four-cell pack shared across the Nitro 16 AN16-41 and the Predator Helios 18 and Helios Neo 16 gaming chassis.
One battery family covers three of our catalog's Acer gaming laptops. AP21A7T and AP21A5T are the same physical pack sold under sibling codes.
What to check before you buy
This shared 16 to 18 inch Predator/Nitro chassis platform uses several AP21A-prefixed codes interchangeably. Match any of AP21A8T, AP21A7T or AP21A5T against your existing pack.
