Which should you buy, AP18C8K Replacement Battery or AP18E8M Replacement Battery?
Buy the AP18C8K Replacement Battery for Chromebook 315 CB315-3H and CB315-3HT battery replacements, though it is not built for anyone matching on the Aspire series name alone. It also earns its place with aspire 5 A515-54, A515-55 and A515-58M owners whose old pack reads AP18C8K or AP18C4K. Avoid it for aspire 3 A315-56 units fitted with an AP16M5J or AP19B8K pack. Take the AP18E8M Replacement Battery for nitro 5 AN515-55 and AN515-57 owners whose old pack reads AP18E8M or AP18D8M. It is the wrong buy for nitro 5 AN515-55 units fitted with the 58.75Wh AP18E7M, unless you accept the small capacity drop.
