Replacement battery for Acer Chromebook Spin 311

This new lithium polymer battery delivers 7.5V and 36.5Wh capacity for the Acer Chromebook Spin 311 Convertible CP311-2H-C679 series. It replaces part number AP16L8J and offers plug-and-play installation. The 4865mAh cell restores mobile runtime for students and mobile professionals who need reliable power away from a desk.

Verify the original battery part number before

Open the back case of the laptop and confirm the existing battery reads AP16L8J to ensure compatibility. The supplier notes that not all compatible models are listed, so matching the physical part number is essential. Check the connector layout against the product image before purchase. Read the manual carefully before fitting the replacement unit.

Lithium polymer chemistry runs cool

The battery produces no fan noise and adds negligible heat during normal charging and discharging cycles. Condition the new cell by discharging to 5 percent then charging to 95 percent for three to four cycles. Store at over 80 percent charge if removed for longer than one month. Avoid leaving the AC adapter connected continuously while using the battery.
