Replacement Battery for Galaxy Book 12.0

This 7.7 V lithium-polymer pack delivers 39 Wh of capacity for Samsung Galaxy Book 12.0 models including the SM-W720, SM-W723, SM-W727 and SM-W728 series. It also fits Chromebook Plus V2 XE520 and XE521 devices. The battery replaces original part numbers EB-BW720ABA, EB-BW720ABE, AA-PBMN2HO and AA-PBMN2H0.

Capacity and Voltage Limits

The fixed 39 Wh rating and 7.7 V output define the energy available per charge cycle. Runtime will vary with screen brightness, workload and system power management, so heavy workloads will drain the pack faster than light browsing. No higher-capacity version is offered in this form factor.

Upgrading from a Degraded Original

This unit replaces a factory battery that no longer holds a useful charge or has swollen. The jump is worth it when the original cell drops below roughly half its initial runtime or triggers replacement warnings. It is not for users who need extended runtime beyond the original 39 Wh specification.
