Replacement battery for Samsung Chromebook models

The PISKEKAT EB-BW720ABA is a brand new laptop battery rated at 7.7V with a capacity of 39Wh and 5070mAh. It replaces original part numbers EB-BW720ABE, AA-PBMN2H0, GH43-04690A and GH43-04691A. The unit is designed for owners of Samsung Chromebook 4 11.6 inch XE310XBA variants, Chromebook 4 Plus 15.6 inch XE350XBA variants and Chromebook Plus V2 12.2 inch XE520QAB and XE521QAB models.

Direct-fit replacement restores original runtime

Installing this battery restores the factory voltage and capacity without requiring adapters or firmware changes. The matching part numbers ensure the connector and cell layout align with the chassis, so the Chromebook recognises the pack immediately. No additional software, drivers or calibration tools are bundled; the improvement comes solely from replacing a worn cell with a fresh 39Wh unit.

39Wh capacity suits light daily workloads

A 39Wh pack typically powers web browsing, document editing and video playback for several hours on supported Chromebooks. Heavier multi-tasking, sustained high brightness or continuous video conferencing will drain the charge faster, requiring a recharge before a full workday ends. Users who need all-day operation away from a socket should plan for midday charging or a portable power bank.

Questions about this item

Does the 39 Wh EB-BW720ABA battery need any periodic calibration or maintenance?

No routine calibration is required; the lithium-ion pack is maintenance-free for its service life.

What limits runtime when the battery is used continuously at full load?

The 39 Wh capacity sets the energy ceiling, so sustained high draw depletes the 5070 mAh charge fastest.

Does the 7.7 V pack run hot or draw extra power during all-day use?

Normal operation stays cool; the cell chemistry handles continuous discharge without excess heat or parasitic draw.
