  • Delivers 39.04 Wh capacity at 7.7 V for extended runtime
  • Lithium-ion cell rated for up to 500 recharge cycles over its life

Replacement battery for Samsung Chromebook

This lithium-ion battery replaces the original EB-BW720ABE and EB-BW720ABA packs used in Samsung Chromebook Plus V2 models such as XE310XBA and XE350XBA, plus Galaxy Book 12 variants including SM-W720, SM-W723 and SM-W727V. It matches the 7.7V voltage and 39.04Wh capacity specified for those devices. Buyers needing a different voltage or form factor cannot use this unit.

Build quality and daily fit

The pack is built to the same physical profile as the factory battery, so it seats in the existing compartment without adapters or case modifications. Integrated protection circuits guard against short circuit, overheating and overcharge, while the smart control chip manages charge current for stable operation. Users who require hot-swap capability or external charging contacts will not find those features here.

Practical limits of lithium-ion chemistry

Rated for up to 500 recharge cycles over the life of the battery, capacity will gradually decline with age and temperature exposure. The 7.7V nominal output is fixed by the cell chemistry and cannot be altered for other platforms. Systems that demand a higher watt-hour rating or a different connector key will remain incompatible.
