This replacement battery fits ThinkPad Yoga 11e 3rd Gen and Chromebook series notebooks. It matches part numbers 00HW042, 00HW043, 00HW044 and SB10J78990 through SB10J78992. Buyers who need a different voltage or capacity cannot use this unit.

Thermals and power draw

The lithium polymer cell delivers 11.25V and 42Wh capacity with a 3735mAh rating across three cells. Normal charging uses the original laptop charger and the supplier advises recharging at five percent remaining rather than draining to zero.

Installation notes

Visual comparison with the original battery is required because identical laptop models may use different internal battery designs. Connector wire lengths and physical dimensions can vary even when the part number matches, so the battery may not install without verification.

Questions about this item

How do I install the 00HW043 battery in my ThinkPad Yoga 11e 3rd Gen, and what step often gets missed?

Power off the laptop, disconnect the AC adapter, remove the base screws, detach the old battery connector, fit the new 3-cell pack, reconnect the cable securely, replace the cover and screws, then charge fully before first use.

What maintenance or replacement will the 11.25 V 42 Wh lithium-polymer pack need later?

Expect gradual capacity loss after several hundred charge cycles; when run-time drops below your needs, replace with another 00HW043 or compatible 00HW042, 00HW044 pack.

What limit appears first during sustained use of this 3735 mAh battery?

The 42 Wh capacity sets the runtime ceiling; under continuous load the pack will deplete to the 5 % low-level warning before thermal or voltage limits are reached.
