Questions about this item

Does the 3.91 V 26.7 Wh lithium-ion cell run hot during a full day of tablet use?

The 2-cell lithium-ion pack operates at 3.91 V and 26.7 Wh; it is designed for stable current and low self-discharge, so heat stays within normal tablet limits during extended use.

What must I already own to install this GreenTech L23D2P31 battery?

You need a compatible Lenovo Tab B11, M11, K11, TB330FU, TB330XU or ZAD-series tablet and basic tools to open the case and disconnect the old pack.

Will the 4820 mAh replacement work alongside the original charging circuit in my older Lenovo Tab?

Yes — the battery matches the OEM voltage of 3.91 V and capacity of 26.7 Wh, so the tablet's existing charger and power management recognise it without modification.
