Replacement battery for Lenovo IdeaPad series

This lithium-ion pack delivers 7.5V and 4000mAh for 30Wh across two cells. It matches part numbers L16C2PB2, L16L2PB2, L16M2PB2 and L17L2PF1 among others. The unit fits IdeaPad 320, 330, 520, S145, V15 and V145 models in 14, 15 and 17 inch chassis. Buyers needing a different voltage or connector layout cannot use this pack.

Sustained discharge and cycle life

Rated for 500 recharge cycles, the chemistry maintains voltage stability during long sessions rather than only brief peaks. Capacity fades gradually with each full cycle, so runtime shortens predictably over months of daily use. The supplier advises an initial conditioning routine: discharge to five percent, then charge and repeat three to four times to wake the cells. Systems that draw unusually high continuous current may see earlier degradation.

Connector compatibility check required

The physical interface varies between production batches, so the plug and cable length must be verified against the original battery before installation. A mismatched connector will prevent the laptop from recognising the pack even if the voltage and capacity are correct. Users who cannot confirm the exact connector type should not order this part. No other electrical or mechanical specifications are provided for cross-referencing.

Questions about this item

Does the 2-cell 30 Wh battery run hot or drain quickly when the laptop is used all day?

The 7.5 V, 4000 mAh Li-ion pack is rated for 500 recharge cycles; normal daily use should not cause excessive heat or rapid drain.

What must I already own for this battery to work in my machine?

You need a compatible Lenovo IdeaPad or V-series model such as the 320-15IKB, 330-14AST or S145-15IWL, and the connector must match the photo.

Will this 7.5 V pack work alongside the original charger and motherboard in an older 320-series laptop?

Yes, it replaces part numbers L16L2PB2, L16M2PB1 and others listed for those models, so the existing charger and motherboard remain compatible.
