Replacement Battery for Lenovo IdeaPad 320 Series

This lithium polymer unit replaces original part numbers L16C2PB2 through L16S2PB2 across IdeaPad 320-15ABR, 320-15AST, 320-15IKBRN, 320-15ISK and V320-17IKB models. It supplies 4100 mAh at 7.6V for 31 Wh of energy. The pack is new and carries a one-year warranty from the manufacturer.

Voltage and Capacity Constraints

The cell chemistry fixes output at 7.6V, so the laptop must accept this exact voltage to operate safely. Capacity is limited to 4100 mAh and cannot be increased without a physically larger pack. Built-in protection circuits guard against short circuit, overheat and overload during charge and discharge cycles.

Polymer Cell Build and Daily Fit

A lithium polymer pouch keeps the profile slim for the internal battery bay of the listed IdeaPad chassis. The black housing matches the original aesthetic and the integrated smart chip manages charging current for longer run time per session. Buyers needing higher watt-hour ratings or a different form factor will not be served by this pack.
