5B11M90130 54.7Wh 15.6V 4-Cell Li-ion Battery for Lenovo ThinkPad L13 Gen 6 S2 Gen 10 2-in-1 Replaces L24D4P72 L24N4P71 Grade A Cells

Why You Need a Genuine 54.7W h Battery for Your ThinkPad L13 or S2 Gen 10

Your Lenovo ThinkPad L13 Gen 6 or S2 Gen 10 2in1 is a versatile workhorse for business, school, or creative work. But even the best batteries degrade after a couple of years shorter runtime, sudden shutdowns, or swelling. Worse, many compatible batteries online are fakes: they advertise 54.7W h but actually contain 41Wh cells. Your laptop runs for less time, and youve been cheated.

This L24M4P72 battery is different. We deliver a true 54.7W h / 3510mAh capacity using brand new Grade A Liion cells. What you see is what you get.

CRITICAL Two Battery Capacities Exist for These Models

Capacity Battery Model Numbers
High Capacity ( 54.7W h) THIS ONE L24N4P71 / L24M4P72 / L24D4P72
Low Capacity (41Wh) NOT THIS L24D3P7A / L24C3P74
Before ordering, please open the back cover of your laptop and physically check the battery model number printed on your original battery. Installing the wrong capacity will cause fitment or performance issues.
