Replacement Battery for ThinkPad T14s Gen 2

This GreenTech 4-cell lithium-ion unit delivers 15.36V and 54Wh to compatible ThinkPad T14s Gen 2 models. It is built for owners who need a direct swap when the original pack no longer holds charge. The black casing matches the laptop chassis and fits the internal bay without modification.

Replaces Multiple Lenovo Part Numbers

The battery covers OEM references L20M4P72, L20D4P72, L20L4P72, L20C4P72, 5B10W13976, 5B10W51814, 5B10W51815, 5B10W51816 and the SB10W51914 through SB10W51917 series. It is the correct choice when your service manual lists any of those part numbers. It is not for users whose ThinkPad requires a different voltage, cell count or form factor.

54Wh Capacity with 3711mAh Rating

The pack provides 54 watt-hours at 15.36 volts, yielding 3711 milliampere-hours of stored energy. That capacity supports typical office workloads and web browsing for several hours on a single charge. Runtime falls sharply under sustained heavy CPU or GPU loads, so users running continuous compile jobs or video rendering should keep the AC adapter close.

Questions about this item

What are the exact dimensions of the L20M4P72 battery so I can confirm it fits my ThinkPad T14s Gen 2?

The battery measures 10.65 x 3.65 x 0.35 inches, matching the internal bay of the ThinkPad T14s Gen 2 models listed.

Which screw or latch step is most often missed when swapping this 4-cell pack?

After removing the bottom case screws, the internal battery connector must be unplugged before lifting the old pack; skipping this disconnection risks cable damage.

When will the L20M4P72 need replacement under normal use?

The 54 Wh lithium-ion pack is rated for 6 months of replacement coverage; capacity fade after that period varies with charge habits and temperature.
