Compatible ThinkPad Models

This replacement battery fits ThinkPad P15s Gen 1, P15s Gen 2, P53s, T15 Gen 1, T15 Gen 2 and T590 systems. It replaces OEM part numbers 02DL011, 02DL012, L18M3P71, L20D3P71 and related service numbers. The three-cell lithium-ion pack delivers 11.52V and 4950mAh capacity. It is a new unit supplied by PowerWarehouse.

Verify Your Part Number

Before ordering, confirm the exact part number printed on your original battery or in the laptop service manual. Match it against the listed OEM numbers such as 5B10W51823, SB10W51931 or L18L3P71. Ensure your specific model suffix (for example 20T4, 20W6 or 20N4) appears in the compatibility list. This avoids receiving a pack that will not seat or communicate correctly.

Ideal For Direct Replacement

Suits owners needing a like-for-like swap for a worn or failed internal pack in the listed ThinkPad models. Buyers who want more storage or a higher-capacity extended-life option should look at something else, as this unit matches the original 4950mAh specification. It is not a charger or AC adapter, so users requiring a power brick must purchase that separately.

Questions about this item

Does the PowerWarehouse L18M3P71 battery ship with any tools or cables, or must I buy them separately?

The battery is supplied as a standalone unit; no screwdrivers, cables or mounting hardware are included in the package.

My ThinkPad T15 Gen 1 shows part number 5B10W51823 on the old battery — is this the correct replacement?

Yes, 5B10W51823 is listed among the compatible OEM part numbers, so the L18M3P71 will fit your T15 Gen 1.

What runtime can I expect from the 11.52 V, 4950 mAh rating once the battery is installed in my P15s Gen 1?

The 57 Wh capacity typically delivers several hours of mixed office work, though actual runtime varies with screen brightness, workload and power settings.
