Check your current part number before ordering

Verify the part number printed on your existing battery matches one of the listed replacements. The three variants L18M3P71 L18L3P71 L18S3P71 are cross-compatible but ship with different voltage ratings. Confirm your laptop model appears in the supported list such as ThinkPad T590 Type 20N5 P53s Type 20N6 or T15 Gen 1 Type 20S6 20S7.

Upgrades a depleted or failing original pack

If your original battery no longer holds charge or shows swelling this restores full runtime. The 51Wh capacity matches the factory specification so runtime returns to as-new levels. It is not a higher-capacity upgrade and will not extend usage beyond the original design. Buyers needing longer unplugged time should look for an extended-capacity pack instead.

Questions about this item

Does the package include the battery only, or are tools and screws supplied for installation?

The battery ships as a single unit. No screwdrivers, opening tools or mounting screws are included, so keep the hardware from your original battery or source it separately.

The listing shows three part numbers — L18M3P71, L18L3P71 and L18S3P71 — with different voltages. Which one should I choose?

All three are interchangeable for the ThinkPad T590, P53s and T15 Gen 1 series. The supplier will send whichever is in stock at 11.52V, 11.55V or 11.58V.

What does the 51Wh rating actually deliver in a ThinkPad T590 or P53s under normal use?

It restores the original 51Wh capacity, giving roughly the same runtime you had when the laptop was new — typically several hours of office work per full charge.
