2-Power hoofaccupack Lenovo ThinkPad X13 Gen 1 X390 - batterij - 44 mAh (2P-02DL018)

When a laptop is expected to keep up with a full day of meetings, travel, and remote work, the original battery often becomes the weakest link. This 2-Power Main Battery Pack steps in as a direct replacement for the Lenovo ThinkPad X13 Gen 1 and X390, restoring the endurance your device had on day one. It delivers 44Wh of energy from a 3-cell lithium-ion design, matching the original 11.4V output and fitting internally without altering the laptop's slim profile. Unlike generic aftermarket options, every protection circuit is built in: overcharge, over-discharge, overcurrent, short-circuit, and over-temperature safeguards keep both the battery and the ThinkPad safe during daily use.

Highlights

• 44Wh capacity and 11.4V voltage match Lenovo's original specifications
• 3-cell lithium-ion construction for reliable, long-lasting charge cycles
• Rechargeable design with no memory effect – top up anytime
• Built-in protection against overcharge, over-discharge, overcurrent, short-circuit, and overheating
• Compatible with ThinkPad X13 Gen 1 and X390 series laptops
• Equivalent to Lenovo part numbers L18M3P71, L18L3P71, and L18C3P71
• CE, RoHS, and FCC certified for safety and environmental compliance

In daily use

Installation is straightforward for anyone comfortable removing the bottom cover of a ThinkPad – no special tools beyond a small Phillips screwdriver are required. Once fitted, the battery charges normally via the laptop's standard USB-C or slim-tip adapter. Users can expect runtime close to the original factory pack, typically 6–9 hours depending on workload, screen brightness, and power settings. The black casing blends invisibly with the laptop's chassis, and because it is a genuine replacement-grade cell pack, the ThinkPad's battery health reporting and charge limiting features continue to work as expected.
