2-power Main Battery Pack Lenovo ThinkPad E15 Gen 2 - Batterie - 45 mAh (2P-5B10X02594)

This 2-POWER main battery pack restores the Lenovo ThinkPad E15 Gen 2 to full mobility with a fresh 45 Wh lithium-ion cell. Unlike generic replacements that often arrive with mismatched connectors or weak charge retention, this pack is built to the exact FRU specifications of the original Lenovo battery (L19C3PF0, L19M3PF0, L19L3PF0, 5B10W13900, 5B10W13901), ensuring a precise fit and reliable communication with the laptop's power management system. It is a true internal battery, not an external power bank, so it sits flush inside the chassis and maintains the ThinkPad's slim profile.

Highlights

• Genuine 45 Wh capacity with 11.52 V output and 3900 mAh equivalent energy for long runtimes.
• 3-cell lithium-ion construction with integrated protection against overcharge, over-discharge, overcurrent, short-circuit, and temperature extremes.
• Black colour matches the original component; no visible difference after installation.
• CE, RoHS, and FCC certified for safety and environmental compliance.
• 12-month warranty covers manufacturing defects and premature capacity loss.

In daily use

After installing this battery, the ThinkPad E15 Gen 2 will report accurate charge percentages and estimated runtimes, just like with the factory unit. The battery charges via the laptop's standard USB-C or AC adapter—no special charger required. Because it is an internal component, professional installation is recommended; however, experienced users with the correct tools can replace it by following Lenovo's service manual. The battery is rechargeable and designed for hundreds of charge cycles while maintaining at least 80% of original capacity under normal use.
