Direct replacement for Lenovo Chromebooks

The KingSener L18D3PG1 is a new lithium-ion battery built to match the original specifications for Lenovo 100E, 300E and 500E Chromebook second-generation models. It delivers a rated capacity of 3735mAh and 42WH at 11.25V. The part-number list includes L17M3PB0, L17L3PB0, L17C3PG0 and multiple Lenovo service codes so you can verify exact compatibility before purchase.

Stable voltage and safe operation

High-quality cells and a matched protection circuit maintain the rated 11.25V output without inflated capacity claims. Normal use stays within the thermal limits of the original design, and the supplier advises a full charge-and-discharge cycle two or three times at low current to condition the pack. Avoiding continuous adapter connection while on battery power and keeping the unit away from hot or humid environments helps preserve long-term stability.

Same physical fit as the original

The black replacement matches the original battery dimensions, so installation requires no chassis modification or adapter brackets. Connector placement aligns with the factory layout for a direct plug-in fit. For storage periods longer than a month the supplier recommends keeping the charge above 80 percent and recharging at least once monthly; disassembly, puncture or exposure to fire and water must be avoided.

Questions about this item

How do I install the L18D3PG1 battery in my Lenovo 300E Chromebook 2nd Gen, and which step is often missed?

Power off the laptop, remove the bottom screws, disconnect the old pack connector, fit the new 11.25V unit, reconnect the cable, replace the cover and screws, then fully charge and discharge the pack two or three times to calibrate the fuel gauge.

What maintenance will this 42WH Li-ion pack need later?

If the laptop is stored without the battery, charge it above 80 percent at least once a month; avoid leaving the AC adapter connected continuously while using the battery and keep the pack out of hot or humid environments.

What limit appears first during sustained heavy use of this 3735mAh battery?

The pack will reach its thermal threshold before the cells hit voltage cut-off, so prolonged high-current draw reduces run-time per charge until the temperature drops.
