Lenovo 45Wh Battery Frequently Asked Questions (FAQs)
Will this fit the newer 100e, 300e, or 500e Chromebooks?
No. While they are part of the same education family, the newer models use physically different battery designs. This L15M3PB1 battery is strictly for the N22 and N42 models.
How do I extend the life of my new battery?
Avoid letting the battery drain to 0% frequently. If you use the laptop while plugged in most of the time, try to use the "Conservation Mode" in Lenovo Vantage (if available) to limit the charge to 60%, which significantly reduces cell degradation.
