The battery systems of e-learning devices primarily use lithium polymer batteries, achieving rechargeable and lightweight designs. AI learning machines are equipped with large 8000-10000mAh batteries to support extended video learning sessions, while e-ink learning notebooks achieve ultra-long battery life with 3000-4000mAh batteries. Portable devices such as dictionary pens use 600-2200mAh lithium batteries or two AA batteries (180 hours of battery life), balancing portability and practicality.
