How to Charge Lithium Batteries: Short & Practical Guide

A new practical guide on lithium battery charging has been released, addressing the most common user questions: when to charge, whether to leave chargers plugged in, how to store batteries in winter, and what to do during long periods of inactivity. The guide emphasizes a key rule – never let LiFePO₄ batteries sit at 0% for extended periods, as deep discharge damages them more than frequent charging. Recommended practices include charging at 20%–30%, stopping at 80%–90% for daily use, and storing at 50%–60% charge. Following these simple steps can significantly extend battery lifespan and ensure safety.
