  • Long-Term Storage: If storing the battery for an extended period (e.g., several months), charge it to approximately 50-60% capacity and store it in a cool, dry place. Recharge it every 3-6 months to prevent deep discharge. The battery is designed for low self-discharge, retaining approximately 80% capacity after one year of non-use.
