[ESSENTIAL CARE TIPS - PLEASE READ] (1) Fully charge before first use. (2) Recharge every 2-3 months during storage - lithium batteries self-discharge 3-5% monthly and deep discharge causes permanent damage. (3) Jump start when battery shows 75%+. (4) Allow 5-min cooldown after 10 min of continuous inflation
