Product Usage Instructions
New Makita compatible lithium batteries are pre-charged with residual power before delivery. To fully activate Grade A+ cell activity, optimize discharge performance and extend cycle life, please fully charge the battery before formal use. For long-term storage, complete a full charge and discharge cycle every two months to prevent cell dormancy, capacity attenuation and internal resistance increase. Store in dry, cool and ventilated places, away from high temperature, humidity and flammable areas. Only use the dedicated original 21V charger; mismatched chargers are strictly prohibited to avoid unstable current, abnormal voltage, short circuit and cell damage. Charge in open, dry and ventilated environments without flammable materials. Cut off power timely after full charging to prevent overcharging. Never short-circuit positive and negative poles with metal objects, and avoid water immersion, violent dropping, extrusion, puncture and burning. Non-professionals are not allowed to disassemble, modify, weld or repair the battery. Stop using immediately in case of abnormal heat, bulging, power failure and excessive power attenuation, cool down in ventilated place and contact after-sales support instead of self-repairing. Waste batteries shall be recycled in accordance with international environmental protection standards to avoid pollution and safety hazards.
