7DANGER• Use only the specified charger and observe chargingrequirements!If the battery is charged in unspecifi ed conditions (under hightemperature over the regulated value, excessive high voltage orcurrent over regulated value, or with a remodeled charger), it mayovercharge or an abnormal chemical reaction may occur. The batterymay generate heat or smoke, rupture, or burst into fl ame.• Do not pierce the battery with any object, strike it with aninstrument, or step on it!This may break or deform the battery, causing a short-circuit. Thebattery may generate heat or smoke, rupture, or burst into fl ame.• Do not jar or throw the battery!An impact may cause the battery to leak, generate heat or smoke,rupture, and/or burst into flame. If the battery’s protection circuitis damaged, the battery may charge at an abnormal current (orvoltage), and an abnormal chemical reaction may occur. The batterymay generate heat or smoke, rupture, or burst into fl ame.• Do not use the battery pack if it is damaged in any way!The battery may generate heat or smoke, rupture, or burst intofl ame.• Do not solder directly onto the battery!If the insulator is melted or the gas release vent or safety function isdamaged, the battery may generate heat or smoke, rupture, or burstinto fl ame.• Do not reverse the battery polarity (and terminals)!When charging a reversed battery, an abnormal chemical reactionmay occur. In some cases, an unexpected large amount of currentmay fl ow upon discharging. The battery may generate heat orsmoke, rupture, or burst into fl ame.• Do not reverse-charge or reverse-connect the battery!The battery pack has positive and negative poles. If the battery packdoes not smoothly connect with a charger or operating equipment,do not force it; check the polarity of the battery. If the battery pack isreverse-connected to the charger, it will be reverse-charged and anabnormal chemical reaction may occur. The battery may generateheat or smoke, rupture, or burst into fl ame.
