expressly approved by the manufacturer could void the user’s authority to operate the equipment.
• If the recharging operation doesn’t complete within the specified recharging time, stop further
charging immediately. Otherwise, acid leakage, overheating, smoke emission, bursting and/or
ignition can occur.
• Do not put the battery pack into a microwave oven or pressurized container. Rapid heating or a
disrupted seal can lead to acid leakage, overheating, smoke, bursting and/or combustion.
• If the battery pack leaks or emits a bad odor, remove it from any exposed flame. Otherwise, the
leaking electrolyte may catch fire and the battery pack may smoke, burst or combust.
• If the battery pack emits a bad odor, generates heat, becomes discolored or deformed, or in any
way appears abnormal during use, recharging or in storage, stop using it. A faulty battery pack can
leak acid, overheat, smoke, cause odor, burst, and/or combust.

Cautions:
• Do not subject the battery pack to intense sunlight or high temperatures, such as in a car in hot
weather. Otherwise, acid leakage, overheating and/or smoke emission can occur, performance
may be diminished and its service life may be shortened.
• The battery pack incorporates built-in safety devices. Do not use it in a location where high levels
of static electricity may be present. Otherwise, the safety devices can be damaged, possibly
leading to acid leakage, overheating, smoke emission, bursting, and/or combustion.
• Recharge the battery at a temperature in the range of 32 °F to 113 °F (0 °C to 45 °C). Recharging at
temperatures outside this range can cause acid leakage and overheating, and may damage it.
• If any fluid leaking from the battery pack contacts your skin or clothing, wash it off immediately
with running water. Otherwise, injury can occur.
• Store the battery pack in a location where children cannot reach it. Make sure that children cannot
remove the battery pack from the battery charger or equipment.
• If you find rust, a bad odor, overheating and/or other irregularities when using the battery pack,
return it your supplier or vendor.
• To reduce the risk of fire or burns:
1. Do not open, disassemble, or service the battery pack.
2. Do not crush, puncture, short external contacts, or dispose of in fire or water.
3. Replace only with a battery pack designated for this product.
