Do not rub your eyes if the battery liquid leaks and comes into contact with your eyes. Rinse well with clean
water such as tap water, and seek medical attention immediately.
If charging is not completed after the specified time elapses, remove the battery from the product or charger
and stop charging.
If you notice any unusual odor, heat, discoloration, deformation, fluid leakage or any other characteristic
apart from what you are used to while using, charging or storing the battery, then perform the following
immediately.
• Unplug the power cord from the AC outlet.
• Power off the product.
• Remove the battery from the product or charger. Keep the battery away from fire and avoid using it.
Otherwise, there may result in fire, burn, injury, or electric shock.
Charge the battery in the recommended temperature range from 5°C to 35°C (41 to 95 °F).
Store the battery in a location out of reach of young children. Ensure that the battery is not placed in the
mouth or swallowed accidentally.
Occasionally clean the terminal by wiping with a dry cotton swab or the like.
When storing the battery, avoid storing in the following state.
• In a fully charged state (a state immediately following the completion of charging)
• In a state with no remaining capacity (the battery is so exhausted that it is even impossible to turn on the
product)
Doing so may result in a degraded battery performance or reduced lifetime. An optimal remaining
capacity to store the battery is approximately 40%.
Even when the battery is expected not to be used for a long time, do the following about every six months
to enable the battery to maintain its performance: fully charge the battery and use it to drive your product
until its remaining capacity decreases to approximately 40%, then remove the battery from the product and
store it in a cool room with low humidity.
