several times, this indicates that the battery is worn out and the

specified regulations rather than throw them into residential garbage.

fire or explosion.
Do not press with great force when installing the battery because this
may result in leakage, overheating, explosion or fire.

If the battery becomes hot, changes in color or gets deformed during
the course of use, charging or storage, please immediately stop using
and replace it.
Keep the battery away from dampness to prevent overheating,
smoldering or erosion.
Do not leave the battery in direct sunshine, around a car or
