DANGER
Do not charge the battery near fire or under direct sunlight!
●
If the battery's protection circuit is damaged, the battery may
charge at extreme current (or voltage) and an abnormal chemical
reaction may occur. The battery may generate heat or smoke,
rupture, or burst into flame.
Use only the specified charger and observe charging
●
requirements!
If the battery is charged in unspecified conditions (under high
temperature over the regulated value, excessive high voltage or
current over regulated value, or with a remodeled charger), it may
overcharge or an abnormal chemical reaction may occur. The
battery may generate heat or smoke, rupture, or burst into flame.
Do not pierce the battery with any object, strike it with an
●
instrument, or step on it!
This may break or deform the battery, causing a short-circuit. The
battery may generate heat or smoke, rupture, or burst into flame.
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 circuit is
damaged, the battery may charge at an abnormal current (or
voltage), and an abnormal chemical reaction may occur. The
battery may generate heat or smoke, rupture, or burst into flame.
Do not use the battery pack if it is damaged in any way!
●
The battery may generate heat or smoke, rupture, or burst into
flame.
Do not solder directly onto the battery!
●
If the insulator is melted or the gas release vent or safety function
is damaged, the battery may generate heat or smoke, rupture, or
burst into flame.
Do not reverse the battery polarity (and terminals)!
●
When charging a reversed battery, an abnormal chemical reaction
may occur. In some cases, an unexpected large amount of current
may flow upon discharging. The battery may generate heat or
smoke, rupture, or burst into flame.
