vii
Do not charge the battery near fires 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 remodelled 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.
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.
