6-2. Extra Precautions in Sales Promotion
The following points must be given during sales promotion.
6-2-1. Charging may not be possible when the battery temperature is high
Charging may not be possible if the temperature of the battery is high after it has been exposed to direct sunlight for
a long time or immediately after it has been used.
The customer should be advised in such a case to place the battery in a shaded area with good airflow, and allow
sufficient cooling before recharging. This phenomenon is common to all existing batteries and chargers which
employ temperature sensitive overcharge protection devices. The cooling time required before recharging varies
from a few minutes to about 30 minutes, depending on the load, duration of use and ambient temperature.
6-2-2. Inserting a battery into a charger in reverse direction can cause serious damage to the battery and the
charger
Inadvertently inserting a battery into the charger in the reverse direction will not only make it impossible to charge
the battery but also decrease the service life of the battery and cause damage to the charger. Customers should
be advised to correctly insert the battery into the charger.
