NOTE:
When standby for cooling battery, UC18YML2 cools the overheated battery by cooling fan.
(However, the cooling fan does not function when charging the battery with a DC 12V in-car power source.)
(2) Regarding the temperatures of the rechargeable battery
The temperatures for rechargeable batteries are as
shown in Table 2, and batteries that have become hot
should be cooled for a while before being recharged.

Temperatures at
which the battery
can be recharged
BSL1830C, BSL1850 0°C – 50°C
(3) Regarding recharging time
Depending on the combination of the charger and
batteries, the charging time will become as shown in
Table 3.
