● Be sure to store the disconnected battery with the protective cap on it.
Exposed contacts can cause short circuits and lead to a fire or battery rupture.

TIP
Refer to "14. Troubleshooting, Repairs, Warranty".
• If the vehicle has traveled a long distance or on a long uphill grade, or if it has been left out-
side in the cold for a long time, the battery temperature may not be suitable for charging.
In such a case, the charger may not start charging (remains in standby mode) until the bat-
tery has reached a suitable temperature.
(3) Suitable temperature for charging
Charge the battery in an environment with a tem-
perature of 50 to 77°F (10 to 25°C).
• To protect the battery, if the internal temperature
of the battery is under 32°F (0°C) or over 104°F
(40°C), charging does not start. Instead, it enters
a standby mode. During this time, the charge
lamp (green) flashes.
While in standby mode, when the battery reach-
es an appropriate temperature, the charge lamp
will change from a flashing to an "on" state, and
charging will start automatically. (The length of the
standby time varies with conditions.)
• The battery temperature increases during charging. However, if the battery temperature rises
above 122°F (50°C), the power for the charger will turn off to protect the battery.
Since charging has not ended, it is necessary to charge again after the battery temperature has
decreased.
Charging a battery immediately after travel, or charging a new battery is likely to cause its tempera-
ture to increase, which increases the likelihood of the charger stopping charging before completion.
