3.1. Lithium-ion battery
■ To make the battery last longer
• If the vacuum cleaner is not being used for more than a month, fully charge the battery before storing the vacuum cleaner and
recharge the battery once a year. (If the vacuum cleaner is stored with an uncharged battery, it may cause the battery to become
defective or reduce the battery life.)
• When the battery runs out and the vacuum cleaner shuts down during cleaning, pressing the “AUTO/HIGH” switch again may
allow the vacuum cleaner to keep working for a little while, but do not repeat this action, as it can shorten the battery life.
• Charge the battery in a location with a room temperature of between 5 and 35°C. The battery will not recharge properly in a loca-
tion with low room temperature or a location with high room temperature, such as a location exposed to direct sunlight. The oper-
ating time may become shortened or the battery may take longer to recharge.
■ Battery status indicator
• The battery status indicator makes the battery status indicator lamp either light up or blink according to the battery voltage during
operation.
• If the vacuum cleaner is shut down by pressing the “OFF” switch while the battery status indicator lamp is lit up or blinking, the
lamp will remain lit up or blinking for 8 seconds before going out.
• If the vacuum cleaner is switched on again after being shut down, the battery status is indicated as it was during prior operation.
• When the battery status reaches zero during operation and the vacuum cleaner shuts down, the battery status indicator lamp
remains blinking for 8 seconds and then goes out.
• If the “AUTO/HIGH” switch is pressed when the battery status is at zero, although the motor will not run, the battery status indica-
tor lamp will blink for 8 seconds and then go out.
■ Battery built-in thermistor (temperature abnormality)
• If the battery temperature is above 77°C, according to the built-in thermistor, or if the thermistor burns out (open state), the motor
will be shut off and the “CHECK” lamp will be lit up.
• After the motor is shut off, the “CHECK” lamp will remain lit up for 5 minutes before going out. The device will then go into
standby mode.
• *The “AUTO/HIGH” switch will not work when the “CHECK” lamp is lit up.
■ Recharging
<Commencement of recharging>
• If the battery temperature is not between 0 and 45°C it will
not commence recharging, but will go into temperature
standby state.
• If the temperature standby state continues for 180 minutes,
the temperature for recovery from the temperature standby
state will change to between 0 and 50°C.
• If the temperature standby state continues for 300 minutes,
there is a charging abnormality.
(The battery status indicator lamp will blink rapidly [0.15sec-
ON/0.15sec-OFF].)
<During recharging>
• If the battery temperature is below -1°C or above 60°C, the
battery will stop recharging and will go into temperature
standby state.
• If the temperature shifts to between 0 and 57°C during tem-
perature standby, recharging will recommence.
• If the temperature standby state continues for 120 minutes,
there is a charging abnormality.
(The battery status indicator lamp will blink rapidly [0.15sec-
ON/0.15sec-OFF].)
<Completion of recharging>
• Charging time: About 3 hours (time required to recharge an
empty battery at an ambient temperature of 20°C when the
battery is still new)
*If the charging temperature standby state is included,
recharging may take up to 8 hours.
• If charging current is below 0.1A and battery voltage is
between 23.4V and 26.4V, recharging is complete.
• If after 270 minutes of charging time the battery voltage is
between 23.4V and 26.4V, recharging is complete.
• Anything other than the above conditions should be consid-
ered a charging abnormality.
(The battery status indicator lamp will blink rapidly [0.15sec-
ON/0.15sec-OFF].)
