Lithium Ion Battery
4.1 Characteristics
34
1: This is an earth-friendly battery, offering a very high energy density, that does not contain
lead, mercury, or cadmium.
2: It has a Battery Management Control (BMC) system that uses a computer to keep track of the
charge/discharge status, operating conditions, and temperature of the battery.
3: It is not susceptible to the memory effect even if it is subjected to shallow charge and
discharge cycles. It is unnecessary to refresh charge this battery, whose charge can be
replenished.
4: It has LED lamps to indicate the battery’s residual capacity. This battery has a large capacity,
and deteriorates only moderately. It uses a relative capacity indication system that lights all
the lamps each time a charge is completed.
5: Recommended ambient temperatures
Recommended operating temperature range: 0°C to 35°C ambient temperature
Recommended storage temperature range: 10°C to 25°C room temperature
Recommended charging temperature range: 10°C to 25°C room temperature
6: The capacity of the battery will deteriorate naturally regardless of whether it remains unused
or is stored properly. Even if it is used correctly, its performance will deteriorate and its
absolute capacity will decrease gradually with the extent of use and the passage of time.
Characteristics due to the use environment
• Compared to traveling on a level surface, frequent travel uphill and over curbs will consume more power and
reduce the travel range.
• Due to the characteristics of the battery, the travel range may be reduced due to changes in ambient
temperature, which affect the temperature of the battery.
Battery’s deterioration characteristics
• Although the extent of reduced capacity varies by operating conditions, it will decrease to approximately 60%
of the capacity of a new battery after 700 charge/discharge cycles.
• Storing the battery at temperatures other than recommended will accelerate deterioration, particularly when a
fully charged battery is stored at high temperatures. Example: Avoid storing a battery inside an automobile or
luggage compartment in the summer.
Recycling the battery
This is a recyclable battery that contains valuable resources. Contact the JW dealer to recycle your used
batteries.
Proper use of the battery
NOTE
• Charge the battery in a cool area that is not exposed to direct sunlight.
• About once or twice each month, leave the battery connected to the charger for 8 to 12 hours after it is charged. The charger will replenish the
charge automatically. (The charger will automatically turn off its internal power approximately 12 hours after the charge lamp goes out.)
• Store batteries in a cool, dry area. Before storing a battery for a long period of time, charge it until 2 to 4 of its lamps are lighted. Do no store
it with only 1 lamp lighted or fully charged.
