Nickel Metal Hydride Battery
3.1 Characteristics
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
charge/discharge status, operating conditions, and temperature.
3. Although it is susceptible to the memory effect that reduces its discharge capacity when it
is subjected to shallow charge and discharge cycles, it can be solved by refresh charging it
periodically.
4. It has LED lamps to indicate the battery’s residual capacity. It uses an absolute capacity indi-
cation system that indicates capacity in accordance with the extent of the battery’s deterio-
ration.
5. Recommended ambient temperatures
Recommended operating temperature range: 0°C to 35°C ambient temperature
Recommended storage temperature range: 10°C to 25°C ambient temperature
Recommended charging temperature range: 10°C to 25°C ambient temperature
6. The capacity of the battery will deteriorate naturally regardless of whether it remains unused
or stored properly. Even if it is used correctly, its performance will deteriorate and its abso-
lute 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 300 charge/discharge cycles.
• Storing the battery at temperatures other than the recommended range will accelerate deterioration, particularly
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
e-drive
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. If the temperature of the battery is too high, charging might not start
or might not finish.
• Even if it is subjected to shallow charge and discharge cycles, the memory effect can be solved by refresh charging the battery periodically.
• Deep discharges that use up the battery’s capacity will overload the battery and shorten its use life.
• If you use more than one battery, use them alternately because their performance will deteriorate over time even if they remain unused.
• Store batteries in a cool, dry area. Fully charge a battery that you do not plan to use for a long period of time.
