Lithium Ion Battery and Charger
8.1. Features of the Lithium Ion Battery (ESB1)
• Has a higher energy capacity compared to the nickel metal hydride battery.
• Equipped with Battery Management Control System (BMC).
(built-in microprocessor)
This is a system that uses a computer to track charge/discharge status, operating conditions, and
temperature.
• Even with repeated shallow discharge/charge cycles, it is difficult for the memory effect to occur.
Therefore, refresh charging is not necessary, and its charges can be replenished additively.
• An environmentally-friendly battery that does not contain mercury or cadmium.
• Compact but high capacity. (25 V × 11.8 Ah)
8.2. How to Use the Lithium Ion Battery (ESB1)
(1)
Attaching and removing the battery to and from the wheelchair
For instructions on attaching and removing the lithium ion battery to and from the wheelchair, see
“3. Before Sitting in the Wheelchair” and “5. After You are Finished Riding the Wheelchair”.
(2)
Checking the residual capacity of the battery
Press the indicator switch to display the battery’s residual capacity.
(3)
Storing the battery
Store batteries in a cool, dry area. If you are not planning
on using the battery for a long period of time, charge it so
that the 3 of the capacity indicator lamps light up, and then
store it.
To store the battery without using it for over 3 months,
check every 3 months to see if all 3 capacity indicator
lamps light up. If 2 or less lamps turn on, charge the
battery until 3 lamps turn on.
Always put on the protective cap when storing the battery.
