(2) Battery’s deterioration characteristics
All batteries are consumables. A battery gradually deteriorates and its capacity decreases over time
and with use.
The extent to which the capacity decreases by deterioration depends on the use conditions.
(3) The life of the lithium ion battery
The life of the lithium ion battery (ESB1) is 8 years from its initial charging, or 8,000 Ah of integral
charge capacity.
For a lithium ion battery, its capacity will decrease to approximately 60% of that of a new bat -
tery after 700 charge cycles, under normal use.
TIP
Even if a battery is not used, when it is stored over a long period of time, it will deteriorate and its ca-
pacity will decrease.
When you are using multiple batteries, alternate between the batteries.
Immediately after the lithium ion battery has successfully completed charging (fully charged),
pushing the indicator switch will always show all 5 lamps lit. Even if deterioration has pro -
gressed, all 5 lamps should turn on when fully charged. This display format was adopted for
this battery, as the rate of deterioration of lithium ion batteries is gradual.
TIP
• Battery life alert
The capacity indicator lamps start alerting you from 3
months prior to the battery becoming no longer charge-
able due to its end-of-life, or when the integral charge
capacity reaches 7,800 Ah.
When charging has completed and the charger plug is
unplugged, the capacity indicator lamps turn on and off
as shown in the figure on the right.
The capacity lamps
turn on and off re -
peatedly for 5 sec -
onds, in the order of
the arrows.
• When the battery reaches end of life
Once the battery reaches its end of life, the lamp on the charger will not turn on when attempting to
charge the battery. Moreover, the battery’s capacity indicator lamps no longer turn on and the bat-
tery cannot be charged.
