(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.
• Battery life alert
The capacity indicator lamps start alerting
you from 3 months prior to the battery be-
coming no longer chargeable 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.
• 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 battery cannot be charged.
If you forget the date you started to use the lithium ion battery.
TIP
The battery's manufactured date is printed on its bottom. Use it as a reference.
• The start date of battery usage is defined as the date the user charged the bat-
tery for the first time after shipment from the factory.
(This does not match the manufactured date above.)
• Once the integral charge capacity reaches 8,000 Ah, the battery will not be us-
able even if it has not been 8 years.
* The integral charge capacity of 8,000 Ah is approximately 700 times the capacity
of the "ESB1" lithium ion battery (hence equivalent to approximately 700 charge
cycles, when fully charged from 0 residual capacity).
The capacity lamps
turn on and off repeat-
edly for 5 seconds,
in the order of the
arrows.
