If you forget the date you started to use the lithium ion battery.
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 battery 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 usable even
if it has not been 8 years.
* 8,000 Ah the integral charge capacity 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).
