TIP
If you forget the date you started to use the lithium ion battery.
• 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 ap-
proximately 700 charge cycles, when fully charged from 0 residual
capacity).
The battery
’
s manufactured date is printed on its bottom. Use it as a reference.
