Battery depletion
The electric output capacity of the
Li-ion battery used in the EC-03 gradu-
ally decreases in the course of use. Al-
though the extent of depletion varies
based on the conditions of use, electric
output capacity typically decreases to
70% of a new battery when having trav-
eled 8000–10000 km for two years.
This is equivalent to charging about
500 times with the condition of riding
16–20 km on a single charge.
Battery electric output auto-stop-
ping function
The battery is equipped with a function
to prevent further use in case of exces-
sive depletion. When eight years have
passed since initial battery charging or
the accumulated charging amount has
reached 14000 Ah, the battery will no
longer be usable.
TIP
 When the battery is replaced with
a new one, fully charge the battery
once before using it. If the battery
is not fully charged, the battery lev-
el indicator does not show the pre-
cise battery level.
 At low temperatures such as 0 C,
the electric output capacity de-
creases by approximately 20%
compared with normal tempera-
ture.
 If a depleted battery is used at low
temperatures, the electric output
capacity decreases by approxi-
mately 20% compared with normal
temperatures.
