› Check there is sucient charge in the battery for
the journey you intend to make before setting o.
› In winter the distance you can normally cover with
the battery operating normally is less. Only move
the battery om the warm room where you store
it and t it on your Pedelec just before you set o.
This prevents low temperatures om reducing the
distance you can normally travel. A corresponding
diagram is provided in
Chapter 12 “Technical data”.
› The distance you cover can vary depending on the
topography, your handling, the condition of the
battery and the assist level you are using.
› If all diodes ash consecutively, or several ash
at the same time (2 – 3 diodes), the battery is
damaged.
Before taking the battery to your specialist cycle shop
to have it checked, put the battery in the charger for
one minute then test it again.
6.5 Service life and warranty
6.5.1 the electric drive
The Panasonic ont electric drive is a lly-developed
durable and maintenance-ee electric drive. It is a wear
part for which a two-year warranty applies.
6.5.2 the battery
Batteries are wear parts. Wear parts also come with a two-
year warranty.
If the battery develops a fault during this period, your
specialist cycle shop will of course replace it. A fault does
not constitute normal ageing and battery wear.
The service life of the battery depends on dierent factors.
The most important wear-relevant factors are
• the number of charge cycles and
• the age of the battery.
When you have lly charged and discharged your battery
1,100 times, it will still have 60% of its initial capacity,
providing it has been well looked aer:
BATTERY
REMAINING
CAPACITY
~ DISTANCE COVERED
8 Ah 4.8 Ah 19,360km
12 Ah 7.2 Ah 30,800km
18 Ah 10.8 Ah 52,800km
From a technical standpoint therefore, the battery is
"used" at this point. It also goes without saying that the
battery ages. Even if you do not use your battery, its ca-
pacity reduces.
Providing you can still cover the journey distances with
this remaining battery capacity, you can of course con-
tinue using it. If the capacity is no longer sucient, you
can take your battery to a specialist cycle shop who will
dispose of your battery and supply you with a new one.
› You can extend the service life of the battery by
lly recharging it aer every journey, even if it is
small. The Panasonic li-ion cobalt battery has no
memory eect.
› You can also extend the service life of the battery
by using the assistance selectively. Avoid, for ex-
ample, using gears that make pedalling dicult
with the most powerl assist level.
