21 BATTERY

21.1 BATTERY
The battery's voltage is 12 V with a capacity of 13 Ah; it is charged by the generator.
The battery used on the motorbike is a sealed type battery (without maintenance) which does not require any checks.
Charging instructions
NOTE It contains toxic substances (Pb and H2 SO4); extremely high currents, avoid short circuits; do not recharge in the
sealed container; using different battery chargers will cause irreparable damage to the battery.
General notes
Charging pure-tin sealed accumulators, just as other re-chargable accumulators, is a matter of saving the energy
supplied during discharge. As this process is in some ways inefficient, it is necessary to bring back to the accumulator
from 105% to 110% of the amperes-hour supplied during discharge. The quality of the power necessary to completely
recharge the battery depends on the flatness of the accumulator, on the method, recharging time and temperature.
It is important that the battery is capable of supplying all or nearly all of its capacity before receiving the required over-
charging. However, to obtain an optimal duration in terms of cycle numbers, the battery must periodically receive the
required over-charging.
Charging can be carried out in different ways.
The aim is to convey current through the battery in the direction opposite to the discharge. Constant voltage charging is
the standard method used to charge lead acid typeaccumulators.
Constant voltage charging:
The voltage charging method is the most efficient for charging sealed lead- acid pure-tin accumulators.
Using
this charging method, it is not necessary to limit the maximum current supplied by the charger. The voltage must
however be adjusted so that it is within the values prescribed below. This feature is due to the internal resistance of the
battery. It is extremely low and features a high recombination efficiency during charging. We recommend to observe the
following values for constant voltage charging:
Cyclic use:
•
from 14.7V to 15.0V for battery at 25°C. No current limit requested.
Buffer use:
• from 13.50V to 13.80V for battery at 25°C. No current limit requested.
Removal:
•
Remove the fairings;
•
Release the locking belt;
•
Disconnect the negative terminal, then the positive one by unscrewing the nuts;
•
Remove the battery from the motorbike.
NOTE Always disconnect the negative terminal first then the positive one.
NOTE The negative terminal is black, while the positive one is red.
Refitting:
•
Apply protective spray for electrical contacts on the battery terminals;
•
Insert the battery in its seat on the motorbike;
• Connect the positive terminal then the negative one;
• Hook the locking belt once again.
•
Refit the fairings.
