5.6.1. Preparing the battery for operation

Electrolyte filling of accumulator
Adhesive tape placed over the deaeration hole and filler caps is removed and filler caps are
uncapped. It´s necessary to fill each cell with electrolyte up to the level of upper mark on
(cover)case. Electrolyte is formed by diluted sulphuric acid according to ČSN 65 1230norm,
with density of 1,28 g/cm3 and temperature of 25 C. After filling it´s necessary to let
accumulators plates saturate properly with electrolyte of prescribed density during 20 minutes
without further charging. To check-up and eventually top up the level of electrolyte, to cap
the filler caps, wash off the accumulator, dry up, put on the deaeration tube on outlet of
deaeration and fix the accumulator into motorcycle. The motorcycle has to be immediately
put into operation and go through riding of approx.100 kms.
Charging
The accumulator which is activated after 6 months period from the date of production and
accumulator which is not immediately in operation after being filled with electrolyte, has to
be charged. Likewise accumulator with voltage lower than 12 V and electrolyte with density
lower than 1,26 g/cm3 has to be charged. The accumulator is charged by current of 0,25 - 0,5
A (battery charger) with possibility of air regulation as long as the voltage and density of
electrolyte are not changing any longer.
Note
Charging period depends on state and capacity of accumulator. During the charging it´s
necessary to follow temperature of accumulator which should not exceed 40 C. After
exceeding the mentioned temperature the accumulator has to be cooled (e.g. by running
water).
When higher density of electrolyte we keep filling up the level by distilled water , only.- The
voltage of fully charged accumulator is 12,6 V, i.e. 2,1 V per cell. From the structural reason
the voltage of individual cells of this type cannot be measured.
When operating the motorcycle the terminal connectors have to be permanently connected
with battery when engine is running. It´s not even permissible "trial" disconnecting of
accumulator when engine is running ! We draw also attention to the following situation :
during arc welding the terminal connectors of regulator have always to be disconnected
together with terminal connectors of rectifier (eventually even earth connection eye on
regulator casing).
