.
let the battery at rest for about 2 hours to allow the
cooling of the plates. '
A certain part of the electrolyte will be absorbed by the
separators and by the plates, so that it will be necessary
to add more electrolyte to establish the right leveL.
To check the electrolyte level use only glass sticks or
ebonite.
.
First charge
Take down the breathers and connect the battery with
a source
of direct current, having an intensity equal to
1/10 of the normal 10 hours capacity, for a maximum
period of at least 10 consecutive hours.
Take care that during the charge the temperature of the
electrolyte does not overpass 500 C (1220 F).
The charge has to be interrupte,d:
a) when the above mentioned effective number of hours
is elapsed, reckoning of course also the eventual in-
terruptions ;
b) in case of an intense ebullition in all the elements;
c) in case if for at least 3 consecutive readings at inter-
vals of one hours each, the density of the electrolyte,
and the voltage of each element remain the same.
At the end of the charge, the electrolyte should have re-
covered the initial density, and the voltage of each
element should arrive at a minimum of 2.7 Volts under
charge, that is 8.1 Volts for a battery of 3 elements and
of 16.2 Volts for a battery of 6 elements.
At this point the battery is ready to be put in service.
SUCCESSIVE CHARGES
The successive charges have to be made preferably with a
current having an intensity in Amp. equal but not greater
than 1/10 of the normal
10 hours capacity.
If during the charge the temperature, checked with a sui-
table thermometer immerged into the electrolyte should
reach 500 C, (1220 F), it will be necessary to reduce or to
interrupt the charge until the temperature falls at least
below 400 C (1040 F).
