The resistors R
and R
determine the final charging volt-

age and R
the initial charging current. D
prevents dis-

charge of the battery throught the regulator.
The resistor RL limits the reverse currents through ther
regulator (which should be 100 mA max) when the bat-
tery is accidentally reverse connected. If R
is in series
L
with a bulb of 12 V/50 mA rating this will indicate incor-
rect connection.
