9-2 DC OUTPUT

When the generator is employed to recharge batteries. care must be exercised about the specific gravity of electrolk-te rn each batter\. case.

9-2-l MEASURING THE SPECIFIC GRAVITY OF ELECTROLYTE:

The specific gravity changes with temperature; therefore. it is converted to another corresponding to 20°C.

S20	=	St + 0.0007 (t - 10)
where
S~J	=	Specific gravity corresponding to 20°C
SI	=	Measured value
t	=	Temperature at time of measurement

9-2-3 BATTERY CAPACITY:

The battery capacity is expressed in units of ampere-hour (AH). One AH stands for the capacity capable of providing one

ampere of current for one hour.
