Based On Sg Reading Recharging Operation - Suzuki RG250 Service Manual

6·19 ELECTRICAL SYSTEM
Check the electrolyte level and add distilled water,
as necessary, to raise the electrolyte to each cell's
MAX. level.
Check the battery for proper charge by taking an
electrolyte S.G. reading. If the reading is 1.22 or
less, as corrected to 20°C, it means that the battery
is still in a discharged condition and needs re-
charging.
BASED ON S.G. READIN G
RECHARGING OPERATION
To correct an S.G. reading 20° C, use the table at
the right.
To read the S.G. on the hydrometer, bring the
electrolyte in the hydrometer
CD
to eye level and
read the graduations on the float sca le bordering
on the meniscus (curved-up portion of electrolyte
surface), as shown in figure .
Check the reading (as corrected to 20°C) with
chart to determine the recharging time in hours by
constant·current charging at a charging rate of 0 .5
amperes (which is a tenth of the capacity of the
present battery).
Be careful not to permit the electrolyte tempera·
ture to exceed 45°C, at any time, during the
recharging operation. I nterrupt the operation, as
necessa ry, to let the electrolyte cool down.
Recharge the battery to the specification.

CAUTION:
Constant·voltage charging, otherwise called
"quick" charging, is not recommended as it
cou ld shorten the life of the battery.
