Meter Display
Battery capacity is good. May or may not be fully
charged. Check the charge state by testing the Specific
Gravity (SG) with a Hydrometer (not included).
If SG is less than full charge, check for possible
charging system trouble. Recharge to full level.
If the Display Meter needle is steady, the battery capacity is not
good. Battery may be defective or partly discharged. Check SG.
If over 1.225, the battery is defective.
If below 1.225, recharge battery and retest.
If there is a difference in SG between cells over 2 points
(0.025), a particular cell may be damaged.
If charging does not bring SG to full charge level, then
battery is either sulfated or has lost its active material.
If the Display Meter needle is falling, the battery is
defective or has a bad cell. For a quick check, release
the Switch and note Display Meter reaction.
If voltage recovers to its full potential after only a few
seconds, the battery is probably defective.
If the voltage recovers slowly, the battery may only
be run down. Check SG, recharge and retest.
If the Display Meter needle reads OK, charging system is functional.
If it falls on the low red or high red areas, charging
system may be malfunctioning.
