RATING BY:
If the tester indicates poor battery condition, allow the battery to stabilize for a few minutes
and check the open circuit voltage by voltmeter. This is a good measure of the percent
charge in the battery. The battery is considered charged if it measures 75% or more. If it
failed the load test with 75% charge, it should be replaced. If the battery charge measures
less than 75%, it should be charged and load tested again. Replace the battery if it fails
again. The values in the following charge are for a 12 volt battery:
OPEN CIRCUIT VOLTS*
11.7 Volts or lower
12.0
12.2
12.4
12.6 or higher
BATTERY CONDITION
Battery capacity is good. May or may not be fully charged.
Determine state of charge by checking specific gravity (use
hydrometer). If gravity is less than full charge, check for pos-
sible charging system trouble or electrical drain. Recharge
battery to full charge.
Battery capacity is unsatisfactory. Battery may be either: (1)
defective or (2) partly discharged. To determine which, check
specific gravity. If gravity is over 1.225, battery is considered
defective. If gravity is under 1.225, recharge battery and re-
test. If cell-to-cell gravity varies more than 0.025 (25 points),
cell trouble may exist. If charging does not bring gravity to full
charge level, the battery is either sulfated or has lost active
material.
Battery may be defective (e.g. a bad cell). For a quick check,
release load switch and note volt meter reaction. If voltage re-
covers to 12.0 volts or more in a few seconds battery is prob-
ably defective. If voltage recovers slowly, battery may have
run down. For more accurate results, check gravity and follow
above procedure.
