TESTING
After performing the visual inspection, test the battery for potential internal electrical damage.
1.
Using a battery post cleaner or wire brush, clean any corrosion buildup from the terminals.
2.
Using voltage meter, test Open Circuit Voltage (OCV) of the battery. Set meter to lowest VDC reading that is
greater than 15 VDC. Place the positive lead (red) on the battery post marked with a (+) sign and the negative
lead (black) on the other battery post with the (-) sign. Note the voltmeter reading and, with chalk or pencil,
record test OCV on top of battery. This OCV becomes a reference point for future tests and should be removed
at the conclusion of charging and testing.
3.
Determine if internal damage exists. Many testers will not give a reading if OCV is less than seven (< 7) VDC.
If no reading is given, proceed with charging procedures (WP 0006). If no reading is given, charge the battery
for 24 hours and retest with Multimeter and Analyzer. If no change is detected after 24 hours of charging, the
battery is considered bad. Mark battery as "CHARGED, TESTED BAD."
4.
If at any time an "Unstable Battery" reading is received, use pliers and apply gentle force to make sure terminals
are snug with a clockwise turn effort. If any movement is experienced greater than an 1/8th of a turn in either
post, the battery is defective. Label battery as "DAMAGED" and dispose. DO NOT force posts to turn by
applying strong force.
5.
If a battery analyzer is not available proceed with charging the battery per instructions in (WP 0006).
