LOAD TEST
BATTERY CONDITION
OK (GREEN BAND).
After 10 seconds of load.
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 possible charging
system trouble or electrical drain. Recharge bat
-
tery to full charge.
WEAK OR BAD, BUT STEADY (meter reading
steady after 10 seconds of load).
Battery capacity is unsatisfactory. Battery may
be either: (1) defective or (2) partly dischar
-
ged. 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.
WEAK OR BAD AND FALLING (meter conti
-
nues to fall after 10 seconds of load).
Battery may be defective (e.g. a bad cell). For
a quick check, release load switch and note volt
meter reaction. If voltage recovers to 12.0 volts
or more in a few seconds battery is probably
defective. If voltage recovers slowly, battery may
be only very run down. For more accurate re
-
sults, check gravity and follow above procedure.
WARNING - RISK OF EXPLOSIVE GASES
Pursuant to California Proposition 65, this product contains chemicals known to the State of Califor

1.
Working in the vicinity of a lead acid battery is dangerous. Batteries generate explosive gases
during normal battery operation. For this reason, it is of utmost importance that each time before
using your tester, you read these instructions carefully and follow instructions by battery maker as
well.
2.
To reduce risk of battery explosion, follow these instructions and those published by the
battery manufacturer and manufacturer of any equipment you intend to use in the vicinity of the
battery. Observe cautionary markings on these items.
