BASIC BATTERY LOAD TEST

(Conventional & Maintenance-Free Types)

1. Connect clamps to battery posts Red (+) Pos, Black
(-) Neg and note the battery’s capacity. Engine and all
electrical accessories must be off when testing battery.

2. Hold load switch “on” for 10 seconds.

3. Read meter with load still on then refer to battery
analysis table on back of Tester.

COLD TEMPERATURE EFFECTS

A battery will test lower when cold than when warm. For
more accurate results, please reduce the battery’s nominal
rating by 200 cranking amperes (one step on meter scale)
for each 20°F drop below 40°F. If cranking ampere rating is
800 and battery temperature is 0°F, test as a 400 cranking
ampere battery (i.e. 2 steps down).
