BASIC BATTERY LOAD TEST
(Conventional & Maintenance-Free Types)
1.Connect clamps to battery posts Red (+) Pos, Black
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).
