harm.

WARNING - RISK OF EXPLOSIVE GASES

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 manufacturer as well.

2. To reduce the 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 precautionary markings on
these items.

12 Volt BATTERY ANALYSIS - Press “START TEST” & wait for 10 seconds.
Once automatic test cycle is completed, your test results will be:

1. GREEN LIGHT =
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 battery to fully charged level.

2. GREEN + YELLOW LIGHT = OK BUT WEAK): Review the load test result with
the comparison chart on the tester cover to see if this battery is “OK” or not. If
it is “OK”, go up to 1ST “OK” state. If it is not, go down to 3rd “WEAK” state.

3. YELLOW LIGHT =
either: (1) defective or (2) partially 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 fully charged level, the battery is either sulfated or has lost active material.

4. RED LIGHT =

OK): Battery capacity is good. May or may not be fully charged.

WEAK): Battery capacity is unsatisfactory. Battery may be

BAD): Battery may be defective (e.g. a bad cell).

NOTE: If pre-test battery voltage is below 12.3V, tester will not allow and

should not perform the load test. Please fully charge battery and retest.
