Warning: If you do not handle the battery properly, it may explode and cause serious injury to people nearby.
Follow all instructions carefully and keep sparks and open flames away from the battery.
Note: To obtain accurate test results, the electrolyte temperature should be between 21 and 38°C before testing.
Verification procedure
1. Check for damage: If the housing is cracked or the terminals are loose, replace the battery.
2. Check the color of the status indicator: blue or green indicates the normal state of the battery. If the indicator is red, remove the protective tape, remove the caps and add distilled water, then install the caps and tape. If the indicator is normal, go to step 3.
3. Connect the battery tester and set the load to three times the battery's amp-hour rating.
After the load has been applied for 15 seconds, the battery voltage should be at least 9.6 V.
If the voltage is above 9.6V, the battery is good, clean the terminals and case and install it on the vehicle.
If the reading is between 6.5 and 9.6 V, connect the charger and charge the battery with an initial current of 40 A for 3 minutes.
Warning! The current will decrease as the voltage increases. Do not try to compensate for the current drop by increasing it, you may damage the battery.
For all 3 minutes, observe the battery voltage, it should not exceed 15.5 V. If the voltage is less than 15.5 V, the battery is OK, clean its terminals and case and install it on the car.
If the voltage exceeds 15.5V during 3 minutes of charging, the battery is faulty and should be replaced.
If the voltage drops below 6.5 V, reduce the current and charge the battery at 5 A for no more than 24 hours (or until the charge is fully restored by the color of the indicator or until the electrolyte density is at least 1,270). After that, perform the load test again. o If the voltage is over 9.6 V, the battery is OK, clean the terminals and case and install it on the vehicle.
If the voltage is still below 6.5V, the battery is faulty and should be replaced.
