What must be done on a carbon pile battery load tester before connecting it to a battery?
Ensure the battery load tester dial (4) is in the OFF position (rotated anti clockwise as far as possible) before attaching or removing the RED (+ positive) battery clamp (5) or BLACK (- negative) battery clamp (6) to prevent arcing or potential explosion from battery gasses.
How do you read battery results?
Once the battery is fully charged, it can be tested to determine whether it is good or bad. Most auto parts stores will do this for free….Battery voltage readings are as follows:
- 12.66 volts = 100% charged.
- 12.45 volts = 75% charged.
- 12.24 volts = 50% charged.
- 12.06 volts = 25% charged.
- 11.89 volts = 0% charged.
When load testing a battery the load applied to the battery should be?
The Load Test requires a high rate discharge tester to be connected to the battery. The load should be set to 1/2 the Cold Cranking Amps (CCA) or 3 times the Amp-Hour rating. The load should be applied for 15 seconds and the voltage should not drop below 9.6V (at a battery temperature of 70°F or 21°C).
What must be done to the ignition system before a battery load test is performed?
Vehicle Battery and Load Testing

What should alternator voltage be under load?
A good alternator should maintain battery voltage between 13.9 and 14.8 volts (14.2 is optimum). Even worst-case, with all accessories turned on, there should be at least 13 volts at the battery.
How do you know if a battery is fully charged?
Check the voltage of your battery using the voltmeter to help determine your next course of action. 12.6V volts or above – Your battery is healthy and fully charged.
Do I have to disconnect battery to load test?
If your load tester is electronic, it will automatically remove the surface charge before conducting the load test. However, if your test equipment is manual, you will need to remove the surface charge yourself by applying a 300-amp load for 15 seconds.
When performing a battery load test what should the load be set to?
The Load Test requires a high rate discharge tester to be connected to the battery. The load should be set to 1/2 the Cold Cranking Amps (CCA) or 3 times the Amp-Hour rating (whichever is labeled on the battery).
What is a good battery load tester?
Editor’s Choice: Topdon BT100 Car Battery Tester Its load tester can check the 12V charging system, ensuring the output voltage is within spec and the charging current is with normal range.
