How To Test A Marine Battery Charger?

If you rely on your car's batteries, the last thing you want is to leave them on the charger all night only to find they're not charging. This may prevent you from driving in the morning.

If your battery dies unexpectedly or doesn't seem to hold a charge, you may initially suspect the problem is the battery itself. But have you considered checking out your charger?

In fact, charger problems are an often overlooked cause of electrical failure in your car. So what can you do about it?

Is there any way to test your charger?

Several, actually.

1. Connect the charger to the battery and ensure the voltage is correct and the charger is securely attached.

2. Check that the amperage output of the charger matches the battery’s requirements.

3. Ensure all terminals are clean and free of corrosion.

4. Turn on the charger and monitor the charge rate, checking for any abnormal readings.

5. Monitor the voltage and amperage output at different charge levels.

6. Check the charger’s temperature to ensure it isn’t getting too hot.

7. Monitor the battery’s voltage and temperature.

8. Once the battery is fully charged, disconnect the charger and monitor the battery’s voltage.

9. Run a load test to ensure the battery is able to hold a charge.
