On board charger is a great investment for any car or motorhome owner, providing increased convenience and cost savings. However, if you want to make sure your charger is running in optimal condition, you need to perform regular maintenance. Here are a few tips on how to properly maintain your on-board charger:

Clean Connections - To ensure the most effective charging session, make sure all connections between your battery and charger are clean and free from dirt, dust or corrosion. You should also check regularly for any signs of wear and tear that need replacing.

Temperature Control - Environment can have an impact on charging efficiency levels, so make sure to consider both temperature and humidity when selecting your charger – some models come with temperature control options that can help optimize performance in different climates.

Monitor Performance - Check your charger’s performance regularly by monitoring current draw during charging sessions as well as any fluctuations in the output voltage or amperage over time – this will help identify problems early before they become bigger issues.

Keep It Dry - Make sure your battery and charger stay dry while in use – moisture can lead to damaging corrosion which will reduce efficiency levels over time as well as cause potential safety issues such as electric shocks or fires!

Usage Guidelines - Follow all usage guidelines provided by the manufacturer regarding how many amps you should be using during charging sessions – this will help ensure optimum efficiency while minimizing potential risks of overcharging or damaging your battery’s cells due to excessive current draw.

By following these simple tips you can keep your on board charger running optimally for years to come!
