Tip on How to Use a Deep Cycle Battery Properly

Deep cycle batteries are created to give you long-lasting support. Hence, you will enjoy a longer power time for most of your devices. However, deep cycles require steady but not so difficult maintenance techniques to give them a long lifespan. These simple maintenance techniques include:

1. Charge Periodically

One of the best ways to give your deep cycle batteries the lifespan they are created to have is to give them a routine charging. Even when your battery is not in use, there is a need to give them that periodic charging the battery needs to prevent sulfation.

At the point of sulfation, the battery is already bad, and there is no point in trying to revive it. This happens especially with lead-acid batteries. If this kind of battery is left for a long time without being charged, the lead sulfates will begin to crystalize, and this causes the battery plates to crack. Hence, ensure you charge your batteries periodically as some sort of maintenance hack.

2. Allow Your Battery to Rest

Just like your body, it is important to allow your battery to rest. It is not so healthy to put your battery to immediate use after a deep cycle charge neither is it good to run your battery while charging. Hence, whether for your solar grid, wheelchair, golf cart, or any other machine where a deep cycle battery is needed, it is important you allow your battery to cool off, after a charging cycle, before putting them to use.

Failure to do this, you may burn your battery out and may also cause a serious internal heat generation that may cause grid corrosion and render the battery weak. This may result in total battery failure or may cause you to experience your battery not working at its optimal level.

3. Keep the Battery Cells Balanced

The inability to keep your battery cells balanced may result in total battery failure or battery instability. Deep cycle batteries are best enjoyed when optimally charged. Hence, when trying to balance your battery cells, you need to perform a periodic equalization exercise. This means extending the full charge cycle by three hours, under a low current charge. This will ensure your battery doesn't experience any dip in cell irregularity.

Conclusion

When you consider deep cycle batteries as a great investment, then any of our 9 best deep cycle batteries become the options you want to choose from. These brands have been carefully evaluated and analyzed by our top experts in terms of functionality and heavy-duty advantage.
