Which method helps to prolong the lifespan of marine batteries?

Maintaining water levels is essential for prolonging the lifespan of marine batteries, particularly for flooded lead-acid batteries. These batteries rely on a fluid electrolyte, and if the water levels are not checked and maintained, the electrolyte can become too low, leading to sulfation and damage. Regularly topping off the water with distilled water ensures that the electrolyte remains at the optimal level, allowing for efficient operation and preventing premature failure.

In addition, maintaining proper water levels helps to prevent overheating during charging, which can further degrade battery performance. Consistent maintenance of water levels, along with proper charging practices, helps to ensure that the batteries hold their charge effectively and have a longer and more reliable service life.
