On the other hand, sealed deep-cycle batteries, also known as valve-regulated lead-acid (VRLA) batteries, are maintenance-free and do not require checking or refilling electrolyte levels. They are completely sealed, preventing any leakage or spillage.
Recognizing the Signs of a Flooded Lead Acid Deep Cycle Battery
Recognizing the signs of a flooded lead acid deep-cycle battery is crucial for maintaining its performance and avoiding costly damage. One of the most obvious signs is a low battery voltage, which can be measured using a voltmeter. If the voltage is significantly lower than the battery’s rated voltage, it could indicate the battery is flooded and not holding a charge properly.
Another sign to look out for is excessive heat coming from the flooded lead acid deep cycle battery during charging or use. This could result from internal short circuits caused by the build-up of sulfuric acid, a common issue in flooded batteries.
If you notice a strong rotten egg smell or corrosion on the battery terminals, it may indicate that the battery is flooded and the electrolyte leaks. Suppose the battery consistently fails to provide enough power to run your electrical devices or quickly loses its charge even after a full recharge. In that case, it may signify a flooded deep-cycle battery.
