How It Works

 The Ez Battery Check Cap

batterytesterillustration-04.pngThe Ez Battery Check caps provide an easy way to monitor the electrolyte level of your deep-cycle lead-acid batteries. A visible float indicator lets you know if your batteries are properly watered or they need filling.

The Ez battery check watering system caps allow the convenience to add more water without having to remove the cap from the battery.



What is a Deep Cycle Battery?

A deep cycle-battery differs slightly from your standard car battery. Deep-cycle batteries are a type of lead-acid battery. They are designed to be regularly discharged of the majority of their current capacity. On the other hand, standard automotive batteries are designed to give short, high-power bursts of current for cranking over an engine. Because of this, they frequently discharge only a small part of their overall capacity. A deep-cycle battery can be used to as a starter battery to crank over an engine, but because they carry a lower “cranking current”, an oversized battery may be required for the application.

To understand what makes the Ez Battery Check so important, first we must understand how a battery functions. A wet-cell battery is basically made up of a series of positive and negative conductive plates kept apart by separators. The negative and positive leads on the exterior of the battery are attached to the plates at either end of the battery.

To get the energy to flow between the plates and separators, an acidic electrolyte fills the battery. The level of this electrolyte is essential to not only the power capacity, but also the longevity of the battery.




How can I get the most out of my deep cycle battery?

The best way to keep up the life of your battery is by keeping it in the optimal discharge range. A deep-cycle battery is generally built to discharge between 50% – 75% of its total capacity. However, this range is dependent on how the battery is built, and the manufacturer. Deep-cycle batteries can be discharged down to about 20% of their charge, but they tend to work best when they are taken down to only 50% at lowest. This amount of charge ensures a longer life-span on your battery. Also, keeping the recommended amount of water-to-acid ratio in your battery helps to protect against a loss of overall max charge, and keeps your battery capacity at the factory 100%.
