A Deep Cycle Battery is the battery that user can charge and discharge again and again without posing much damage to the cells of the battery. It is a kind of lead-acid battery, intended to discharge between 45% and 75% of its inbuilt capacity. Deep Cycle Batteries are the vital part in different types of renewable energy systems, which require electricity to be stored for future use.
The basic structure of Deep Cycle battery includes thicker active plates, to save the battery from corrosion through extended charge-discharge cycles. Alloys (metal made by combining two or more metallic elements) are used as plates in a deep cycle battery.
Uses of Deep Cycle Battery
a) Marine use
b) In recreational fishing boats
c) Motorized wheelchairs
d) Recreational vehicles
e) Off-grid energy storage systems for solar power or wind power
f) Industrial electrically-propelled forklifts and floor sweepers
g) UPS for computers
h) Traffic signals
i) Power for instruments or equipment at remote sites
j) In certain audio equipments
k) Traction batteries to propel vehicles like golf carts, etc.
How a deep cycle battery works?
Just like any other battery type, Deep Cycle battery is comprised of three basic components: cathode, anode and the electrolyte. The chemical reaction that happens inside the cell creates a buildup of electrons in the anode, at cathode electrons are reduced under electrochemical reduction (a chemical reaction that causes the transfer of electrons between molecules). The chemical reactions taking place at either electrode create an imbalance in them, thus creating a flow of current known as the electricity/power in a battery.
Tips to maintain your Deep Cycle Battery
a) Make it corrosion free
b) Make use of mineral water to keep the fluid level at correct amount
c) Regularly test the charge
