Marine batteries: Properties and How Does It Work
The marine battery is a DC power source. It works on the same principle of a conventional rechargeable electrolytic battery. However, the marine battery also has qualities that make it a powerful power source, which adapts well to the requirements of the user and the constraints of marine navigation. Today we are learning about: Marine batteries: Properties and how does it work…
How does a marine battery work?
A conventional battery is an assembly formed by two electrodes of different chemical nature, which dip into an appropriate electrolyte. When these electrodes are connected to an electrical receiver, an electric current flows from the pole () towards the (-) pole of the battery. This current results from a chemical oxidation-reduction reaction, between the electrolyte and the electrodes. The discharge of the battery is then started. Using a battery charger will recharge the battery. The marine battery also works on the same principle of the classic battery. However, the marine battery is designed using advanced technologies to meet other requirements. It must support the marine environment. Like.
- Waterproof and free from any discharge.
- Have an adjustable electrolyte level
- Have a low level of gassing
- Have a suitable lifetime.
- Have good vibration resistance.
- To be able to serve at the same time the servitude and start if it is necessary.
The choice of a marine battery depends on its technology. Three main families of marine batteries are:
- Liquid marine battery
- Marine battery AGM
- Marine battery GEL
Properties of marine batteries
The best marine battery is characterized as durable and slow discharge. It can undergo several discharge-recharge cycles, unlike a conventional starter battery. Marine batteries have much longer battery life and durability when properly maintained, especially when they are carefully recharged with a suitable charger such as the Minn Kota charger for example.
The AGM battery is perfectly waterproof. It has the advantage of accepting large charging and discharging currents. It has a better value for money and in the long term, its cost is amortized compared to a conventional liquid battery.
The Gel battery has the ability to discharge at 100% without recharging it immediately. It is resistant to a greater number of cycles, this difference is marked when the discharge depth is high. The performances of the AGM and GEL marine batteries are comparable considering that technology differs.
