Lithium-ion batteries are an ideal choice for applications that require lightweight and high-performance power solutions.

How do leisure batteries work?

1. Electrochemical Reactions:
   • Leisure batteries operate based on electrochemical reactions. These batteries consist of multiple cells, each containing positive and negative electrodes. The electrodes are typically made of different materials, such as lead and lead dioxide in lead-acid batteries or lithium compounds in lithium-ion batteries. The electrodes are immersed in an electrolyte solution, which facilitates the movement of ions.
2. Discharging Process:
   • When a load, such as an appliance or device, is connected to the battery, a chemical reaction occurs at the electrodes. This reaction causes the flow of electrons from the negative electrode (anode) to the positive electrode (cathode), generating an electric current. Simultaneously, the electrolyte allows the movement of ions between the electrodes, balancing the charge and completing the circuit. This discharging process converts the stored chemical energy into electrical energy, which powers the connected load.
3. Recharging Process:
   • To recharge a leisure battery, an external power source is connected to it. During the recharging process, the electrochemical reactions are reversed. The external power source applies a higher voltage than the battery’s voltage, causing the flow of electrons to reverse. This reverses the chemical reactions that occurred during discharging, restoring the battery’s chemical energy for future use. The recharging process prepares the battery for subsequent discharging cycles.

Benefits of using a leisure battery
