Marine batteries are divided into three types:
1.Starting orcranking marine battery
These types of batteries provide high explosive power for short periods of time to start your engines and power your boat. When the ignition switch is activated, the starting boat battery supplies power to the engine. It is designed to deliver a large amount of current in a short amount of time. The AGM marine cranking battery has a larger number of thinner and larger surface area lead plates to provide the necessary power.
2.Deep cycle marine battery
If you want to power on-board electronics and accessories, deep cycle starting marine batteries are what you need. Deep cycle batteries produce less energy for a long time. It can handle long discharge cycles when the engine is shut down. Deep cycle starter batteries consist of fewer thicker lead plates to provide continuous power output over long periods.
3.Dual purpose marine battery
It is a hybrid battery designed to be used both as a starter battery and as a deep cycle. Dual purpose boat batteries are a hybrid of the two and are a good compromise between starter and deep-cycle batteries, especially for boats where only one battery is used for "home" power when starting and the engine is off.
Exor, as a well-known marine battery manufacturer in China, provides Dual Purpose Marine Battery which uses AGM technology and has lower internal resistance, allowing greater startup power and charging acceptance, and charging faster than other types of deep cycle batteries. AGM battery can accept the highest charging current, up to 40% of the battery's ampere-hour capacity, meaning they charge faster. Long life, low 3% self-discharge rate and excellent performance make EXOR's AGM batteries ideal for boaters who need fast start power and reliable deep cycle capability.
