Types of Marine Batteries

Marine batteries come in various types, each designed for specific applications and needs. Here are the most common types:

1. Starting Batteries (Cranking Batteries):

   • Purpose: Designed to start the engine; delivers quick but powerful bursts of energy.
   • Characteristics: High cranking power, not suitable for prolonged energy supply.

2. Deep Cycle Batteries:

   • Purpose: Powers onboard accessories (like GPS, lights, and pumps) over a longer period.
   • Characteristics: Provides steady power output over extended periods; can be discharged and recharged many times.

3. Dual Purpose Batteries:

   • Purpose: Combines the functions of starting and deep cycle batteries.
   • Characteristics: Suitable for boats with limited space for two separate batteries but requires careful power management.
