Deep Cycle, Dual Purpose, and Starting Marine, Vehicle and Solar Batteries and Chargers

dual purpose exide battery 1Lead-acid marine batteries are a very important piece of equipment, regardless if you have a small boat that can be pulled out on dry land by hands, or you have large vessel suitable for long off-shore fishing trips.

Today, there are several battery types that are used on fishing boats: Lead Acid batteries, Nickel-Cadmium batteries, Nickel Metal Hydride batteries, Lithium batteries, etc.

Non-lead acid battery types do have their advantages, but so do the lead-acid batteries and they are still the most used marine battery type.
