This guide will teach you in-depth about deep cycle batteries, their key features and functions, critical types of deep cycle batteries, 5 top deep cycle batteries, and more details. Let’s get down in detail!

Part 1. What is a deep-cycle battery?

A deep-cycle battery is a type of battery that can sustain power for an extended period. In this case, these batteries are highly suitable for regular discharging and recharging applications.

Key features:

  • Provides a steady flow of power over a long period. Hence, it is highly suitable for renewable energy storage, electric vehicles, golf carts, marine vessels, and RVs.
  • Deep cycle batteries can be discharged to a lower level than conventional batteries. Also, they have the power to handle 80% of discharge.
  • It has a longer lifespan since it consists of thick lead plates and unique compositions.
  • It comprises various chemistries such as flooded lead-acid, sealed lead-acid (AGM and gel batteries), and lithium-ion.

Key functions:

  • Ability to store electrical energy generated from solar panels or wind turbines.
  • They are considered a suitable power source for electric motors and devices handy for applications such as golf carts, forklifts, trolling motors, and RV appliances.
  • They are considered backup power sources when used to maintain uninterrupted operations.

Part 2. Types of deep cycle batteries

The following are the main types of deep-cycle batteries:

  • Flooded Lead-Acid Batteries (FLA): They are the commonly used traditional type of deep battery consisting of electrolytes.
  • Sealed Lead-Acid Batteries (SLA): SLA is also known as Valve-Regulated Lead-Acid (VRLA) batteries. These batteries are available in two main types: Absorbent Glass Mat (AGM) and Gel batteries.
  • Absorbent Glass Mat (AGM) Batteries: The AGM battery uses a fiberglass mat. A fiberglass mat helps absorb electrolytes and has a high power density.
  • Gel Batteries: Gel batteries consist of silica gel electrolytes providing high resistance features to even extreme temperatures.
  • Lithium-Ion Batteries: Lithium-ion deep-cycle batteries use a new technology. Hence, they have a high energy density, making them practical for users.
