Best Deep Cycle Battery 2020

When you need a larger battery to handle the powering of equipment rather than devices, you will need to consider how a deep cycle battery can be used to suit your needs.

The biggest difficulty in buying the best deep cycle battery is really knowing where to start. We are not all battery experts and there are things to consider about the specifics of how the battery will be used. To help you sort through all of the details that need to be taken into account, we have developed some tips and information to get you closer to making the right selection.

Things to Think About

What will you be using the deep cycle battery for? These batteries are most commonly used for providing power to equipment like golf cars, boats, RVs and even solar panels. The machine you need to power will determine the type of battery that you need.

The Types of Deep Cycle Batteries

The types of batteries include a true deep cycle and an RV or marine deep cycle. These are best used in different situations.

  1. The True Deep Cycle Battery is generally used for domestic purposes like providing the power in an RV for appliances. This type is also best used for solar panels and storing energy because it can deal with more recharging cycles.
  1. The RV or Marine Deep Cycle Battery is a hybrid made up of features of a cranking battery and a true deep cycle. This is best used for getting boats started and even for running the lights and electrics when it is anchored. Although this is a reliable choice it sacrifices some of the qualities of the styles it has become a hybrid of and its lifetime is much shorter.

One Extra Note

In our list of the top ten deep cycle batteries, we have supplied information on each item’s amperage rate. Essentially this is a control test on how long the battery took to drain to zero from a full charge. The test has a lot of complicated details but basically the higher the number of amperage hours (Ah) the longer the battery will last.

Features of Good Deep Cycle Batteries

The best deep cycle battery is the one that has all of the great features of this kind of battery working in the most efficient way possible. This type of battery is used for powering electrical equipment for longer periods of time so the best one is the one that can provide the most power and has the most extended lifetime.

  • Recharging. Unlike a starter battery, a deep cycle battery can be recharged which is what makes it best for usage with solar panels. The sun charges the battery during the day and the energy can be released all through the night.  Being able to recharge many times and also release the energy slowly over time is key to the effectiveness of using the deep cycle battery in this way.
  • Bonus Feature. As a starter battery is often used as a comparison it is important to note that a deep cycle battery can be used to start a car if necessary but a starter battery cannot be used in the same way as a deep cycle is used. This added benefit and versatility is something you should look for in the best deep cycle battery.
