5 Tips For Buying Deep Cycle Boat Batteries

RSS

Deep cycle batteries are one of the most necessary pieces of equipment for boating enthusiasts, and there are a lot of different factors to consider when purchasing them. The good news is that you don’t really need to know a lot about batteries in general because there’s such a variety of easily accessible choices for all models.

To help you get started in selecting deep cycle boat batteries, here are five tips to consider:

1. Get the right size

The first step in buying a deep cycle battery is to make sure it will fit in your boat. The most common sizes for marine batteries are Group 27 and Group 24, although you may find other sizes as well. The battery needs to fit properly in the compartment and not be too heavy for the rest of the electrical system.

2. Find the appropriate voltage

Deep-cycle marine batteries have different amp-hours (AH) ratings, which determine how long they can run before needing to be recharged. For example, a 100 AH battery can provide enough power for about five hours at 25 amps. That same battery would only last about three hours at 50 amps. The more powerful your motor or electrical system is, the larger your battery needs to be.

3. Choose the right type of battery

If you need a deep cycle battery that can be used to power electrical equipment on a boat or RV, look for one labeled deep cycle or marine. These batteries are designed to withstand the frequent discharges and recharges associated with this type of use.

4. Look at the cold cranking amps

The cold cranking amps (CCA) value tells you how much power the battery can deliver at 0 degrees F (-18 degrees C) for 30 seconds before dropping below 7.2 volts. The higher the CCA number, the more powerful it is and the better it will perform in cold weather conditions.

5. Choose a reputable dealer

When you go to buy your deep cycle boat batteries, make sure that you get them from a reputable dealer who knows what they are doing. This will help you avoid getting ripped off with inferior products that may not last too long or, even worse, could be dangerous to use in your boat.
