Deep Cycle Battery Buying Guide

With so many deep cycle batteries being offered on the market, you need to choose the best deep cycle battery for your needs and applications. For this to happen, you need to know the different types of deep cycle batteries available, what features to look for, and how to differentiate a good battery from a bad one. This review helps you make an informed choice.

Types of deep cycle batteries

There are different types of deep cycle batteries and they are as follows:

  • AGM batteries

AGM in full means Absorbed Glass Mat. This is the most preferred deep cycle battery on the market. The battery is very efficient in performance as it improves the discharge and recharge capabilities of the battery. AGM batteries are similar to VRLA batteries, with the only difference being that they are more advanced.

  • Sealed Lead-Acid batteries

Another popular deep cycle battery is the sealed lead-acid battery. This is also a very popular type of battery and it is also referred to as Valve Regulated Lead-Acid (VRLA) battery. This battery produces energy through the utilization of oxygen and nitrogen. These batteries are normally vibration and shock resistant because they have a gel inside.

  • Flooded Lead-Acid batteries

Flooded lead-acid batteries are slightly different from the first two batteries as they are unsealed and feature a container with distilled water and acid. Because of this, this battery needs regular maintenance and it can spill. However, this battery delivers great power which is ideal for high-end needs.

  • Lithium-ion batteries

Lithium-ion batteries are the most recent on the market. These batteries are great at saving energy and delivering great power output. They are also extremely durable and can withstand different weather conditions. Above all, these batteries are lightweight. However, they are also costly and hard to find.

  • Gel batteries

Gel batteries are very expensive thus not many people cannot afford them. These batteries are costly because they are durably made. In addition, they are great at resisting both shock and vibration. That’s why they are preferred for marine and aircraft. Unlike other battery types, Gel batteries don’t need any maintenance and can resist both very cold and very hot temperatures. The only challenge with this battery is that they have a lower amount of power.

What to consider when buying deep cycle batteries

  • Size and weight

When choosing a battery, consider its weight and size. A small battery will usually weigh less and won’t be a burden when you install it in your RV, boat, or even a golf cart. But you should always consider your battery compartment size before purchasing a battery.

  • Amp-hours

Amp-hour rating is important as it determines how long the battery will last before having to be recharged. Most batteries last for at least 3 hours with some gong for even 10 hours or more. Take your time and pick the right battery for your activity.

  • Voltage

Voltage indicates how much power is present for use. For most automobiles, electrical equipment, and boats, a 12V battery is just fine. But for high-end use, a 24V or 36V will be the best option.

  • Vibration and shock-resistant

A good deep cycle battery should be able to handle vibration and shock or it will deteriorate quickly. That’s why get a sealed battery that doesn’t leak or spill is vital.

  • Performance in extreme conditions

Some batteries may fail to perform in extremely cold or hot conditions. Find out if the battery performs well in your environment. Most deep cycle batteries will deliver great power in both extremely cold and hot environments.

  • Charge time

How long does the battery take to recharge? A good battery should not take more than 4 hours to recharge. Some batteries take up to 8 hours or even 24 hours to fully recharge. This can be quite challenging, especially if you intend to use the battery on a daily basis.

  • Warranty

Don’t just buy from any brand as some brands are not reliable. Consider buying not just the best deep cycle battery on a budget but it must have a proven track record and warranty.

Conclusion

Even though there are many deep cycle batteries to choose from, ensure that you select a battery that serves your purpose and is within your budget. Some batteries are great for RVs, boats, solar grid, automobiles, and golf carts, while others are more suitable for high-end use. Our list above features some of the best deep cycle batteries on the market. I hope you’ve found a battery of your choice and budget.

FAQ

Question: What is a deep cycle battery?
Answer: This is a battery that is designed to be repeatedly deeply discharged from the majority of its capacity to provide steady power over a long period. Unlike car batteries or starting batteries, deep cycle batteries usually discharge a majority of its capacity without damaging itself. Also, these batteries give a consistent stream of energy which starting and traditional batteries

Question: Is an AGM battery a deep cycle battery?
Answer: AGM batteries are deep cycle batteries. Actually, AGM batteries are one of the types of deep cycle batteries. Other types include gel batteries, lithium-ion batteries, and flooded batteries. AGM batteries are the most preferred type of deep cycle batteries because they are low maintenance. Some types of batteries require adding water and some other liquids. With AGM batteries, you won’t face such challenges and that’s why many people prefer them.

Question: What should I do to get the best performance out of my deep cycle battery?
Answer: Deep cycle batteries can last even longer when well-maintained and utilized. If you want to get the best performance out of your deep cycle battery, here are some of the tips to follow. The first thing to do is always to check the charge. Always charge the battery before its charge level is below 50%. Secondly, after using the battery for long and recharging it, allow it to rest and cool down before reusing it. Another thing to do is to prevent battery sulfation. When left unchanged for over a long period of time, the lead may sulfate and get crystallized. This prevents the battery from holding thus you should charge your battery from time-to-time even if it’s not in use.

Question: Is it okay to overcharge a deep cycle battery?
Answer: No, it is not. Overcharging and undercharging a deep cycle battery lowers its durability and performance. Yes, you can overcharge the battery but you will greatly lower the overall capacity and lifespan of the battery. As a result, you should avoid overcharging to get the best out of the battery. One of the ways to prevent overcharging the battery is to purchase the most ideal charger for your unit. Also, when the weather is hot, lower the charging voltage a bit. This is because warm batteries take to power more quickly.

Question: How many years will my deep cycle battery last?
Answer: This depends on the type of battery. Since deep cycle battery features different battery types, the durability of the battery will vary from one battery to another. For instance, AGM batteries last between 4 and 7 years. Note that the materials and construction of the AGM batteries also differ from one brand to another. Some battery models will last for less than 3 years while others may last up to 10 years.
