Best Deep Cycle Battery Reviews & Buying Guide Of 2021
Nowadays, everyone wants a constant power supply to fuel their homes, offices, and smart objects. In most cases, the power lines are present to deliver sufficient power to one’s home or home. The other side of things is that the requirement doesn’t end. One’s life revolves around many places and each location need not have power lines to supply constant power. A starter battery kit can help enhance the short burst of power but to get that consistent power source, one should get a deep cycle battery. These batteries can be used as the primary source of power to fuel RVs, generators, ships, and boats, and even forklifts. These deep cycle solar batteries or deep cycle RV batteries are convenient because they supply power for a long time before they require charging. The applications are wide-spread across many industries and one can make full use of it. It wouldn’t hurt to buy a deep cycle battery for people who like to travel or go camping. These batteries are reliable devices for many reasons. Deep cycle batteries are eco-friendly and they significantly contribute to proper discharge of waste. They can even perform heavy loads without overheating. The maintenance is very easy and one can store it even with less floor space. In this guide, some of the major types of deep cycle batteries and few features are addressed to consider before buying.
Types Of Deep Cycle Battery
Lithium-ion Battery
The best lightweight deep cycle battery is lithium-ion. These batteries are booming in the marketplace. Even though the weight is comparatively less, one can get high energy efficiency from this device. The life cycles for this battery can range anywhere between 3000 to 5000.
Flooded Lead-Acid Battery
This battery features a similar lead-acid chemistry but the difference lies in the plates submerged. The plates used for this battery are made of sulfuric acid and distilled water. Flooded batteries are usually unsealed and they come with high-surge current. The flexibility and compatibility of this design is a serious issue for many users. The designs and sizes are versatile, but the maintenance can be tough. People who are using this battery in a closed area should make sure it is ventilated with exhaust fans. The pressure inside is prevented to smaller value by venting out all volatile gases.
AGM Deep Cycle Battery
AGM deep cycle batteries are an excellent choice for small load activities. If one wants to install these batteries in their RVs and boats, then these are not suitable products. It has a robust power system that requires no extra maintenance. Overheating is not at all a problem because it can handle high temperatures. The ventilation is at a high level, and one doesn’t need to suffocate because it comes with low self-discharge rates. However, when these devices are overcharged, they can endure permanent battery damage. So, one needs to make sure that the battery is not quickly charged or overcharged.
Sealed Gel Battery
The electrolyte present in this sealed gel deep cycle battery is the main component. They come in both sealed and unsealed cases. It is better to go with unsealed because it can prevent leaks. Deep cycle gel batteries come in small sizes but they can perform heavy-duty operations with ease. The battery runs a quiet operation because it is resistant to vibration. Gel batteries can take up any activity at any given temperature. However, when the damage occurs, it is irreversible. Incorrect charging can be that deadly. Industrial deep cycle batteries work in the same fashion and they are commonly used for electric cars, mobile phones, and other expert applications.
Things To Consider Before Buying A Deep Cycle Battery
Battery Ratings
As these are environment friendly, they need to be properly assessed. One can take battery ratings as a parameter to check its power and energy efficiency. The usual ratings are labelled as “C”. It can be C10 or C100. The number after the letter signifies the reliability and lifespan of the battery. For example, if it's C20, it means that the battery can discharge for 20 hours straight before charging again. The rating capcity is usually given Amp hours(Ah).
Discharge Cycles
Energy storage should not be the only purpose when buying a deep cycle battery. Cycle rating is used to understand how many times the battery can be discharged and recharged. One needs to check the battery lines but make sure not completely to deteriorate the battery’s capacity.
Shock & Vibration Resistant
If one is buying a battery for their boat or car, they need to make sure that their battery can take a hit. The batteries will go through constant movement, so it should be shock and vibration resistant. If the battery is shockproof, one need not spend any money on repairs or servicing.
Temperature Regulation
Working at different temperatures is challenging, but it can be made easy when one buys a deep cycle battery that is susceptible to low and high temperatures. With temperature adaptability, one can continuously get power supply in any weather condition.
Lifespan
The maintenance and lifespan go hand-in-hand in the long term. For standard lithium-ion batteries, the lifespan can be up to ten years. Make sure to get in that range for high-quality batteries. One can check the previous users data to analyse and compare.
Price
Along with all the above mentioned factors, one should also consider size, weight, reliability, and functionality. Charging time can also make a significant impact on the final price. Some of the well known brands are Optima, Interstate, and Mighty Max. The price ranges anywhere between 120 Dollars to 350 Dollars.
Warranty
The warranty period is crucial when it comes to deep cycle batteries. A company is high-values when it gives extended warranty periods. So, look for at least a five years limited warranty period to get technical support and regular servicing.
Final Words
There you have it! Deep cycle batteries are versatile devices that are always ready to serve to any application. People who want to get constant power for their boat or RV should give flooded lead-acid battery a shot. If one wants a lightweight and high-performing battery, the best option is always a lithium-ion battery. However, if one wants to use the battery for simple and low power consumption devices, they should buy a AGM deep cycle battery.
