Things to Consider While Buying the Good Deep Cycle Marine Battery

Either you are a fishing enthusiast or water sports enthusiast; you need to make smart choices when it comes down to buying a battery for your boat or other marine appliances. One must agree that while a buying a product, there are many factors that need to be considered other than being swayed by the prices or users’ reviews. Here we have created a list of important things that you should definitely consider and analyze while buying the best deep cycle battery as per your need.

  • Size:

The first and the foremost thing that you need to check while buying a deep cycle battery is the size. You might need the battery for multiple uses, but make sure that all these applications need a specific size of the battery. If you have a bigger boat or a marine appliance which needs higher voltage and power to work, then go for the large battery. However, go for the smaller size, if you have a small boat and less voltage devices to operate. Moreover, a smaller sized battery is very mobile and can be easily carried from hither to thither.

  • Vibration resistance:

When the word vibration is used in regards to marine appliances, it is pretty clear that these tremors will be caused if you take you boat on rough waters. In that scenario, you must check the level of resistance provided by your battery against these vibrations and shuddering. The higher the level of resistance, the more is the durability of your battery even under extremely harsh conditions.

  • Reserve Capacity:

Another important factor which must be taken under consideration is reserve capacity. By reserve capacity, the time period for which a battery can be used continuously is defined. Thus, if there are prospect of you staying on the boat in water for longer period of time, then buy a battery with higher reserve capacity. This is because the last scenario you want to face is being stuck in waters because your battery was worn out

  • Lifespan:

There is difference between reserve capacity and the lifespan of a marine battery. When we talk about lifespan of a battery, we talk about the durability of the battery in the long run. Most of the manufactures promises the long lifespan of the battery, but you must not be easily baffled. Always take help of the users’ reviews and also see if the product is covered under longer period of warranty or replacement.

  • Wet-cell batteries v/s AGM batteries

If you are a lazy sloth who doesn’t want to go under the strain of maintenance of a battery, then go for the AGM batteries. The AGM stands for the absorbed glass mat which excludes the hassle of adding water again and again to battery in order to maintain the composition of electrolyte.

The wet-cell batteries should be preferred if you want to employ the battery for multiple use. This is because these batteries are designed to endure the constant series of charging and discharging. But, one needs to replace these batteries within a time period of 1-2 years which is quite less as compared to AGM batteries

Both the batteries have their own perks, you can choose the right one as per your needs.
