Choosing a reliable cranking battery for your bass boat is important since your fishing trip won’t even begin without it.
A good cranking battery should provide you with the power you need in different weather conditions.
If you’re unsure where to start, continue reading to learn more about cranking batteries and which one should you get for your bass boat.
Cranking Battery vs Deep Cycle Battery
A cranking battery is used to start the engine of your boat. It gives strong bursts of energy to ignite the engine and move the boat.
The bigger the plate surface area in the battery, the easier it is for the battery to provide sufficient power.
This is the reason why cranking batteries have multiple thin plates, to maximize surface area and make starting a boat as reliable and smooth as possible.
Once you start your boat’s engine, you no longer need those powerful energy bursts. Instead, you need continuous power for trolling.
That’s the exact purpose of deep cycle marine batteries.
They consist of thicker and fewer plates than cranking batteries, allowing them to deliver continuous power output over an extended period of time.
There are dual-purpose batteries that are designed to work as both cranking and deep cycle batteries. However, these batteries may not be the best option for your boat.
They don’t necessarily allow your boat to perform at the same level as having two separate batteries. Moreover, they’re more expensive than dedicated cranking and deep cycle batteries.
If you already own a reliable deep cycle battery, it’d be more economical to get a dedicated cranking battery.
How to Choose the Best Cranking Battery for Your Bass Boat?
Here are a few tips to help you select the suitable cranking battery for your bass boat.
Ampere hours is the measurement unit of marine batteries’ capacities. A capacity of 100Ah means that your battery will provide your boat with that value for one hour.
Obviously, the higher the capacity, the longer your fishing trips will last.
The reserve capacity is expressed as the number of minutes it takes for the battery to discharge at a steady rate of 10.5V by 25A at 80°F. A higher rating is better because it means your battery won’t die quickly under load.
It’s important to know that it’s a theoretical value and in reality, the battery will likely draw less amperage at a different temperature, giving you longer battery life.
Acid spilling is a big problem with marine batteries. You should consider getting a battery that’s designed to be spill-proof. Check the specs of the battery to know whether it’s spill-proof or not.
Dimensions & Weight
Size and weight can be an issue on bass boats, especially because they’re limited in size. A bigger battery usually has a higher capacity.
It’s better to get a battery with just enough capacity for your boat’s requirements. You can check the battery’s specs and see if they’re compatible with your boat’s design.
Portability is another factor to consider, especially if you usually need to move the battery.
