Maintenance tips for best marine batteries for solar panels
The best marine batteries for solar panels are complexly engineered to withstand the turbulence that occurs in boats.
They are therefore much more expensive than automobile batteries. Furthermore, it is never advisable to use a car battery to power your boat, as this can damage the battery and even your boat.
Types of best marine batteries for solar panels
Marine batteries can be broadly grouped into three categories:
- Marine Starting Battery: This type of battery is mainly designed to ignite the boat’s engine. The mechanism of the onboard alternator is designed to rapidly recharge the battery. Therefore if you wish to power your appliances or troll motors, it is advisable to get another battery, as starting batteries are not designed for these purposes.
- Marine Deep Cycle Battery: This type of battery is ideal for powering onboard appliances like audios systems, thrusters, fish locators, and so on.
The battery can withstand hundreds of charging and discharging cycles because it is designed to discharge slowly over a long period.
- Marine Dual Purpose Battery: This type of battery saves both cost and space as it combines both deep cycles and starts in its performance.
You do not need to have two separate batteries for starting your boat and powering your onboard appliances.
However, you must note that a dual-purpose battery cannot totally match the single performance of starting or deep cycle batteries.
Replacing the best marine batteries for solar panels
You must ensure you purchase a battery that works properly for your boat when you go shopping for a new battery.
Your boat owner’s manual would be helpful in making the right battery choice for your boat. You could also consult a marine dealer for battery options for your boat.
When making a choice it is important you pay attention to battery ratings like marine cranking amp, amp hour rating, and reserve capacity.
When replacing a starting battery you should take into account the particular note of the marine cranking amp and ensure it fits your boat’s engine specifications.
However, if you are shopping for a deep cycle battery you should consider the reserve capacity and amp hour rating.
For a dual-purpose replacement battery, you would have to consider all three rankings.
Tips for Preventing Battery Problems
Your marine battery would eventually develop problems no matter how properly you maintain it.
The good news, however, is that you can keep it functioning properly and extend its lifespan for as long as possible. Here are some basic steps to follow.
Although you may not use your both regularly, it is important that you get it into the water often to exercise the electrical system. This is an easy way to extend the lifespan of your battery.
You should get a maintenance-type charger as it is ideal for keeping the boat fully charged when it is not in use. If you are the type who rarely uses their boat, you should seriously consider getting this type of charger.
It is important that you charge your marine battery before storing your boat for the off-season. Also, make sure to disconnect both terminals to prevent drainage of any sort while in storage.
It is also recommended that you keep a tray specifically for that purpose. It must be firmly screwed to the boat with a locking strap to keep it in place to prevent it from coming loose when the boat encounters rough waters.
Make it a routine to regularly check the terminal connections because wear and tear are bound to occur due to the vibrations and banging the boat experiences in the water.
The terminal must be tightly connected and free of corrosion.
It is also important to ensure that the positive terminal of the battery is covered, and if it is not, you must install a cover whether the battery is inside a covered box or not.
A terminal cover prevents arcing sparks and even explosions.
