What to Consider Before Buying a Marine Battery Charger
Before purchasing a marine battery charger, here are a few things you should think about.
Durability
First and foremost, you don’t want to skimp on the quality of your charger. You need to make sure you find a durable charger that has waterproof protection and can withstand shocks.
Battery Coverage
Not every charger will be compatible with your type of batteries. It is essential that you find a charger that will effectively read your battery and be able to tell when it is nearly done charging to avoid over-charging. This also means finding a charger with the right amount of voltage. You’ll likely either need a charger with 6V and 12V or one with 24V and 48V.
Charge Time
How long it takes to charge your battery will depend on its size. However, the more powerful your charger is, the quicker it will charge your battery. Check the charge time of any charger you’re considering to make sure it is compatible with your needs.
Power
You’ll want to see what the required power source for your charger is. If you typically leave your boat overnight, you don’t have to worry about finding a specific one that needs a shore power unit. You can also look into portable chargers.
Safety
To ensure you don’t cause harm to yourself or others, there are a couple of features you’ll want to look for in your battery charger. You’ll want protection from overheating, over-charging, voltage, and current. This is especially essential if you will be leaving your charger and battery unattended.
