Blue Sea Systems Tech Tip: Battery Charging Explained
Learn all about how charging a boat battery works.
There is a certain art to charging a boat battery that requires correct timing above anything else. Charging the battery is similar to the concept of air pressure, when air is blown into a balloon - the more pressure you blow into the balloon, the larger the volume in the balloon becomes. Likewise, the more electricity that is charged to the battery, the greater the amperage volume will be.
Batteries are charged by applying varying levels of voltage/electrical pressure to the battery itself. The process of charging batteries amplifies the voltage to higher levels than what a normal battery has. The energy charge flows into the battery and creates a chemical reaction. That saves the energy, such that, the chemicals form until the time when extra power is required, at which, it will turn into electrical energy. Again, timing is crucial when charging batteries.
There are three main levels of battery charging that decrease or increase in intensity:
Protecting Your Boat's Alternator and Battery Systems
There are certain important precautions you will want to follow in order to preserve the internal circuits and systems in your boat.
Step 1: Choosing a Wire
Identity where the current flow is located in your circuits.
Choose the circuit type.
Non-critical: consitutes at least a 10% voltage drop, which covers all general appliances, general lighting, etc.
