One class: 3 hours
Do you have enough battery power and are you charging your batteries to maximize their performance? Many people understand the concepts but few have the information to make their boating experience worry free.
Batteries do not make electricity; they store it, just as a water tank stores water for future use. As chemicals in the battery change, electrical energy is stored or released.
Did you know that a natural battery occurs when two dissimilar metals are placed in contact with each other while immersed in an electrolyte? And that seawater is a perfect electrolyte for metals creating galvanic corrosion? This is one kind of battery you donít want around your boat.
Learn from the best: Mike Saylor. This fast-paced workshop is short on theory and long on practical guidance covering operation, maintenance and trouble-shooting your marine battery needs and how to prevent galvanic corrosion. This class focuses on do-it-yourself maintenance, what you need to be worry free and basic trouble-shooting.
- A QUICK OVERVIEW OF BATTERIES how they work and the different kinds: dry, wet, gel and AGM. The pros and cons of each type, and the risks (charging/discharging rates). How they can be hooked up (series vs parallel). Discharging and charging cycles and the effect of discharging (What happens when a battery is discharged/overcharged).
- ALTERNATORS and their effect on the different battery types (voltage vs amperage) Internally vs externally regulated alternators (automotive vs marine). How big should your alternator be?
- Volts, amps and resistance.
- The electrical budget. It's got to be balanced. Matching your batteries and alternator to your needs.
- Sailboats vs powerboats.
- # Generators vs Inverters - the power must come from somewhere. Inverters don't provide free power.
- Establishing your power requirements etc.
Topics covered about galvanic corrosion
- What causes galvanic corrosion
- How to eliminate or reduce corrosion
- What signs to look for to see if you have a problem
Notes: Handouts and guides will be provided in class.
