Battery Management & Maintenance
Most boat owners understand the importance of maintaining your vessel and it’s propulsion system – however some do not fully understand the reasons behind or the importance of performing “annual service’.
Charging & Maintaining your Batteries:
We all know how important it is for us to regularly maintain our cars’ and truck’s engine, transmission, tires and brakes. The regimen of oil changes, tire rotations and brake checks every 3000- 5000 miles has been burned into our collective mindset since we were kids.
Understand the use of your Battery Switch:
Savvy boat owners have a similar mindset. They understand that without regular maintenance (annually or per 100 hours of operation, whichever comes first) their beloved vessel could end up letting them down in a much more unforgiving environment than on the side of the road.
Fuse Blocks & Circuit Breakers:
In southwest Florida our weather and water conditions create an environment conducive to fun in the sun but those same conditions can wreak havoc on a vessel’s propulsion and other systems thus increasing the importance of maintaining a regular maintenance schedule.
Your Engine’s Charging System:
When it comes to outboard maintenance with today’s technologically advanced motors one thing is for certain; seasons of neglect will lead to major repair expenses at the very least. The bottom line is that you should have your boat’s motors (Inboard, I/O or Outboard) and safety systems serviced at least annually by a certified technician. Don’t find yourself saying, “If I only would have…”

Power Maintenance at-a-glance
- Stay with one battery chemistry (flooded, gel or AGM) Each battery type requires specific charging voltages. Mixing battery types can result in under- or over-charging. This may mean replacing all batteries on board at the same time.
- Never mix old batteries with new ones in the same bank. While it seems like this would increase your overall capacity, old batteries tend to pull down the new ones to their deteriorated level.
- Regulate charge voltages based on battery temperature and acceptance (manually or with sensing) to maximize battery life and reduce charge time. Ensure that your charging system is capable of delivering sufficient amperage to charge battery banks efficiently. This generally means an alternator/charger with 25% to 40% as many amperes as the capacity of your entire battery bank.
- Keep batteries clean, cool and dry.
- Check terminal connectors regularly to avoid loss of conductivity.
- Add distilled water to flooded lead acid batteries when needed. Keep them charged. Leaving them in a discharged state for any length of time will damage them and lower their capacity.
- Clean corrosion with a paste of baking soda and water.
- Install & Use your battery switch. This will reduce accidental discharge ensuring the power you need will be available when required as well as allowing you the ability (in multi-battery installations) to choose a power source for house power needs while protecting your motor start reserves.
