A marine battery, however well maintained, will eventually run its course of life. When that time comes, how will you recognize the signs for replacement?
Here are some tell-tale indicators to look out for during the battery’s lifespan that point to poor health:
Onboard Accessories Start Operating Slowly
This may include a lot of today’s technologically advanced onboard accessories such as the radio, navigation system and cabin lights.
The Battery has Difficulty Holding a Charge
For example, if you recharge your battery and notice it’s depleting rapidly, and the battery is unable to hold a steady charge.
The Battery Loses Voltage Quickly After Recharge
Although it varies between battery chemistries and size, when a battery is fully charged it should have a voltage between 12-13.
The Battery Has Shorter Run Times on the Water
For example, if your boat begins to perform unusually and/or you notice your onboard accessories not working or slowing down.
The Battery is Leaking or Cracked
Your battery can unexpectedly crack or start to leak for a variety of reasons including physical trauma, overcharging, acid build-up or extreme shock and vibration caused by rough terrain out on the water.
The Battery’s Terminals are Corroding
Over time, corrosion on battery terminals can cause sulfation or a build-up of sulfate crystals, which will drain the battery’s life.
The Boat Feels Slow-Moving While Accelerating
If a battery is in good condition and fully charged, the boat should be able to accelerate immediately upon ignition.
The Engine Won’t Turn Over
If it takes more than a couple of seconds for the engine to do its job, there may be an issue with the battery.
