The Ultimate Maintenance Schedule For Deep Cycle & Lithium Marine Batteries

Owning and operating Newport batteries enhances your boating experience, whether you’re fishing, cruising, or simply enjoying time on the water. To ensure that your equipment remains in top condition and delivers reliable, consistent power, it’s crucial to follow to a regular maintenance schedule. This guide covers the essential maintenance tasks to keep your gear top-notch.

Battery Maintenance

Monthly Tasks

Topping Off Charge

• Why: Keeping your battery charged prevents deep discharge cycles, which can shorten battery life or even worse, prevent your battery from taking a charge.

• How: To avoid issues associated with overcharging, use a battery charger that's compatible with your battery, according to the charging recommendations in your battery owner's manual. Some smart chargers are capable of reading your battery's chemistry and capacity, and can charge accordingly. It's important to top off your battery charge once a month to avoid deep discharge. 

Cleaning Terminals

• Why: Clean terminals ensure a good electrical connection and prevent power loss.
• How: Disconnect the battery and use a mixture of baking soda and water to clean the terminals. Use a fine wire brush or toothbrush to scrub off any corrosion.

Checking Terminal Tightness

• Why: Loose terminals can lead to poor connections and operational failures.
• How: After cleaning, ensure the terminals are dry and reattach them, making sure they are tightly secured.

 

Quarterly Tasks

1. Applying Anti-Corrosive Spray or Gel Treatment

• Why: Prevents corrosion build-up on battery terminals, enhancing longevity and performance.
• How: After cleaning and tightening the terminals, apply an anti-corrosive spray to protect against future corrosion. We like the CRC Dielectric Grease.

 

Conclusion

By following this maintenance schedule for your marine batteries, you can ensure optimal performance, extend the life of your equipment, and a trouble-free boating experience. Regular maintenance not only keeps your gear in top condition but also enhances safety and reliability on the water.
