Marine Battery Storage Tips from A Pro Angler

Battery Care from BASS Master Edwin Evers

June 6, 2017

“Electronics are getting bigger and bigger and bigger,” states 2016 Bassmaster Classic winner, Edwin Evers. “Color screens draw more power than before.” Additionally, Evers notes that aboard a tournament level boat, it is a must to use marine accessories like power poles, livewell cooling systems, plus circulating and fill pumps and a jack plate for the outboard engine.

“Small cranking batteries will not serve,” says this pro. Practicing what he preaches, Evers’ Nitro Z21 is fitted with a bank of TKK batteries

Even though the Optima Blue Top AGM batteries Evers uses are among the finest available,( he claims to have a pair in one boat for 8 years that are still going strong as of this writing) he takes the following steps to make sure they perform their best and last their longest.


Off Season Storage
I recommend completely charging your batteries before storing your boat, then disconnecting the terminals so nothing can draw the battery down. It is also critical to have a battery maintainer/charger hooked up through the off-season to continually maintain your batteries; I use the OPTIMA Digital 400. When the seasons starts, you’ll want all your equipment ready and in top notch form; if your batteries are at a full charge, they will be ready to perform and you’ll be ready to hit the water.

Coming Out Of Storage
Check all the connections for tightness and corrosion. A loose connection may prevent a battery from receiving a full charge or delivering current, which is not good because it can negatively affect the performance of the battery. If you have a built-in charger on your boat, be sure there is no corrosion in the terminals; I see this a lot. Buying a can of battery cleaner/protector can help if you have this issue. Be sure your batteries are charging evenly (each battery should be charging at the same volts), which will help maximize performance.

I prefer to use a heavy-duty 12-gauge extension cord when storing and charging my batteries –and I always use the shortest cord possible. Also, do not let your batteries sit for an extended amount of time in a state of discharge – always charge them as soon as possible.


The right charger, like the OPTIMA Digital 400 and Digital 1200 Performance Maintainer and Battery Chargers I uses, will enhance the performance of 12-volt AGM batteries. The Digital 400 Maintainer maximizes battery life, recovers deeply discharged batteries and keeps 12-volt AGM and flooded batteries healthy during storage. The Digital 1200 can charge, condition and maintain as well as recover deeply discharged batteries.
