MARINE BATTERY CHARGER BUYING GUIDE

LET'S FIND THE RIGHT WAY TO POWER EVERYTHING ON YOUR BOAT.

 

FINDING THE RIGHT CHARGER IS AS EASY AS 1-2-3

STEP 1 - HOW MANY BANKS DO YOU NEED IN A MARINE BATTERY CHARGER?

This simply depends on how many batteries you need to charge. You need one bank for each battery (include your starting battery, if appropriate).

STEP 2 - HOW MUCH POWER DO YOU NEED?

Our chargers have different levels of power in their charging banks. How much you need depends on how quickly you want your batteries to charge — or “recovery time.”

STEP 3 - SELECT THE TYPE OF MARINE BATTERY CHARGER YOU NEED

Pick the charger that works best for your boat from the types below.

ON-BOARD CHARGERS

PRECISION CHARGERS

The premiere on-board charger in fishing: it charges you up faster than anything else, and protects your batteries for years to come.

DIGITAL CONTROL CHARGERS

Designed similarly to our Precision chargers — with just a little less power — these chargers also protect your battery for years of worry-free fishing.

ALTERNATOR CHARGERS

Add an Alternator charger to your on-board unit for an extra boost and better battery life. These chargers take your alternator’s excess power and redistribute it to your trolling batteries.

PORTABLE CHARGERS

Digitally controlled for a fast, precise charge — and fortified with Automatic Temperature Compensation — that lets you take the action right to your boat.
