Minn Kota MK440PC 4 Bank x 10 Amp Precision Charger 
Precision On-Board Charger
Longer run times. Shorter charge times. That's the precision difference that makes these the best chargers on the water. You get the fastest charge, hands down. You also get a smart, precise charge that protects your battery, extends its life and creates longer run times. So you can get out there quicker, and stay out there longer.
The Precision Difference
It compensates for overloaded power outlets. It pumps out up to the full 10 amps of power. It cleans and conditions your battery each time you use it*. It lets you choose what type of battery you have to ensure a perfect charge. You want to know what makes a Precision charger different? Where would you like us to start?

We build 'em like we build everything: to last. Rugged, fully corrosion-resistant design. And all of our Precision chargers are backed by our three-year full replacement warranty.
The science is simple: digital is better. Our microprocessor-based design delivers a faster, more precise charge every time. And a longer day of worry-free fishing for you.
THE FASTEST CHARGE
Some chargers don't put out the amps they say they do. Ours do. Every single time.
Low-Line Voltage Compensation
When outlets get overloaded or hooked up to long extension cords, they don't put out the 120 volts they're supposed to. That makes charge times go up. Unless you've got a Precision charger, which compensates to deliver a fast, consistentcharge no matter what.
AC Plug Holder
Keeps plug dry, safe and easily accessible. Included with all Precision and Digital chargers
Automatic Temperature Compensation
Charging your batteries at higher or lower temperatures can damage your battery. Our Precision chargers sense and adjust to temperature fluctuations to ensure a fast, accurate charge.
Automatic Multi-Stage Charging
Automatic Multi-Stage Charging controls the voltage and current your battery gets throughout the charging cycle, ensuring a fast, safe and precise charge.
