I had a Dual Pro Professional in my last boat for 7 years and it worked great. It charged 3 old batteries that it never should have charged for 7 years. They were odd batteries. One was an old battery from Comcast, one was an new battery that sat on the concrete floor of my father's pole barn for years, and the third I don't know where it came from. Out of those 3 batteries, two were from the previous boat owner and the third was from me. That Dual Pro kept them working for 7 years though, I never had to replace batteries in that boat. Ranger also puts these chargers in their boats which is a confidence booster. 

 

Also, I think the Dual Pro has 15 amps per bank which would charge the batteries faster than the others which are 10 amp per bank, no?

 

My current boat has a cheaper Minn Kota charger. Not the higher end Precision charger that has the equalize cell feature. I have 2 batteries that are 4 years old and most likely need replacing. However, if I could equalize them perhaps I could get another year out of them rather than replacing them which would be nice.

 

NOCO brand chargers are widely regarded on this forum as being compact and reliable. The Dual Pro's are fairly large, however they take space up vertically, so their footprint may actually be smaller than some of the other flatter chargers. 

 

I know that Dual Pro, NOCO, and Minn Kota are 3 of the biggest names out there in onboard charging but feel free to add others that I didn't add.

 

 

 

So out of these chargers which is:

 

1.)  Best

 

2.)  Best bang for your buck  

 

 

I'm not sure if the NOCO does but it would be nice if the NOCO and Dual Pro had the equalize cell feature that the cheaper Minn Kota does.

 

Also, if the Minn Kota Precision chargers can equalize cells why isn't this an option with the other more expensive brands?

I just bought the MK 315D, mostly due to the reviews. It’s my first onboard charger so I can’t rate it,,,,, yet. Lol

I know it’s a heavy bassturd,

Also, is 15 amps, 15 amps no matter what the manufacturer says about “Charges 2x times faster!”?

 

 

If two different brand chargers are 15 amps, will they both charge at the same rate?
