Onboard the Menemsha I have theree batteries I need to maintain a charge on: two deep-cell and one cranking battery. I [may] install a Minn Kota three-bank, five-ampere per bank, Model 315 charger to maintain and recharge these batteries while the boat is on the trailer at the boat storage yard. Any experience or advice with [the Minkota 315 charger]? Any alternatives in the [$180] price range? -k

About a year ago, or perhaps even longer, I bought a three-battery charger with five-ampere per battery output from BASS PRO SHOPS for the purpose of maintaining a floating charge on three 12-volt AGM 75-Ampere-hour batteries. The charger was selling for about $150.

Compare at:

This charger has been in constant operation, 24-hours a day, seven days a week, for over a year. It has maintained the battery charge very well. Occasionally we use one of the batteries and discharge it. When done, we return it to the charger and restore the charge.

Having an onboard battery charger is a good investment for a trailer boat which will have a lot of down time. You can plug the battery charger in prior to using the boat and allow it to refresh the charge on all the batteries. When you get to the water, the batteries will be ready to go.

Jim, did you install the battery charger on your boat? If so, could you elaborate on the installation?

I have a battery charger on my boat, but not the triple battery model I mentioned above. I have a similar two-bank charger. It is connected directly to the two batteries on my boat. To use the charger I just plug its AC cord into an extension cord, and plug the extension cord into an AC outlet.

My typical utilization of the charger is to top off the boat batteries before heading to the launch ramp. If we will be using the boat, I usually pick it up from the storage yard the prior evening. I plug the charger in an let it refresh the batteries for several hours. The next day we drive off to the launch ramp, and I am confident I am starting the day with the batteries in full-charge condition.

When cruising, if we stay at a dock with AC power, I will plug the charger in. That way if we stay up late in the cabin with all the lights on, the batteries won't be carrying the load.

Thanks Jim. I was curious where on the boat your batteries are located and where is the battery charger located?

Newt ....

I installed a Guest two bank 2620A on my 210 Ventura three and a half years ago. The two batteries (AGM's) and the charger are located forward on the starboard side in the space under my helm.

Here are some pictures of the install.

As Jim mentioned, you can just plug into any 110 outlet to charge your batteries.

On my REVENGE 22 W-T Whaler Drive the batteries are in the original location, at the stern, one on port and one on starboard. The charger is mounted to the bulkhead of the rear deck, and it is under the stern deck. If you lift the port hatch you can see the charger and its LED indicators which show the status of the charger and the state of the battery charge. The power cord is just left loose. I fish it out when I need it and plug it in.

I have purchased and installed the 3-bank Minn Kota onboard battery charger, I liked the idea of a waterproof, saltwater resistant, and vibration/shock resistant charger.
I was having a hard time finding a good place to install the charger due to its size and weight. The charger is approximately 12" long by 7" wide, and 4"+ deep. The onboard charger weighs approximately 12-14 lbs.
I have an isolated deep cell trolling motor battery installed where the marine head used to be and heavy gauge wires run behind the starboard teak gunnel panel with trolling motor connecting terminals on the starboard side aft of the fishbox. The chargers size, in conjuntion with being able to run the charging wires to all three batteries, necessitated placing the charger somewhere on the seat/fishbox component.

I have had it installed for over a week now, and it reads that all the onboard batteries are at full charge. Thanks for the input guys-will let you know how it performs!-k
