what happens when the boat gets full of water? Is it possible to overcharge the battery?

the battery does not get affected if the boat fills uyp with water (which rarely happens- only if it overturns), just take it out of the water-

I'm not a battery expert, but you should really stick to the charging voltage and initial current they show on the battery. Overcurrent will certainly warm it up and it may leak or explode on you, or just shorten it's life.

The charge port has a flip on cover so if you go in puddles it wouldn't get wet and the battery is a sealed lead acid. Shouldn't be a problem but I've never done that. Of course I live in Southern Cali - so there's been no opportunity to really ride in the rain here.

If you use any battery larger than the one included, don't use in water. The hull will split open where the tape holds it due to the larger size of the battery. Water will ruin your electronics.

I don't think this was designed for outside/boat conditions... they ask you to plug it into your cigarette lighter and place it on your dash... water would ruin it, hope this helps, Roosevelt C.

I use my solar charger in a boat to keep the automatic bilge running. The only thing I can comment upon is low light. I do know that the charger is not sufficient to keep my boat batteries charged if I put the boat on a trailer and keep it in an unenclosed carport. The carport is open on both ends (North and South) and on the West side as well. Evidently not enough sun light gets in to sufficiently charge the boats batteries while the boat is parked in the carport. There are some shade trees around the carport also that may be contributing to the issue.

Yes, Mine gets wet by waves all the time. I also leave it on my yak in the rain. The fish-finder is in fact waterproof. The battery is fine if it gets wet as long as its not submerged for any extended time. I have accidental submerged the battery under with no adverse effect.

I think you would risk damaging the battery compartment if you did. If it stayed out of moisture and water it might be okay.

Not long eough. It's only 1200 mah. The boat leaks and the engine gets too hot.

Yes you can submerge it just make sure the everything is screwed in tight especially the battery compartment. Good Luck!

When switched to on and you start your boat your alternator will charge that starting battery. After three minutes the batteries will be combined by the ACR and your alternator will charge both batteries. When you shut off your engine the ACR will isolate your starting battery so it can not be discharged. So listen to that favorite song track for hours till the battery is dead if it's that good. There will not be any issues with 11 volts it treats both batteries the same as far as voltage charging is concerned. Start your boat and your good to go. I would suggest both batteries be in good condition. This product is an install and for get. Best money you will ever spend.

No, but you may be able to bury the unit if its kept in waterproof housing. Check out a boat battery protector

I do not recommend this boat.... The first one we bought the battery caught on fire. The second one we got in exchange lasted maybe 5 minutes on the battery. The seller recommends charging and using the battery to build up but we just got annoyed. Sorry we sent the second back too.

No. it would probably surge to high and would drain the battery in minutes. I tried to run my AC on my boat and it immediately dropped to 60% battery. You would probably have to string multiple batteries to it for that to work... Like 10 more.

I cannot answer that question. I think from all I have read about this charger it cannot overcharge or undercharge its built into the charger. I use mine to charge my boat trolling motor and when the green light comes on I always disconnect it. I have never left mine on to continually charge. Some battery chargers will damage the battery if they don't switch to the maintenance cycle. But once again I think this battery charger it's all built in to not overcharge. That's why I bought it. Hope this helps some. I am just telling you how I use mine and I have never left mine hooked up past the full charge. Sorry.

A couple of reasons danger of over charging the battery causing the acid in the battery to boil gases build which cause it to blow up or crack housing and leak second it will flop around unless permanently mounted

This is almost the exact application for which I am using my DROK voltage indicator. YES. A fully charged battery will read approx. 12.7 volts on your boat's wet cell battery. Different instruments/devices require different voltages, so there is no real point at which you can expect things to "stop working," but yes, the voltage will drop as the battery is drained down.
