I have to store my boat off site. can I keep all (3) batteries charged w/ this? Will it stop charging when batt. full

I dont see why not if your batteries are all looped together. i only use on one battery at a time with my pop up, and as long as its a partially sunny day i dont even need another battery. Keeps it topped off even with the usage from a family of 4 camping. works great.

I charge 2 6v lead-acid batteries (in series) with it for RV - have had no trouble. This link gives the various charge rates and protections. Not sure how the controller would handle 1 bad battery of 3 wired parallel.http://www.directdepot.net/manuals/Go_Power_MAN_GP-PSK_80.pdf

This is a battery maintainer, your batt. should be charged before you use this.

Not sure the on board charge in my boat will turn on and off when battery need charged. The charger on the pump is the same amperage but not positive that the charger is of the quality as DUAL PRO charger in my rig. Everything looks lit it should work but to be safe, I would try to contact customer support.

Yes. I separated my batteries for one to crank the motor and one to run house accessories. When the motor starts, the cranking battery gets charged first, then when 13.2 volts or so are reached the relay turns on and charges the house battery. At this point both batteries are being charged at the same time. My boat has a 70amp alt on it and the system works great. Pain to install but well worth it. Hope this helps. ~ Robert

I would think it would charge it no problem. I would leave it in maintenance mode or automatic mode, to prevent damage to the battery .. the chargers do a good job deciding what mode works best depending on the battery voltage. I have mine running to marine 12 volts and two 6 volts hooked in series. When they are pretty much drained it will take around an hour to bring them back. What i like is if I'm using a lot of power it will adjust its output automatically..

I would think so Alan, but maybe ought to call Battery Tender. I leave my two boats plugged in for months at a time, and when I'm ready...they're ready...at least the batteries are!

With these type batteries, you will want to use them until they are fully dead before charging to get the most out of them. I would not store it on the charger it self. Any other way will be fine.

Yes, I keep them hooked up to 3 batteries that power my trolling motor on my boat. They do a wonderful job and while sloppier, have lasted much better than those "boat" battery charging units that coast enough to buy ten of these. I keep three of these hooked up all the time.

You will need to put the battery in some sort of case to be safe. The battery will short circuit if accidentally submerged. It could also suffer damage if left loose inside the hull. I use this in my Ocean kayak trident 13. This kayak comes with a mouted battery bag for the mentioned reasons. You may e able to buy the bag and mount it in your kayak.

Yes works well keeps Batts charged and then floats best unit I have found and have tried many.

Repoleved pretty much answered the question. It depends on how much you use the battery and how much you drain down the charge. Mine runs a circulation pump for my solar water heater. I have a 12 boat (deep cycle) and it always seems to keep it charged up. When my panel arrived it had a cold solder joint and I had to re solder it to make a good connection, and you need to figure out how to mount it.

I use this product to recharge batteries and maintain full charge after returning to my dock. I hope this helps.Roger

Yes you can but not advised. It will go down to a trickle charge when batteries are fully charged. ok

yes that is what I do in my boat for 2 rv batteries and it works great. make sure and get the power regulator so you don't over charge your batteries.

I installed mine on top of a party boat outboard and it seems to do a good job of keeping the battery charged year round. It needs better terminal clamps or replace them with crimped on fittings though. It is just a trickle charger though.

I use mine in my boat to run a acquarium aireator to keep bait alive. lasts several days before the battery needs charging.
