OT: Charging boat batteries question 


I wouldn't ask this on here normally, but considering how dead this place is, I figure any post is a good post, right?

I have 2 batteries in my boat, a "starting battery" and a "deep cycle battery."  There is a Perko battery switch where you can use battery 1, batter 2, both, or "off".  I also have alternator problems.  Hopefully getting that fixed soon, but in the mean time I need to charge my batteries with a charger.   Can I charge both batteries at the same time by putting the charger on one of them and putting the switch on "all"?  Or do I need to charge one at a time with the switch on "off"?  Or some other combination?

Deep cycle (trolling motor) batteries should be charged on a trickle charge IMO.  You should be able to charge both, but I'd do it separate.  I usually charge the deep cycle battery overnight on a 2 amp.

My Nitro has 4.  The trolling motor is 24/36 volt select.  Those and the main battery are all connected to a charging bank that you should be able to pick up from BASS Pro etc.  You only have one plugin and it shows the status of each battery.

My advice to be extremely careful where and when you charge them.  I had a client take one of his out of his boat and set it up on a trickle charger inside a workshop area in his garage during the extreme heat last summer.  Evidently, the battery and charger overheated and a fire ensued doing $50,000 in damage.  Long story short: be careful.

Never owned a boat battery but most deep cycle batteries are nickle cad batteries others are lead acid. They are very different in how they should be charged. Deep cycle normally, if it is a Nicad, should first be totally discharged, then recharged as they "remember the low setting and hang up there" and lead acid cells should never be fully discharged. 

I worked on airplanes, not boats so they all may be lead acid on boats.  But if you hook them up in parallel, the charger does not have more current, but less for each battery.

And I would add IMO the time saved is not worth the danger to having a fault occur.

Having just retired from Ranger boats after 27 years I know several people who are experts on that sort of thing  if you need names let me know.

Could have been but that is why I am encouraging him to be extremely careful.

That is another characteristic of NiCad batteries, they are prone to "Thermal Runaway" if not treated properly and that can and does often lead to an explosion.

It is not that often these days that I read an entire thread in Hawg Lounge and come away feeling more intelligent.  I'm not sure  what GregHog decided to do, but I bet he feels more confident about it.  There was not a pointless post in the thread, at least until now. eek

Well, because you brought the thread back up ... since he mentioned the possibility of flipping the switch to "All", have we ever heard from GregHog again?

I recharge my batteries with saw palmetto.  I wonder if that works on boats? noidea

I am alive biggrin  But having lots and lots of "fun" with my boat.  

I love having a boat, I really do, but I was warned in advance that a boat is "a hole in the water in which you throw money" and that is correct.  Haven't gotten to take the boat out in about a month due to issues with alternator and batteries.  Still trying to get them resolved.  We will see.
