Re: [Electric Boats] Re: Deep cycle info and charging requirements

Dan:

Also keep in mind the charger you will be using. Because the different types batteries (flooded, AGM, Gel) you are learning about like different charge profiles and voltages you need to be careful you use the right charger for the batteries you choose to use. Some chargers have switch settings others are just made for just one type of battery. Others are programed with a plug in card. Be careful otherwise you will be killing batteries and spend more $$$$ than you need to. I have AGM batteries for my 48 volt propulsion bank. The two chargers I use on that bank are set up to charge AGM batteies ONLY! I am using Gels for my 12 volt house bank. Why? Because I already had a fairly new charger installed on board that had a switch setting for GEL batteries thats why. In short the type of batteries you are using must match the chargers.

Well reading the second one, one needs to read between the lines to get a full picture. My take on it is they are getting you to recharge as fast as possible to make sure you HAVE a full charge. Best bang for the buck so to speak. While they did not say that it was best for the battery they mentioned it doesn't hurt it up to a certain charge point. Leaving the battery in a sate of discharge for extended period of charge was to mean over winter not over night or one or two nights. Equalization seemed to be a big factor in prolonging the life of a battery.

I will have to bone up on my batteries though. I thought a GEL and AGM were the same thing. More research! I think I may look into a floating lab for my Triton. Try different things and report in on them. It will give me something to do while I am sitting with no wind, sun, or Battery.

Here's a link to some good info about deep cycle batteries in general:

And here's a decent primer about lead acid charging requirements:
