Charging a 24 volt system?

[brownies]

I'm using just a small 12 volt battery charger. Same as I'd use to slowly charge any 12 volt battery.<br /> I have two batteries connected together for 24 volts for trolling motor.<br /> IF charger is connected to +/- on ONE of these batteries will it charge just that battery, or both?<br /> Should I disconnect these from each other for charging?<br /> AND/OR....Also have on onboard mounted charger that has four wires designed to charge two 12v batteries at once (appears to be about the same as having two 12volt battery chargers, just compact, and convenient)..<br />...The effect of connecting these four wires to BOTH batteries while they are connected to each other as 24v?<br /> I may be thinking into this too much, but, I get about half way through the thought process and blow a brain fuse each time. <br /> Is there somebody that can explain this to where even an idiot like me can understand?

Re: Charging a 24 volt system?

Yes, if you hook the battery charger to just ONE of your 12V batteries, then you would only charge that one battery.<br /><br />As for the second battery charger with two sets of leads, it really depends on the design of the charger. It is certainly possible to design a battery charger that could do that, but I can't tell you for certain if your particular charger can do it. Most likely I would say yes, you could hook it up in series and charge your entire 24V system, but if I am wrong, it won't just "not work", it will completely destroy your battery charger. You may not want to risk it.
