Battery charging

[Guest]

If I have two batteries connected in-line for a 12volt system do I need to disconnect them and charge each battery separately?

Also, I've been looking around the Internet and have not been able to find much good information batteries installation and maintenance. if anyone knows of a good site I would appreciate the help.

Thanks

I've been running with 2 batterys for about 10 years now. I have 2 12 volt start/deep-cycle batteries wired in parallel. (That gives you 12 volts with twice the amps, series gives you 24 volts, with the same amps)
I just hook my charger to either of the batteries, to charge them both, but as you probably know, it takes twice as long to charge them. The charger I use automatically shuts it self off when the batteries are fully charged, to avoid over charging, and wrecking the batteries. If you keep them hooked up all the time (winter, and summer), I find a set of batteries last alot of years.

Here's a pretty good site for battery info;
