Discussion: The Best Battery Chargers to use

I was trying to decide how I would present this information to all of you, and I realized that Steven Harris of Solar1234.com and of Battery1234.com did a terrific job on the audio presented on his websites, so I decided to use his information (and hopefully he doesn’t mind) on most of this topic, with some more detail added by me to unnecessarily expound on the wonderful information that he has provided.  If you decide to purchase ANYTHING that I have discussed today, please go to Steven’s websites and purchase from him through HIS affiliate links, to thank him for all of his hard work.
