As I remember it, the writer said that if I start out on a trip with a fully charged battery (as mine will be having been tended by the Battery Tender Plus), that I will actually lose charge as I drive and that I will arrive with only 70% charge. That would not be good at all.
1. Does that seem correct?
2. If so, should I disconnect the charging wire (or put a switch on it to keep it off when not needed)?
3. Also, if so, is there something I can do to use the tow vehicle's power to keep the TD's battery topped off correctly

Yes, a true 'gas gauge' for your battery is a lot harder to do - It takes lots of electronics and computer power to do it, but they do make such a thing, if you're really interestedmrchuc wrote:The advantage of gasoline over electricity, of course, is that you can easily see how much gas is left by glancing at the gas gauge. Knowing how much electricity is left in the battery (and how much of that is safe to use without hurting your battery) seems like a lot harder question to answer
Wow! I am glad to know there is such a thing. Kind of restores my faith in electrical science. I was beginning to think that lead-acid batteries were magic.It does lots of other neat things too. It's easy to install and program, even for a novice. I've installed probably 25 of these on sailboats and had a more elaborate version on my own boat for several years and can heartily recommend them. If knowing where you stand on the 'battery gauge' is important to you, this is a 'must have'
