Time for new batteries.

Thanks for the replies. I don't have solar or a amp meter, but are seasoned campers and in 6 years only used the Honda A-2000 1 time to charge TC batteries. I keep a volt meter in truck all the time to keep an eye on batteries. We go out for 2-4 wks. and usually move around a lot 3-4 days, and the truck does a good job of keeping batteries charged. I needed to rotate my tires and change oil and not wanting to remove the TC went to my guy (easier), while there I had him load test the batteries and said their testing like new to almost new. I couldn't believe for 6 year old batteries that he said that. Guess he doesn't need the $$. This is why he's our guy , he doesn't rip people off. I will be looking at all options a little harder now that we got good news. The Lithium's sound absolutely fantastic, but really put a dent in the ol' wallet. Hopefully as tech. goes Lithium will get cheaper and make them a better choice. Thanks again.
