How long do you run your batteries?
I have the twin Trojan 6 volt batteries in my TT. I bought them in the Spring of 2010. That makes them 6 years old starting a 7th season. Would you trust them? I don't camp in places where it is e...

That's what we do with our older batteries. My batteries are not Trojans but are the standard issue cheap GP24 12VDC Interstate batteries the dealers provide in most RV trailers.
I know from experience what performance to expect on how long these batteries produce 12VDC power over the extended time before they get down to their 50% charge state when camping off the grid. When this starts falling back I will start more dedicated charging routines...
If you take care of the batteries they will last a long time... When camping off grid I monitor my batteries all the time with my meter panels and physical inspections looking for over heating of the battery cases and boiling out of fluids etc...
I installed mine in late 2008...
When camping off the power grid my batteries are being used 24/7 with a three hour daily charge period starting when they drop back to their 50% charge state. The three hours charging routine brings them back up to their 90% charge state where I can expect a good 99% of the performance capacity once again. By experience I can do a good 12-14 cycles of this 50% to 90% charge states before having to do a 100% charge state which in my case takes a good 12 hours or more of smart mode charging. Keeping within these guideline I don't seem to be doing much harm to my batteries...
