I use my coach often - generally every 2 weeks. My chassis batteries have never failed or even acted weak. I have a Liberty with on board engine battery charger and it stays powered up 99 percent of the time.- batteries should be optimally charged - right? Today I turned the key and nothing but red lights, the speedometer moved to 10 mph. Whats up with this? I retrieve my All Star Battery Tester (see Mangos prevoman.com tool list) and after unhooking the terminals on the batteries three out of four fail the test and indicate a dead cell in 3 out of 4 batteries. These batteries have been in the coach since 05, this is early 08. I found it odd that 3 out of four die in the same week? Can anyone shed light on this issue. The batteries were not dry or cooked or disfigured in any way. They were in need of water but not what I would consider dangerously low.

I might also add of that I have replaced more car batteries this year than I have in the previous 13 years. Is this a global warming thing?t
