A slow gradual decline (normal aging) in battery performance can be due to sulfation on the plates rendering them less and less efficient over time. A sudden catastrophic failure (among other things) can be due to an internal short such as accumulation in the bottom getting so deep it creates a short across the cells, or perhaps severe vibration can result in plate failure. A new battery can have a rating of X number of "Life Cycles" being roughly how many times its discharged then recharged, so the more its kept at or near 100% SOC the better. I'm my RV I don't like to discharge my house batteries much over 20% to 30% down.

Hope this helps , there's MUCH more but that's good enough for now I hope. I'm sure the other fine gents can add to this.

Today's Featured Article - Third Brush Generators - by Chris Pratt. While I love straightening sheet metal, cleaning, and painting old tractors, I use every excuse to avoid working on the on the electrics. I find the whole process sheer mystery. I have picked up and attempted to read every auto and farm electrics book with no improvement in the situation. They all seem to start with a chapter entitled "Theory of Electricity". After a few paragraphs I usually close the book and go back to banging out dents. A good friend and I were recently discussing our tractor electrical systems when he stated "I figure it all comes back to applying Ohms Law". At this point ... [Read Article]
