I had a cell replaced by a mechanic, he charged me 350.00 and the car run fine for 1200miles then failed again. I learned from this mechanic on how to do the job myself so I bought a used cell and installed it my self. However, while doing the job, I noticed that the connectors to the batteries were corroded. I cleaned them all with vinegar reinstalled them and now I have 13000 miles on this job. I feel that battery corrosion plays a big role on battery failure. I will recommend battery preventative maintenance at 100k miles and that includes reconditioning if you can. But, just cleaning the terminals will expand the life of your battery life.
