Here is my issue. If I drive for an hour, the battery reads 12.34 volts when I stop. Shorter driving around town gives lower voltage readings. If I put my Battery Tender on the battery and charge it until it says maintaining charge, it reads 12.84 volts after disconnecting the Battery Tender for 24 hours. If I put my Shumacher charger on the battery, it shuts off after one hour at 6 amps as fully charged. If I immediately follow with the Battery Tender it says charging and takes 24+ hours to reach the maintaining charge. I think the battery is bad and can't take a high amp charge, but will accept a low 1.25 amp charge to be fully charged. What are your thoughts?
