All my batteries are made in the US. Exide is not anything better.
Re-read what I stated, start and run time has never made any difference on battery life across the past 13 years. My charging system works perfectly, and always has. 12.1 to 12.5 volts measured directly from the battery is perfectly normal...and fully charged on an older battery.
It’s when it drops below 12 volts that you know it’s failing.
