The rate of internal failures I see in marine batteries is highest in 4D & 8D then group 24, 27 & 31 flooded batteries. Will a battery still work beyond this point? Absolutely, and they do, but the catastrophic failure rate, such as an internal short, starts to increases pretty steeply as the rated Ah capacity drops below this 80% figure. By industry standards a flooded battery is dead when it can no longer deliver 80% of its rated Ah capacity. The AGM range has very low internal resistance making them particularly suitable for high. In the real world we have so many factors that inhibit lab like results that it is nearly impossible to get anywhere close to this data.
