Thanks for that Karl.

Recently, I mistakenly drained this new 100 Ah battery down to 11.xx
Volts then used this 7 Amp charger to bring it back up. The charger
showed it as charged and didn't display a fault but I should try
depleting the battery a little then charging it with my older
"intelligent" higher Amp charger.
