$begingroup$ This rule of thumb is problematic as a 12V lead-acid battery is actually 6x2V cells in series. If a 2V cell of a particular size was able to be charged at, say 0.5A, six of them in series (six times the capacity) should also be charged at 0.5A. Voltage and power will need to be higher but the current should be identical.
