Alkaline AA batteries are rated 1.5 volts, while NiMH AA batteries are rated at 1.2 volts. NiMH generally refers to a battery being rechargeable and to the materials from which the battery is constructed.
When converting from 12 volt batteries to 6 volt batteries you need to be sure that you connect two 6 volt batteries in series in order to continue to provide 12 volts to your electrical system. Remember that batteries in series compound their voltage, but not amperage.ost rigs that have 2 or more 12 volt batteries have them wired in parallel. When going to the 6 volt batteries, you must wire pairs of them in series to produce the needed 12 volts. This is actually simpler than it sounds.... see the diagrams below.
