electrical info for dummies

I realize that my ignorance slip is showing,but a reply would be appreciated.
The context for the question concerns replacing batteries (Grp27) with T105s and managing the risk of a battery failure while on a trip.
The question... If a T105 failed and a replacement was not available but a 12V battery was -- what are the implications and hazards of temporarily becoming an 18V system until I get home?

Just take the other T105 out and use only the group 27.

Brian.

Sometimes a reason is not necessary.

Remember when you were a kid? When you asked "why" your parents would say, "because we said so." Hmmmmmm.

I remember hearing it to this day.

But, modern generation parents don't say that any more.

"NOT."

Ohm's law is voltage =current x resistance (E=IR). The resistance of the circuits will remain the same, but you are increasing voltage by 50%, so you will increase current by 50%. Most of your wiring, lights, brakes, etc. will not take the increase. You also have a huge mismatch in battery cells which will probably destroy both of them.
