Battery Swapping Between Vehicles?

Since you didn't tell us which battery was used, we cannot provide a good answer. Now that you are not in such a hurry go out and solve this problem.

As long as they're both 12v, and you don't damage the connectors in your hurry, then no.

Oh, no!

Battery swapping like this is the leading cause of car trouble.

What ever troubles the Jeep has, the Eclipse now has. The contagions of many car problems lay silent in the battery, waiting for just the opportunity you have given them. The jump start is the usual method, but a battery swap...

On second thought, you should be fine.

Oh Dear! You forgot that whatever problems the Mitsubishi had, are now transferred to the Jeep too! I suspect the vehicles will be fine, me,,,,,,,, I'm not so sure. Have a great day guys.

you might loose the memory on your radio, and also possibly some information on the engine management, but the ecu will learn the data again.

the radio code can be difficult if you dont have it written down somwhere.

other wise there is no problem apart from the capacity of the battery

If the battery mounting/retaining facilities are not compatible, the improperly secured battery could tip over causing a fire and loss of the vehicle and occupants. Is that serious enough for you?

If the resulting fire happened in the wrong place, such as in busy rush hour traffic, on an express way, other people could be injured or killed also. If the fire started or propagated to a forested area, the resulting fire could start a forest fire, burn millions of acres and cause the loss of uncounted woodland homes and their occupants.

But if nothing like that happened, the most likely result is loss of radio programming and having to reset the clock.

Have FUN!

Sounds a bit far-fetched and over-dramatic to me. Auto batteries are not that different in size (unless you're stupid enough to try fitting a 6v motorbike battery), so they will either not fit into the space, or if they do they will not tip over. Besides, the electrolyte will not flood out, and it is more corrosive than explosive.

Battery capacity could be a problem if it is too small, then you might have trouble starting, especially if it doesn't start first time, but it won't cause any damage (unless you resort to a 'Basil Fawlty' when the car doesn't start). Too much capacity is not a problem, the car only takes what it needs, again no damage.

Radio codes are a pain!

Thanks for your input. Goes to show the people at the auto parts stores don't know what they're talking about.

they just want to sell you batteries.
