No issues with changing a battttttery.

You might have to reset the clock on your radio.

 

Just as Doc Olds said. You shouldn't have any problems. Just be sure not to touch the Pos. and Neg. cables together. I'm not sure about the H3, but on some vehicles it can cause the computer to short out. I doubt that would happen on the H3, but doesn't hurt to be careful.

 

I had my battery disconnected for 5 days while I replaced the heater core. Just had to reset the clock. Radio still had preset stations.
