Replace Different Car Battery

Replace Original Car Battery With A Different One

Welcome to http://CarTrek.com

I usually go by the book when replacing car parts. But recently I replaced a car battery with a different size. I decided it is OK, except you need to pay attention about:

1. which side are the two terminals on?

2. Is positive closer to the left or right?

3. is the cable too short?

4. what about enclosures?
