ED,
I have a link to the testing page below.
You can buy one at the local parts store, but nowdays, most people just take there batteries in for checking. I know Kragen does checking for free.
Check it out. Given the right conditions, they can and will explode.
I accidently used the battery as a tool tray and a long screwdriver touched the posts. It was glowing red hot within seconds and it sure got my attention when I grabed it.
Best Wishes
Lonnie
