My car sometimes won't start..?

[mommy to a princess]

But when I shake the battery really hard it will...WTH is going on. I'm getting it looked at Saturday but in the meantime wondering what it might be?
THANKS!

My husband said sound like to him you might have a loose battery cable, so it should be tighten.

you might try cleaning the battery terminals and make sure they are tight. save your money and do it yourself. it,s not hard to do or have your neighbor do it for you.
