I'd second the notion on battery replacement, but if you want to see if the battery can still hold a charge, do it slowly.....with a battery tender or other such device.
Battery tenders are relatively cheap ($50) and can be hooked up without even opening the hood (once you get good at it).
I have one of these Schumachers and you just connect the plug in adapter to the positive battery cable lead under the hood on the drivers side and ground it to a screw that sits just below in the chassis. You can connect and disconnect it in seconds without even opening the hood. The plug-in cable is the perfect size so you don't have any excess flopping around when you're driving. Just put the clips aside because you don't have to use them. It monitors the charging to prevent overcharging and has status lights so you know what's going on.

The battery tender sold at Parts Rack has 2 cables that are detachable. One is a cable with 2 clamps on it for direct connect to battery terminals, the other is a cable with 2 0 ring attachments. Basically you run the one O ring to the ground and the other to the post under the hood. Run the connecting wire down by the ECU so you have a place to tuck it away during normal driving and you have an easy way to hook up to a tender without opening the hood. Been doing this for 2 years now.
I see..... any pictures?
Today no, tomorrow yes. I am on duty so I cant take photos for you.

Does anyone have a picture diagram to show where to connect under the hood for 2010?

+1. Cigarette lighter socket is the simplest. Window gets rolled down 1/2" to let the wire through.[/b]
Even better, mine plugs into the cigar socket
