Car hit in rear; very little visible damage; should I have batteries checked?

Well, my precious 2008 Prius was hit in the rear by an uninsured driver yesterday. I was sitting at a red light, looking at the traffic light, waiting for it to change, when “Blam!†this older Nissan Sentra runs into the back of me. I was shook up, but fortunately there seems to be only superficial scratches on the back of my car. The car was from California and had a license plate frame on the front of his car and that’s what scratched the back of my car. I have a $1000 deductible, so no way I’m going to file a claim. The police did come and make a report. The other guy’s car was towed because he had no insurance. My question is should I have my car checked out by the Toyota dealer? Could any damage have been done to the batteries from a fairly small impact? I’m thinking it would be unlikely, but I don’t want to fail to have everything checked out. What does everyone think? Thanks.

 

Thank you for the responses. I had the car checked out by the Toyota dealership where I bought my last couple of Toyotas and where I have had them serviced for years. They reported no damage to the bumper. It really was a "slow speed" collision that fortunately didn't deploy the air bags. It was enough to really shake me up but fortunately appears to have done no more damage than a small dent (1/2 inch wide) and a scratch (1/2 inch long). Yes, I do have the uninsured driver's insurance. Since the incident, I have taken to giving the driver behind me the "evil eye" when they are approaching me at a red light, and so far it seems to have kept them at a respectful distance in back of me most of the time. At least I feel like I'm doing something.
