Hi, I am A. Stevens here to help with your question!
Based on the model you provided, I wouldn't suggest trying to repair the unit.
It may not be worth your effort/money/time.
Unfortunately the product is discontinued...perhaps we could find one on ebay similar or comparable that would use the same accesories.
This model uses miniDV tapes...which you could find another model camera that would be able to use it.
As far as the batteries go though, I doubt it.
Here's a model that uses miniDV tapes: http://www.amazon.co.uk/Canon-MV630i-Camcorder-Kpix-optical/dp/B0000E3HAK/ref=lp_15346061_1_21?s=photo&ie=UTF8&qid=1415732951&sr=1-21
And another: http://www.amazon.co.uk/Samsung-VP-D371W-Camcorder-Optical-Digital/dp/B000ODTNYC/ref=lp_15346061_1_22?s=photo&ie=UTF8&qid=1415732951&sr=1-22
I wasn't able to locate your specific Panasonic model for sale though unfortunately.
