I have a Sonic Complete type 4717. Reply Ionic Admin 18 May 2017 Hi Eric, you could see if any friends/relatives/colleagues have a soldering iron and solder that you can borrow. Otherwise you can take the new battery and the toothbrush to your local TV repair shop or small appliance repair shop and pay them to replace it for you.
