I realize this sir. But I am sure that they could fix it back to good working condition. Taken from their FAQ section.
Service for old company "Arc" Products
Although Arc Flashlight LLC is out of business, Peter asked CIS to provide support for their old customers as a way to encourage them to patronize the new company. This is done at CIS's expense. Although CIS does not have any of the older products (or parts for them), it will offer a store credit for all the old company's products. This includes the Arc-LS, Arc4, Arc-AA, etc. To find out what this store credit is, please email us. For old Arc-AAA's, since we are making a new version, we can repair/replace the old version. But for all the other flashlight designs, we offer just a store credit. We hope you will give CIS and the new Arc designs from Peter Gransee an opportunity to win your business.
