I've got this Zeikos battery for my new camera and a Vivitar universal charger. The 2 contact points on the charger can be moved to align with the contact points on the battery. The battery has 4 contacts points and the label on the battery which doesn't align exactly enough to tell me which of the two I should use. Here's a link to the battery: http://zeikos.com/copy/catalog/product_info.php?products_id=375&osCsid=28c9f97de46f185af4247568da99d9d6 Can you tell me which are the two contact points? BTW, the interior of the camera has 4 contact points.
