Repairing Eveready Batteries
To properly open and re-assemble an Eveready battery, proceed as follows:
1. Take a hot putty knife and cut the compound from the top of each of the inter-cell connectors until the entire top of the connector is exposed.
2. Center punch tops of cell connectors and terminal posts.
3. Drill off cell connectors. In drilling off crescent cell connector use 1/2 inch drill, and for heavy type connector use 5/8 inch drill.
Drill deep enough, usually 3/8 to 1/2 inch, until a seam between connector and post is visible around lower edge of hole. Having drilled holes in both ends of connector, heat connector with soft flame until compound adhering to it becomes soft. Then take a 1/2 inch or 5/8 inch round iron or bolt, depending on connector to be removed, insert in one of the holes, and pry connector off with a side to side motion, being careful not to carry this motion so far as to jam connector into top of jar.
4. After connectors have been removed, steam and open the battery, as described on pages 332 to 335.
5. Examine plates, and handle them as described on pages 335 to 355. Remember, however, that Eveready plates which show the presence of large amounts of sulphate, even to the extent of being entirely covered with white sulphate, should not be discarded. A battery with such plates should be charged at the normal rate, and given a 50 percent overcharge.
6. Before re-assembling plate groups preparatory to assembling the battery, take negative and positive plate groups and build up the posts with the aid of a post builder to their original height.
Assemble groups in usual manner, taking care that posts on straps are in proper position relative to group in adjoining cell, so that cell connectors will span properly. Eveready batteries use a right and left hand strap for both positive and negatives, making it necessary to use only one length of cell connector.
