Several changes have been made in battery parts. The terminal posts have been shortened and the height of the flange or neck in the cell covers has been slightly cut down.
As the old style parts will not be held for service, it will accordingly be necessary when installing a new style group assembly in an old battery to either build up the new post to correspond with the height of the old one or cut off approximately 1/4” from the old style post to correspond with the height of the new design short post. It will also be necessary to file down the shoulder at the point shown in Fig. 807, so that the cell cover will slip down into the correct position.
When it is necessary to install a new post or cell cover on an old battery, it will be necessary to slightly bend the cell connector as shown in Fig. 808 due to the difference in the height of the new and old style parts.
