As most of you know, a dead battery in the L170 and similar models prevents starting the engine, which prevents lifting the bucket, which is required to access the battery. Thus a crane is needed to lift the bucket in order to replace the battery. So we just built a high amperage cable assembly that connects to the battery and extends upwards to a positive/negative terminal that can be used to jump the machine with the boom down. It bolts to existing fixtures and also has a trickle charge feature for winter. Am thinking of producing a kit and selling it if anybody is interested. A dead battery should not involve a crane.
