Drill it about 3/4’s of the way through. A series of holes if the single center one doesn’t cut it. Then take a flat blade screw driver that’s bigger than the hole and start wiggling/prying it around to loosen/separate the battery metal sides from the tube wall. What also helps is an electrical contact spray that has lubricant. CRC 2-26 spray can for about $3 should be in every modder’s tool bag. Available at Home Depot in the Electrical Department. Great stuff. And it doesn’t stink.
