The 152 has a battery tray, which is easier to maintain and spot problems. Attachments Battery-Concorde-RG2411M.jpg (190.72 KB, 24 downloads)

The 152 has a battery tray, which is easier to maintain and spot problems. Because the original battery’s cells each had their own vent. A box was needed to capture these corrosive and/or explosive fumes and vent them safely overboard. The 152’s 24-volt battery was a newer design that vented all the cells internally, with a single vent tube going overboard. In effect, the battery case doubled as the box. -Kirk Wennerstrom President, Cessna 150-152 Fly-In Foundation 1976 Cessna Cardinal RG N7556V Hangar D1, Bridgeport, CT KBDR

This will solve future acid issues and can leave the old box with holes in it depending how big those holes are. http://www.cessna150152.com/forum/ubbthreads.php?ubb=showflat&Number=420626#Post420626 https://www.aircraftspruce.com/catalog/elpages/odysseydry9.php https://www.aircraftspruce.com/catalog/elpages/odysseydry7.php
