I realize they are pressurized but can I drill and fill with oil then put a spring loaded pressure compensator into the drilled hole to create the internal pressure. So the battery would have a constant pressure inside at the surface then it increases as the battery dives to match water pressure. Will that work? I would like to move my AGM's to the outside of Elementary 3000.</div><div id="yui_3_16_0_ym19_1_1459895864470_3648">Hank</div></div></body></html>
