[PSUBS-MAILIST] agm battery

[hank pronk via Personal_Submersibles]

Sean,I don't know, but Alan is an expert in this area, and he has built one.   I suspect I need to use lead acid batteries.  I just happen to have AGM's on hand.Hank

 To pressure compensate the interior of a battery like that, wouldn't you need to use battery electrolyte and not oil?Sean

Alan,Did you successfully make a deep sea AGM battery?    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.Hank
