Only open/close when absolutely necessary and if possible use flattop (rechargeable) AAA cells (thanks for advice to previous poster) to relieve door stress. Universal chargers charge these (the ones with adjustable battery size contacts).

My cells and charger coming in a few days and will keep the board updated!

AAAs in a 28S??
It takes N cells.
