I blame myself for my motordrive battery failure because I failed to follow the instruction manual's statement of "It should become a habit to charge the batteries completely before every lengthy period of idleness and, to prevent a complete discharge, also to recharge them regularly at room temperature approximately every six months." I recently thought I'd also ruined a Metz CL4 flash unit because I put it in a drawer for several years, failing to occasionally charge its capacitor "every three months", but multiple attempts to get it to fire up with fresh AA batteries eventually surprisingly, finally resulted in it powering up. Phew!
