Michael James Geery was born July 15, 1937 in the small town of Missoula, Montana. He quickly developed an aptitude for understanding the workings of cars and motorcycles and building engines. With his mechanical mind, he attended Northrop University in Los Angeles and graduated with a degree in aeronautical engineering with a minor in electronic engineering. His career progressed from being an engineer, selling semi-conductors at TRW, to becoming the western area sales manager for Gates Energy's battery division. Lead acid batteries at that time were new technology and battery chargers didn't exist, so at night he would go home and create schematics so one of his customers could build a battery charger. When that customer didn't want to manufacturer his own, Mike started building them in his garage in the evenings. The demand was so large for lead acid battery chargers that he quit his job and started his own company, Xenotronix. The company went on to build chargers for the movie industry (including battery pack and charger for the original R2D2), military (for the stealth bomber and every battleship in the US Navy and Coast Guard) and medical industry (he built the charger used on the first heart transplant). Other companies reached out to him for charging solutions for such important needs as the Jaws of Life.

He was an inventor, a genius, a problem solver, an artist, and a craftsman. He was the kind of person who could inspire you to great accomplishments, lofty dreams and self-belief. After he inspired you, he was the kind of person that could then point out the easiest path to get you there. He had a tremendous dry and gentle sense of humor, was an excellent storyteller, and loved to laugh. He could build just about anything and certainly design the rest. If he didn't know the answer to something, he would take it apart and figure it out - partially out of his desire to help and partially out of his own curiosity. He was never bothered by squeamish things and always felt annoyed by pain. He had an enormous capacity to love and along with homemade apple pie, maple sugar candy, molasses cookies, rhubarb pie, oysters, sushi, Häagen-Dazs rum raisin ice cream, and really good scotch, what he loved most was being loved and adored by family and friends and feeling the warmth of unconditional love.

He is survived by his son, daughters, grandchildren and great-grandchildren.
