More battery charger upgrade

The old is out and the almost new is almost installed.

Removing the old stuff was kind of straight forward.  Some things were riveted in place and some screws were used.  I did need to clean up and paint the bottom of the box but that was not anything new to old bagos.  Plenty of rust was under the box probably since it was under the fridge and water or liquids come out of the fridge at times.
