I recently purchased a used golf cart, which might be 20+ years old. However, it did have a new set of batteries and seems to be in decent condition for it's age. My only beef is the very heavy, original charger, which probably weighs over 30 lbs., and tries to dislocate my shoulder every time I lug it over to the golf cart. This weighs next to nothing, has a lovely digital display, which shows the charging rate much like the analog meter on the old charger, and has the twin diodes in the back that will tell you when the batteries are fully charged. The meter will show zeros in the amps charging display. I love it. Thanks.
