Review on Battery Rejuvenator BLS-36N: Advanced 36v Battery System Desulfator and Life-saver by Carlos Burrows

Easy to install on a 1993 EZ-GO golf cart. I installed it under the reversing switch where there was room for it. Used thermal paste to use the metal plate for heat dissipation. One caveat when installing: note that there is a support rod along the base inside that must be taken into account when determining mounting holes. I barely had enough hole height to attach the base of the cooling fins to the sheet metal panel. The only downside I see is that the status LED should be replaced with one that gives more side lighting. The LED currently focuses the light forward and is hardly visible from the side. Due to the position on a vertical surface, I couldn't tell if the light was on during the day, even though it was protected from direct sunlight. The mirror was needed to determine if the lights were on. I can't say yet whether this will help the batteries, as they are in good condition despite being 4 years old.
