In an effort to reduce battery replacement cost, a poultry meat distribution company based in Malaysia installed 24V Infinitum Desulfators their trucks. Though the trucks are used more regularly than domestic vehicles, the trucks are still parked longer than they are used. This results in the build-up of crystallised sulfation that kills batteries prematurely.
Now with the 24V desulfator installed, the two 12V batteries set in series will not only perform better but will have its lifespan optimised. Below are images of the installation on one of those trucks which took about 5 minutes to perform.
Surface cleaned throughly before installation.
