Inside all lead-acid batteries, small particles are formed which eventually fall to the bottom of the battery case where they accumulate. These particles are composed of lead compounds which fall from the surface of the plates during charging and recharging of the batteries. If this debris of mud builds up against the lead plates, short circuits will eventually occur which will result in a defective battery.
In an attempt to prevent that from happening, some manufacturers use battery cases that have molded-in ribs on the inside bottom surface. When the battery plates are installed, the plates will sit on top of these ribs. The intention is to prevent the mud from touching the plates by providing a space below them for the debris to accumulate.
This helps somewhat, but this method has a major disadvantage. When industrial batteries are used in vehicles, such as lift trucks which are subject to many changes in movement and vibrations, the mud formed by the debris can flow sideways. When this mud flows against the vertical side of the ribs, it has nowhere to go except upward where it will hit the battery plates. Molded-in ribs will always have this problem because it is virtually impossible to design a mold to make flow-through ribs.
The patented lattice design of our Bridge Rest support solves this problem by providing a path for the mud to flow under the support ribs. In addition, the mud can freely flow between the cross-bridging members where it can seek a common level. This allows a much larger accumulation of mud at a lower level, thereby extending the life of the battery. We manufacture Bridge Rests in both standard and custom sizes.
