Solid block type construction of Lead acid batteries:

In the solid block type battery the electrolyte is completely absorbed into a compressed block consisting of porous plates and separators.

The plates are completely supported and therefore a more porous active material paste can be used, this gives better absorption and an enhanced electrochemical activity.

The support given to the plates means practically no distortion and no shedding, therefore no sludge gap is required, all the space inside the cells being used for the plates.

All of these advantage result in a battery that is stronger, less susceptible to vibration damage and has a higher capacity to weight ratio than its conventional counterpart.
