Expanded

At MUTLU BATTERY, in addition to the conventional grid casting method, for both positive and negative grids, we have been using expanded metal (Ex-met) technology in grid production.

Products of all grids series between 35 and 10 Ah of the standard starter batteries intended for the aftermarket are manufactured using this system.  This method consists of pouring the lead alloy in form of a stripe and turning them into stripe shaped grids by cutting and expanding after having them rolled.  The manufactured stripe grid is pasted to render high volumes of homogenous plate production.
