Re: [PSUBS-MAILIST] gelled cells



I gotta add this.
 
It's my understanding that the electrolyte has been immobilized by adding a material like fumed silica (Cabosil). This allows the sulfuric electrolyte to stabilize.
 
The problem is that the immobilized electrolyte  may deform and crack degrading the performance of the cell.
 
I used Absorbent Glass Mat (AGM) which is quite a bit different and more expensive.
 
I would have to agree with Phil, the conventional flooded cells are the most cost effective.
