EXCERPT FROM LONGA-BATT (NEE PROBAT) LAB REPORT
SUMMARY OF LABORATORY OBSERVATIONS
On the basis of the controlled laboratory investigation made by this organization, we have concluded the following:
When used according to the manufacturer's directions, a normal, mechanically sound, lead acid battery is not harmed by the use of LONGA-BATT (PROBAT).
In those cells treated with LONGA-BATT there was found to be less schedding of active material and the material in a softer condition.
Further, as against some disintegration in untreated cells, the grids were found to be firmer in the treated batteries.
The examination indicated that the positive plates from treated cells showed a softer and finer texture of the lead peroxide, their color being red-brown. However, in those untreated cells, the light red-brown of the peroxide was very clearly defined in the grids and was quite brittle.
Under identical conditions of charge, LONGA-BATT treated cells resulted in a higher specific gravity reading in less time than similar untreated cells when starting with discharged, moderately sulphated cells.
Under identical conditions of charge and discharge, on the average those cells treated with LONGA-BATT operated cooler than the untreated cells. (See Graphs #1 and #2).
Upon comparison with untreated cells, those cells treated with LONGA-BATT indicated a more effective, that is, higher charging efficiency.
An extensive internal examination indicated that sulphated cells treated with LONGA-Batt were in better conditions mechanically than those cells which were untreated.
It was also observed by this laboratory that the separators in batteries treated with LONGA-BATT appeared to suffer less physical deterioration than the separators of untreated batteries.
Extensive internal examination indicated that when LONGA-BATT was added to cells containing sediment, the amount of sediment was decreased when the battery was on charge and when it was not on charge.
Laboratory observations indicated that LONGA-BATT treated cells when on charge have a distinctly different appearance from untreated cells on charge. The gas bubbles evolving in the LONGA_BATT treated cells were much smaller than those evolved in the untreated cells.
In those cells treated with LONGA-BATT, both in the new batteries and in the mechanically sound sulphated batteries, the conversion of the desirable soft, spongy, porous mass of material of the grid surface of the negative plate into a harder, brittle, less porous - this is, sulphated condition, is inhibited. Accordingly, we can conclude that this inhibition will add to the useable life of a battery.
