Summary of Laboratory Reports on the efficacy of Longa-Batt (ProBat).

From left to the right a plate that has never been in contact with electrolyte, a plate of a battery already in use with large crystals that have accumulated on the plate, and a plate treated with Longa-Batt (ProBat) free of lead sulphate crystals.

On the left, electrolyte of a non-treated cell with lead sulphate in suspension This means the sulfuric acid did not return completely to the electrolyte which is now weak. On the right, the electrolyte of a treated cell is clear and strong.

An electrical bulb connected to a weak battery shows a dimmed light. 30 to 45 minutes after adding Longa-Batt LB to each cell, the intensity of the light is noticeable. This can be more precisely measured with a Lumi-meter. It has been observed an increase of 25% to 50% in light intensity. ProBat is very effective in reactivating a weak battery and increasing its capacity.

The beneficial features of this technology are supported by Laboratory Reports.

KOREAN ELECTROTECHNOLOGY RESEARCH INSTITUTE

SUMMARY OF TEST RESULTS

In this case, this Research Institute found that the discharge rate on the tested batteries is much greater with Longa-Batt (ProBat) Battery Life Extender than without the chemical. This means that it takes more time to complete one cycle. As a battery is built for a maximum number of cycles, if the discharge phase takes longer, the capacity is greater and the battery will take longer to reach its maximum number of cycles. Accordingly, this Research Institute has concluded that this inhibition will add to the useable life of a battery.

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 then 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.
