Test of the battery desulfator. It's been 9 years !

　　The report of "Desulfator" - Spec.2

■June 12, 2005


Battery check	No1 cell	No2 cell	No3 cell	No4 cell	No5 cell	No6 cell
Voltage is 12.61V	←　From plus terminal to minus terminal　→

All the cells show over 1.26. The color of the battery liquid is clear.
I checked the CCA value this time. The genuine Mercedes Benz battery has 450A (Cold cranking current).

Normal CCA value : 450
This time CCA value : 369
369×1/450×100 = 82% (against the normal)

Japanese desulfator was installed on the Merceds Benz which had been 6 years since new. Therefore, CCA value must had been dropped at that time. Now this battery shows that although voltage and liquid density are normal, CCA value drops. This means the element plates are getting be old.

Although this battery has been 8.5 years since new, it's still working. I'm going to check it out on Dec. 2005 next time. If I recognized the senescence of the battey, I'm going to decide that it should be replaced or not.

This long-term test shows that the lead battery can work for a long time by preventing the sulfation even the old battery. It is said that the element plates of the lead battery have the changeable volume when charged and discharged. This phenomenon influences the battery permanence. I recognize that the high quality battery has the high performance element plates. On the other hand, the cheap battery has a short life because of the low quality elementplates.

Battery check	No1 cell	No2 cell	No3 cell	No4 cell	No5 cell	No6 cell
Voltage is 12.60V	←　From plus terminal to minus terminal　→

This is a "density measure" for the lead battery. ↑
The open type battery is filled up by the battery liquid which consists of fine water and sulfuric acid.

The measure stick, which has red, yellow and green zones, shows the density of the battery liquid.

All the surface of the battery liquid locates in the green zone.
The battery liquid is clear.

The relative density of the battery liquid goes down a little bit than the previous check. Therefore, it was guessed that the element plates were getting be old.
This battery has been working since new, therefore, it's a sufficient result. It's been 8 years !

However, I found the fact on the car maintenance document. This Mercedes Benz was checked by the Mercedes Benz car dealer on Dec. 1.

　　Sorry, this document is written in Japanese.

This document shows that a bottle of fine water was refilled into the battery.
This means the battery liquid became a little bit thin.
Therefore, The relative density of the battery liquid goes down slightly than previous.

■Couclusion

This battery still has a good condition. It's been 8 years since new !

The voltage is 12.60V.

As you know, it's impossible to use the car battery for 8 years. This result shows that the used lead battery can work for 8 years by using "Desulfator".
This test to be continue......

Caution!
If the battery was faced the lack of battery liquid, refilled the chemical liquid, otherwise got a strong shock physically, the element plates might be spoiled. If the battery was faced the physical troubles, the battery life might be shorter.
