NINJA

What is NINJA:

The deteriorated batteries having a discharge capacity of only 20-30% of their original capacity can be regenerated to 60-90% of their original capacity and that the recovered battery can be used for more than 1 or 2 years.

Add NINJA in a battery every 6 months and extend the life of a battery up to 10 years.

Features & Benefits

Extend battery life up to 10 years when NINJA is added and proper charging is carried out once a 6 months.

Extend battery life 3 – 5 years when used in batteries deteriorated by sulfation.

Batteries with 20 – 30 % remaining capacity will increase to 60 – 90 % when NINJA is added and regenerating charging is done.

Once NINJA is added, its effect lasts for 6 months or longer. The amount customers have to add is as follows.

Note: 1 pack of NINJA contains 6 NINJA sticks (1g).

Significantly reduce battery costs, maintenance costs, disposal costs and environmental impact.

How to use.

We recommend the following processes (1 and 2). Process (1) is for batteries still in use, while process (2) is for deteriorated batteries that have been removed from a car, truck, etc…

Process(1): Add NINJA to each cell of your batteries.

Process(2): The deteriorated and replaced batteries require a special two-step (3 days) charging after the activator addition. Require to use a special battery charger which can charge beyond 16V. The first step operation requires one to two days to reach upto 14.5V, but the second step won’t need more than one day to reach 16.5V.

The battery deterioration (capacity reduction to 20 – 30% of the original capacity) is recovered by removing the sulfation

How it looks

1 pack of NINJA contains 6 NINJA sticks and they have powder inside as you can see below.

How NINJA Works:

(1) Cause of lead-acid battery’s deterioration: In the past, it has been said that deterioration of battery comes from deterioration of positive terminal of the battery. When positive terminal is deteriorated, charging voltage does not go up beyond 13.0 ~ 13.5V. And then, charger keeps supplying big current judging battery is not fully charged yet. It causes over-charging and damages positive terminal of the battery.

(1-a) From many years study and tests, we’ve found that

“Major reason for deterioration of battery” comes from deterioration of NEGATIVE terminal.

Deterioration comes from Sulfation of negative terminal.
“Sulfation”: Lead sulfate changing to large crystallines.
Sulfation reduces charging capacity of the battery.
“Cause of Sulfation” comes from reduction of hydrogen over-voltage.

From our research, approx. 80% of lead-acid batteries were replaced and abandoned due to sulfation.

(1-b) Other reasons of battery deterioration include:

Over-charging: When electrolyte temperature is high, positive terminal is corroded and deteriorated. Deteriorated positive terminal causes over-charging of the battery.
Deep discharge: When too big current is discharged, it reduces battery charging capacity.
Shortage of water in the battery: It causes increase of electrolyte’s specific gravity, and then it causes insufficient charging.

(2)NINJA will dissolve within the battery cell gradually, and its main component,organic polymer particles will be absorbed on the electrodes. Then, it works to avoid sulfation which is a cause of deterioration of battery and works to activate electrodes by breaking up large crystallines (i.e. sulfation).

Other activators/additives until now could not solve the fundamental problem with deterioration of lead-acid battery, because those additives could not eliminate sulfation.

Why NINJA is special and unique?


Until now, most of additives or activators for lead-acid batteries use fine powder of solid materials such as barium sulfate, lignin and carbon black for negative electrode. They are generally called an “expander”. But, none of them can eliminate fundamental reason (sulfation on the negative terminal) for battery deterioration. They only extend battery life temporarily.
We found that organic polymer soluble in the acid electrolyte is very effective in extending the life cycle and improving the discharge capacity of lead-acid batteries.
NINJA reduces and eliminates sulfation, and works to activate electrodes by breaking up large crystallines. With addition of NINJA, water and proper charging, battery is regenerated and battery life can be dramatically extended.

Remarks:
NINJA won’t be effective for lead-acid batteries where their electrodes and terminals are detached from battery cells, or severely damaged mechanically.

Charging Test: without and with NINJA.

Below is the result of 3 days and 1 day battery charging experiment with and without NINJA by different type of battery chargers.( 2 A and 5A)

Note: We used four 3 years old batteries 40B19L to investigate the ability of battery for charging.

A voltmeter was used to measure the voltage between two points in the battery system.
Ampere (Electric current) was also measured using an ammeter .
Specific gravity of sulfated acid was measured using hydrometer as you can see below.

As you can see above, only 2 battaries with NINJA reached to its charge level 15.0 V or above.
And t
he specific gravity of sulfuric acid also increased rapidly so we can say that the lead sulphate was dissolved in electrolyte effectively.

2 Minutes of Discharging Test: with and without using NINJA

We used a Nicrom wire with 150 A to test whether 4 batteries can start a car engine or not.
If the batteries satisfy the followings, we can say that the batteries can start a car engine without problems and can be used one more year.

1. The voltage of the batteries keep 9 V or above.
2. The ampere of the batteries keep 100 A or above.

Below is the result of battery discharging experiment with and without NINJA.

Without NINJA

The diagram below shows the ampere and voltage of the battery which was charged by 2A previously.

As you can see above, the one with NINJA only satisfy 9V and 100 A.
By seeing the above result, we can say that NINJA was effective for these 2 batteries.

Now let’s try to use NINJA for batteries with a bad result and see the difference between them.

As you can see above, the 1st battery with 2A battery charger was regenerated properly by using NINJA and reached to 15 V.
The 2nd battery is not regenerated properly. Let’s investigate the cause in the following chapter.

The reason why a battery was not regenerated properly

We first noticed that the specific gravity of sulfuric acid in cell 3.
As you can see, it was too low (only 1.17) after using NINJA.

Scientifically, we can say that the lead sulfate didn’t melt properly and instead of melting the lead sulfate there was only an electrolysis of water.

Above can be happened when there are any active material on the lead plate caused by internal short circuit.
Note: Internal short-circuit is happened when there are over dischage.

Summary and Conclusions

Deteriorated batteries in use can be rejuvenated from sulfation base on the specific gravity increase during use in trucks, golf carts and forklifts when NINJA is added.

Deteriorated and abandoned batteries can be regenerated by a two-step(1,2 3 days) charging operation after the addition of NINJA.

Battery recovery from sulfation only slowly takes place by the charge-discharge procedure.

Batteries which have a internal-short circuit(known by the specific gravity of sulfuric acid. (stay arround 1.10~1.18)) can not be rejuvenated.
