2. Is it possible to recover a dead battery with charging un-acceptance which is unsold or in stock for long time?


Yes, if you are using our Smart Pulsating Technology maintainers and recover it as our unique repair process. Although our on line battery protector, EV Chargers and Maintenance Chargers or BMMS products are designed for keeping good, new batteries in peak condition for a longer period of time, our off line repair system have the ability of being used to bring batteries that will not accept and hold a charge back to useful condition.


Here's what you do: Use a multimeter or other kinds of digital battery analyzer to check the OCV value or IR Value to determine how to recover it use our off line battery repair system

The ideal way to recover a dead battery is to use our 2V/12V Battery Restore System (Battery digital pulse charger, Battery pulse maintainer and Discharge tester). Make sure the cells are filled with distilled water and attach the battery to the Pulse Charger or Maintainer. The more info of recovery process, please take a look in our product lists of "Battery Smart Pulse Restore System".

For these dead batteries caused by sitting on shelf unsold for long time even if more than 3~5years, we promise you that can be recovered as new battery conditions. Do not worry, just follow us.


3. How long does a battery desulphation repairing process?

It depends on the battery type, Capacity Volume and battery sulphaion conditions. This is not fixed and our different device application with different desulphation cycle time because of using different pulsating current

On average, if you use our off line battery repair system:

1) 12/16V 4.5~30 Ah battery, the desulphation time of repairing process is about 24~48hours

2) 12V 20~300Ah battery, the desulphation time of repairing process is about 48~72hours

3) 2V 200~1000Ah battery, the desulphation time of repairing process is about 4 Days

If you use our battery protectors and smart chargers, it is working anytime and anyplace 24hour every day. And After installed more than 1-3 months, the battery will be desulfated and kept in peak conditions


4.What makes Daceen-sz products different from other battery charger and maintenance products available on the market?


We offer many Battery Protector, EV pulse charger or Maintenance Charger and Battery smart pulse repair system that utilize our revolutionary and patented high technology. This technology is designed to help prevent the main cause of battery problems and failure: sulfation buildup and related problems. Some devices or maintenance methods may claim to provide the same benefits as ours, but most of them merely try to "maintain" the battery by charging them on a larger constant basis or chemical liquid addition. The problem is too much charging and chemical molecules will ultimately overheat and damage the lead plates. In other words, the "cure" could be worse than the disease when not done properly and hurt battery.

Some other equipment even declares to eliminate sulfation crystals from the cell plates. But, this too is usually done by over charged the plates with higher voltage in order to literally knock the sulfates loose. use this method, only a few sulfates are removed as active plate material sheds and falls useless away from the battery plates. There is no doubt that the design life of the battery is shortened although the battery has recovered a little capacity in the short term

What makes our technology so unique and effective is a distinct pulse waveform. This Smart Pulse:

1) Has a strictly-controlled rise time, smartly changeable pulse-width, frequency and amplitude of current and voltage pulse upon the sulpation crystals itself.

2) Different frequencies and harmonic waveforms in pulse charging resonate with PbSO4 crystals to be broken up;

3) Online/offline restore of desulphation technology, suits for all lead-acid batteries failure due to sulphation;

4) Best desulphation effect and can be recycled many times, restore 90% above as new one ;

5) No damaged to the positive and negative plates of the battery, improves battery efficiency and lengthens battery life;

6) More than 20 years of applications and field validated in Military and All industry with high performance and being Trusted



5.Can they be used on more than one battery at a time?


It depends on the model.



6.Which product should I use when storing my car or truck for long periods of time?


We suggest you use the 12V Battery Digital Pulse Charger (Model:12VC300Ah) if stored indoors with access to AC power and when it is fully charged, it is better to be recovered by our device of 12V Battery repair instrument for 24~36hours when you have enough time. Besides preventing sulfation buildup, they also prevent the normal loss of battery power no matter how long your vehicle or equipment sits unused -- even months at a time.


If you need to keep multiple batteries maintained, then the 12V UPS Charger Restorer Tester all-in-one is ideal.


Remember that under normal conditions a starter battery will lose 1% of its energy a day while the car sits unused. That means it will not take long for a battery to become completely discharged, especially if it was not fully charged in the first place. So first job is starting your car or truck regularly and install our start up battery protector, that will Charge, Maintain and Condition the battery every day. Then extend your battery life doubled than before.

But, based on lab testing, our 12V/24V start up battery protector will maintain a 12/24V battery for approximately 2 to 3 months off a full charge if left unattended. We're not saying the car or truck will always start at that point, but the battery will be free of sulfation buildup, will be able to be jump-started into action by a Emergency jumping power supply, and it will recharge and hold a charge like a new battery when car driving.



7. What is the meaning of [off line battery repair"

When the batteries are not used and connected in the circuit as power supply. You should take off the battery bank, then connected to the repair system cell by cell. It is off line battery repair.

Conversely, we call it on line battery protection.


8. Will battery protectors benefit or harmful to other electrical components on my car?


Yes. it is benefit not harmful to other components on your car.

By maintaining your starter batteries in new condition, your alternator does not have to work as hard at recharging your car once it has been started. The battery will accept a charge more readily and faster so alternator life should be extended. Also, by maintaining available starting current CCA in your battery, there will be more available energy going to your starter. The engine will turn over faster, so your starter should last longer as well.

So, according to some experiences data, that benefit will help you reduce oil consumption



9.Outside of sulfation damage, what are other common causes of battery failure that Daceen-sz Technology will help?


Other common causes of battery failure (plates softening, shedding and overcharging, etc.) are directly related to sulfation buildup. For example, according to Authoritative electrochemical works named [Battery Manuel" by Tianjin University, softened plates may be caused by: "being overcharged while sulfated or stored in a deeply discharged state." Sulfate buildup weakens the plates to a point where batteries must be overcharged to accept energy. This will then overheat and warp, or "soften," the plates. This [Battery Manuel" works also relates shedding of the plates to sulfation buildup. It states that, "If material has shed from the plates in small chunks, high charging rates on sulfated plates can be the cause."

All in all, each of these and other common causes can be avoided in most cases through the use of our products. And the earlier you use our products to your battery, the longer life will be extended.


10.Outside of Flooded batteries, will Daceen-sz products work on GEL or AGM cell batteries?


Yes.

They work on any types of lead-acid battery even if the lead carbon battery. This includes all common flooded lead-acid batteries and sealed "maintenance-free" batteries, including VRLA, Absorbed Glass Mat (AGM) and GEL cell battery types.



11. How quickly will sulfation buildup occur on a brand new battery? And how quickly will sulfation re-buildup occur after being repaired?


The rate of sulfation buildup on a battery will vary greatly depending on battery state of charge, usage, age and condition. It will occur faster on batteries that are used infrequently.


Also, keep in mind that even brand new batteries must already be sulfated when they are installed in applications or in transit of logistic .So, since sulfation buildup is likely to occur whenever batteries are neglected for long periods of time, it can happen in a battery whole life whenever it used or not.

The real question is, if all of the lead sulfate crystals are not turned back into lead, how long does it take before they become so hard that they can not be converted or how quickly will sulfation re-buildup occur after being repaired? The answer is that varies--it might be weeks or months and depends on a number of factors such as the quality of the lead, temperature, plate chemistry, porosity, Depth-of-Discharge (DoD), electrolyte stratification, etc. The longer sulfation occurs, the larger and harder the lead sulfate crystals become. The positive plates will be light brown and the negative plates will be white.

Thus, sulfation is a huge problem for lead-acid batteries not being used, idled on a dealer`s or DC`s shelves, or in a UPS system standby deep discharged due to power cut, especially in hot temperatures leading to water lost.


12. Since sulfate buildup occurs more often with infrequently-used batteries, will I need Daceen-sz Technology even if a vehicle is operated on a frequent basis, like a car, truck,forklift, and EVs?


Absolutely.

Even frequently-used batteries charged by the alternator on a consistent basis may suffer from sulfate accumulations. This is especially true for start up battery of cars, trucks, buses and power battery of Forklifts, E-Vehicles and Golf carts and other vehicles.


According to actual application cases and , it is possible for a vehicle to develop an undercharged battery if it is constantly driven at slow speeds and left idling for long periods, as in heavy traffic and combined with high electrical load conditions. If a vehicle is moving at slower speeds, idling a lot or suffering from an overtaxed electrical system the alternator is not allowed to charge at an optimum rate. The result is a battery that is not fully charged even though the vehicle is running all day. And since it isn't fully charged, it will begin to sulfate. A vicious circle is then created because the more the battery sulfated, the less energy it will accept and the battery will be undercharged even more. Finally, it is failed earlier because of[Battery Permanent Sulphation".


It is necessary by keeping the battery installation with Battery protector or regular maintenance every 6 months. Maintaining battery plates clean and keep battery like-new conditions for long time, successfully solve the problems above and increase the battery capacity leading to extend battery life.



13.Is it true that charging batteries in reverse polarity will desulfate the plates and prepare it for a better recharge?


Absolutely not. Keep in mind never do that.

For safe, only use our pulse technology products to desulfated and install protector to disturb sulfation re-buildup.


14.How about the large current maintenance tools and chemical liquid addition method?

Not good

Actually, in the short term after being dealt with by large current and chemical addition, there is a certain effect in the following 6 months not more than 12 months. But it will hurt your battery plates or change your battery electrolyte physical properties. This method just can be used for only once for a given battery.


15. Will weather or temperature affect my battery?


Yes.

Temperature and weather are a major factor in battery performance and life. At higher temperatures there is dramatically more chemical activity inside a battery than at lower temperatures. Proper ambient temperature is very important for the longer life: Too high temperature will lead the battery to be overcharged and water lost. Too low temperature will lead to battery deficit charged, which will shorten battery life. Therefore, it is required that the ambient Temp is about 25℃, and floating charge volt value is also set based on 20-25℃ . But in application, the battery is generally charged in the range of 5-35℃.

What many people don't realize is that extreme cases of heat and cold will increase the speed of sulfation buildup. When the weather starts to get hotter, the rate of sulfation buildup will actually double for every 10-degree increased. That means that if the temperature increases 20-degree, the rate of sulfation buildup on battery plates will increase 4times than before. So-.batteries stored or installed in vehicles in hotter weather have the high potential to earlier failed due to battery sulfation, much sooner than in cooler weather.

By the way, remember that the battery's electrolyte can be actually frozen if the battery is in an advanced state of discharge, and this could physically damage the lead plates:

1) At 1.270 specific gravity (100% charged) battery acid will freeze at -64℃,

2) At 1.200 specific gravity it will freeze at-27.5℃,

3) At 1.140 specific gravity (completely discharged) it will freeze at only -13.5℃.



16. Will Daceen-sz products, such as protector and chargers damage electrical systems on cars and other E-vehicles?

No, don`t worry about it.

It is not possible for any of our products to damage the electrical system on any vehicle. We have done many case testing and verification from 1998. Especially installed into military vehicles and 0% failure rate.

We are smart pulse technology without any damage to battery which had been verified in lab by a Brazil start up battery factory.


17. Will Daceen-sz products repair battery for many times?


Absolutely! You can test it as you want.



18.How do we believe that your technology is a kind of non-damaged desulfation method?


A Brazil start up battery factory named Pioneiro Batteries, they did the testing and verification of our protector which installed on a starter battery to be charged and discharged circularly, The times of charging and discharging was increased about 1500~2000 loops than the battery without our protector. That means our technology is a kind of non-damaged desulfation method



19. Do any Daceen-sz products work on 6V/8V/48V/60V/72V lead-acid batteries or banks?


Yes.

Although all of our products are designed for 2/12-volt basis. But we have all products or solutions for 6V/8V/12V/24V/48V/60V/72V lead-acid battery desulfation.
