Battery Construction


ComponentPositive plateNegative plateContainerSafety valveTerminalSeparator

 

Electrolyte

 

Raw MaterialLead dioxideLeadABSRubberCopperFiberglass

 

Sulfuric acid

 

  

1. Container/Cover: Made of  ABS Plastic from Taiwan

 

2. Negative Plates: Use the special PbCa alloy grids, optimize the recombination efficiency and less gassing.

 

3. Separator: Import high quality AGM separator.

 

4. Positive Plates: Thick PbCa grids minimize corrosion and prolong life.

 

5. Terminal post: Cooper material with maximum conductivity, enhance the high current rapidly.

 

6. Vent Valve: Allows the release of excess gas automatically for safety.

 

 

Q:How to determine the battery is good or bad?
Observe the battery electrolyte is turbid, turbidity that the battery positive plate softening. Observe the bottom of the battery whether there is sediment, if the plate off the battery capacity has been inadequate. Hand hit the battery two electrode piles If you hear an empty voice that pole pile and plate break. With a thick wire short-circuit positive and negative pile observation of the battery filling holes, such as the discovery of a bubble appears that the interval has been damaged.
Q:What is the meaning of the battery above 12v65Ah?
12V is said to be the voltage, 65Ah is the current. (A is the unit of current. H is the time unit .1 hours.)
Q:How does the battery increase the voltage?
Chemical energy can be converted into electrical energy device called chemical battery, generally referred to as the battery. After discharge, the internal active material can be regenerated by charging - the electrical energy stored as chemical energy; chemical energy can be converted to electrical energy again when the discharge is required. This type of battery is called a battery (Storage Battery), also known as secondary battery.
Q:How to repair the battery?
Charge the battery at constant voltage. It is the beginning of the time, using 0.1C ~ 0.25C current charge, to 16.2V later, by reducing the current method to maintain the charging voltage, until the charge current drops to 0.03C when the stop charging.
Q:The role of the battery?
Battery is a kind of battery, its role is to be able to save the limited power, in the right place to make 6v4ah emergency light battery. Its working principle is to convert chemical energy into electricity.
Q:How to deal with waste batteries?
In addition to lead-acid batteries, all kinds of batteries are dissolved in sulfuric acid, and then by means of ion resin from the solution to extract a variety of metals, raw materials obtained in this way than the heat treatment method is pure, so the market price is higher, and the battery contains 95% of the various substances can be extracted.
Q:80ah how much battery storage capacity?
The size of the battery storage power refers to the battery capacity. Battery capacity is generally calculated in AH (safety). You 80Ah battery capacity is 80Ah, meaning that if you discharge current to 80A, you can put an hour.
Q:What are the advantages of maintenance-free batteries?
The advantage of a maintenance-free battery is that the service life is twice as long as the dry battery! And in the use of the process without maintenance! The voltage is also relatively stable.
Q:How should the battery be well maintained?
Voltage check the state of the battery standard voltage should be maintained between 12.2 ~ 12.7V. If the voltage is too low should be charged, the charge should be kept small charge for a long time. Battery charging need to use a professional charger, the owner will not try to charge their own, the owner can only keep the engine running on the battery can be charged. If the battery aging should be replaced.
Q:Lead-acid battery how to maintain?
After 5 hours of repair, the excess electrolyte is sucked out with a straw, and if the electrolyte is sucked out into black, it indicates that the battery is severely grounded and that the battery is difficult to repair.
