Batteru Features :


1. Maintenance-Free Operation 
Absorbent Glass Mat (AGM) technology ensures efficient gas recombination up to 99% and freedom from electrolyte maintenance. During the expected float service life of Prostar batteries, no need to check the specific gravity of the electrolyte or add water.
2. Good Discharging Ability
Tight assembly technology ensures an excellent high-rate discharge performance.
3. Long Service Life
A unique corrosion-resistant grid alloy ensures Prostar batteries have long service life.
4. Low Self Discharge
Using high purity raw materials ensures Prostar batteries have less self-discharge.
5. Environmental & Non-polluting
Gas Recombination technology ensures the battery high seal reacting rate, which can prevent the acid fog from separating out.
6. Safe & Reliable
Efficient venting system automatically release excess gas when the pressure rises above the normal level & reseals the valves when it returns to the normal rate, which can protect the battery from bursting.

Applied Scope :

1. Communication Systems: Switch, Microwave Stations, Mobile Base Stations, Data   Centers, Radio and Broadcasting Stations
2. Motivity Field: Robots, Electric Toys, Electric Tools & Portable Vacuum Cleaners
3. Solar & Wind Power Generation Systems
4. Signal System & Emergency Lighting Systems
5. EPS & UPS Systems

Q:What are the hazards of battery over discharge?
Excessive discharge can seriously damage the battery's electrical performance and cycle life.
Q:What is the difference between a maintenance-free battery and a conventional battery?
Different materials will produce a different phenomenon: the traditional battery in the course of the use of the phenomenon of liquid reduction occurs, because the antimony on the grid will pollute the sponge on the negative plate of pure lead, weakened after the full charge of the battery Electromotive force, resulting in excessive decomposition of water, a large number of oxygen and hydrogen, respectively, from the positive and negative plates to escape, so that the electrolyte reduced. With calcium instead of antimony, you can change the fully charged battery back electromotive force, reduce the overcharge current, liquid gasification rate decreases, thereby reducing the loss of electrolyte.
Q:What is the meaning of the battery above 12v65Ah?
12V represents the rated voltage. 65Ah indicates that the battery capacity (ie 1 ampere current can be used for 65 hours).
Q:The role of the battery?
Battery is widely used, can be used for ups, electric cars, scooters, cars, wind energy solar systems, security, and so on.
Q:How does the battery increase the voltage?
With the same battery pack in series; if the required current is relatively small, you can use DC-DC module.
Q:What battery does the van use?
General use of lead-acid batteries. Electrode is mainly made of lead and its oxide, the electrolyte is a sulfuric acid solution of a battery. English: Lead-acid battery Discharge state, the main component of the cathode is lead dioxide, the main component of the negative lead; charge state, the main components of the positive and negative are lead sulfate. Divided into exhausted batteries and maintenance-free lead-acid batteries.
Q:What is a maintenanceable battery?
Maintenance-free battery due to its own structure on the advantages of electrolyte consumption is very small, in the life of the basic need not add distilled water.
Q:How does battery activation work?
Always keep the battery surface clean. Found that the surface of dust and acid, it should be timely wipe, wipe can be wiped with soda water wipes wipe again, after rinse with water.
Q:80ah how much battery storage capacity?
Is 80AH. Understood to discharge at 80 amps for about 1 hour (but not to say that after 1 hour is finished, there is still electricity). In theory, this is your battery power.
Q:How is the capacity of the battery defined?
100AH capacity of the battery, fully charged after the 100A current discharge can be an hour to put the power finished. 50A current is 2 hours put away! 20A is 5 hours! Of course this is the theoretical value, in fact it is impossible to have a constant current discharge.
