How does a battery work?

A:A battery stores electricity for future use. It develops voltage from the chemical reaction produced when two unlike materials, such as the positive and negative plates, are immersed in the electrolyte, a solution of sulphuric acid and water. In a typical lead-acid battery, the voltage is approximately 2 volts per cell, for a total of 12 volts. Electricity flows from the battery as soon as there is a circuit between the positive and negative terminals. This happens when any load that needs electricity, such as the radio, is connected to the battery.
Most people don't realize that a lead-acid battery operates in a constant process of charge and discharge. When a battery is connected to a load that needs electricity, such as the starter in your car, current flows from the battery. The battery begins to be discharged.
In the reverse process, a battery becomes charged when current flows back into it, restoring the chemical difference between the plates. This happens when you're driving without any accessories and the alternator puts current back into the battery.
As a battery discharges, the lead plates become more chemically alike, the acid becomes weaker, and the voltage drops. Eventually the battery is so discharged that it can no longer deliver electricity at a useful voltage.
You can recharge a discharged battery by feeding electrical current back into it. A full charge restores the chemical difference between the plates and leaves the battery ready to deliver its full power.
This unique process of discharge and charge in the lead-acid battery means that energy can be discharged and restored over and over again. This is what's known as the cycling ability in a battery .

What is the difference between AGM battery and GEL battery?

A: Both Gel battery and AGM battery belong to valve regulated battery type, and the biggest structure difference lies in the separator and electrolyte. GEL battery generally adopted the separators made of organic materials such as PVC or phenol-formaldehyde resin, while AGM battery mainly adopted absorbent glass mat separators. The electrolyte of Gel battery is in the state of resembling gelatin, looks like Vaseline, but the electrolyte of AGM valve regulated battery is liquid absorbed in the absorbent glass mat.
The advantage of GEL battery focus on the service life, capacity stability and in the absence of thermo runaway, etc.
The advantage of AGM battery lies in the good performance of high rate discharge ability and good price, etc.

What is sulfate of batteries?

A:Sulfate is the formation or deposit of lead sulfate on the surface and in the pores of the active material of the batteries' lead plates. If the sulfate becomes excessive and forms large crystals on the plates, the battery will not operate efficiently and may not work at all. Common causes of battery sulfate are standing a long time in a discharged condition, operating at excessive temperatures, and prolonged under or over charging.

Why does born plate sulfate?


1. Inadequate first charging or long interruption time of charging;
2. No sufficient charging for long time;
3. No timely recharging after discharge;
4. Often excessive charging or deep discharge with small current;
5. Electrolyte density or temperature is too high so that lead sulfate will form and hard to decompose.
6. Lay the battery aside for a long time and without any regular charging;
7. Electrolyte is not pure and large self-discharge;
8. Internal short-circuit or leakage of electricity caused by the water on the surface of battery.
9. Barely plate partially sulfated because of low Level of internal electrolyte liquid surface..

Are lead acid batteries recyclable?

A: Lead acid batteries are 100% recyclable. Lead is the most recycled metal in the world today. The plastic containers and covers of old batteries are neutralized, reground and used to the manufacture of new battery cases. The electrolyte can be processed for recycled waste water uses. In some cases, the electrolyte is cleaned and reprocessed and sold as battery grade electrolyte. In other instances, the sulfate content is removed as Ammonia Sulfate and used in fertilizers. The separators are often used as a fuel source for the recycling process.

What causes battery failure?

A: Battery Application and Installation
● The battery being is not being used in the application for which it was designed
● The battery is not the correct size for the application
● The equipment has excessive electrical accessories
● The battery cables have not been properly adjusted to fit the battery terminals
Service and Maintenance
● The battery has been stored for a long time and no supplementary charge
● The equipment setting parameters for battery do not according to supplier’s recommended and do not adjust
● Battery temperature compensation functions do not turn on and properly install the battery temperature probe.
● Battery bolts loosened or over-torquing
Visual Inspection
● Battery connection is wrong
● Container or cover show signs of stress, damage or high temperature.
