Manufacturing

We own and operate a full battery production line, which allows us to produce and assemble all of our batteries in house. This is only one of several production workshops, and it is here where the production of medium or large capacity batteries are produced. These specific batteries are narrow, have a long service life, and are high powered solar batteries. Available voltages include 2, 6 and 12V, with a capacity ranging from 24 to 3,000Ah.

Battery containers are made from ABS materials, and are in full compliance with UL94 and UL94V-0 standards. This container is corrosion resistant, making it a great choice for preventing electrolyte leaks.

We also use a lead calcium alloy plate and an additive with a high purity rate, in order to achieve a great mechanical strength, outstanding corrosion resistance and extended service life. Further, to prevent short circuiting between the battery's anode and cathode, each battery is equipped with a high quality AGM (absorbed glass mat).

Positive and negative plates on the AGM separator are key components in the battery when it comes to power generation. Shown here, the AGM white separator is being placed between the positive and negative plates by our expert operators.

After being paired with the plates, the separator is then placed inside a quality box. Once that is complete, we carry out an oxyacetylene gas welding process, which ensures the permanent joint of all products.

Butt welding is a process connecting the positive and negative lead components in a series. We use both butt welding and oxyacetylene welding techniques to achieve an outstanding welding result.

The cover and container of the battery are sealed with an epoxy resin, resulting in a high mechanical strength, outstanding sealing performance, and great acid resistance.

The multifunctional stripping machine cuts and strips wires at a high speed during a fully automated process. As it is computer controlled, wires can be precisely cut to length and stripped.

During the oxy-acetylene welding process, cables are firmly welded to battery terminals.

The colored epoxy adhesive delivers an excellent sealing performance. It is used to distinguish a battery's anode and cathode. Sealed terminals can prevent an electrolyte leakage.

The drying oven is used to cure the epoxy resin at 60°C in an hour.

Finally, an acid filling machine is used to add electrolyte to the battery. The machine is microcomputer controlled, and operates in a vacuum environment. The sulfuric acid is extremely pure, and rated at analytical grades. Due to the low self-discharging rate, the acid filling machine easily controls the amount of electrolytes added to the battery, ensuring a consistence performance between the charging and discharging processes.

Workshop Interior

We own and operate a complete battery manufacturing line, which means all of our batteries can be produced and assembled in house. This is only one of several production workshops. It is built for the production of medium- or large-capacity batteries.

Raw Material

Our battery containers are made from ABS materials. They are fully compliant with UL94 and UL94V-0 standards. The ABS container possesses excellent corrosion resistance, which makes it an ideal choice for preventing electrolyte leaks.

High-quality ABS container

Owing to the use of a lead calcium alloy plate and an additive with a high purity rate, our battery can be provided with an extended lifespan, outstanding corrosion resistance and great mechanical strength.

Positive plate

Negative plate

We have employed top-grade AGM separators which can avoid short circuiting between the battery's anode and cathode.

Plate Enveloping Area

Positive and negative plates on the AGM separator are crucial parts in the battery when it comes to power generation. The AGM white separator is being placed between the positive and negative plates by our expert operators.

The positive plate is being put onto a white separator.

Plates, as seen in the picture, have been perfectly enveloped. Every piece of the plate has a small capacity. After parallel connection, these plates can deliver a large capacity. Every set of the plate has a voltage of 2V.

Oxyacetylene Gas Welding Area

Welding is performed after plates have been enveloped. All of the anodes and cathodes are welded respectively.

We carry out an oxyacetylene gas welding process, which enables the parallel welding of anodes and cathodes. Every piece of the electrode plate is firmly welded, and it possesses superior quality.

Burrs generated in the welding process are removed by our staff. This helps to prevent shorting of anodes and cathodes, and thereby ensure the quality of batteries.

Plates which have been enveloped and welded are put inside the battery container.

Butt Welding Area

Butt welding is a process in which the positive and negative lead components are connected in a series. We adopt butt welding and oxyacetylene welding techniques to achieve an outstanding welding result.

Butt welding has been completed on the semi-finished batteries.

Cover Sealing

The cover of the battery is sealed with an epoxy resin, which results in an outstanding performance, high hardness and excellent acid resistance. The epoxy resin has a strong adhesive force and is not easy to crack. Owing to its outstanding sealing performance, every unit in the battery is not connected in series.

Wire-to-Terminal Welding

Demonstrated here is the high speed, fully automatic, multifunctional stripping machine. It is reliable for cutting and stripping a vast array of wires. As this equipment is computer-controlled, wires can be precisely cut to length and stripped.

These wires have been properly stripped.

Bundled red wires

Bundled blue and green wires

Terminals are welded to the positive and negative electrodes. Then we perform the oxy-acetylene welding process where the wires are firmly welded to battery terminals.

Wires have been welded to the semi-finished batteries.

Coloring

Gluing and coloring are conducted after wires have been welded. The colored epoxy adhesive offers an excellent sealing performance. It is utilized to distinguish a battery's anode and cathode. Sealed terminals can prevent an electrolyte leakage.

Drying

The fully-automatic CNC drying oven can cure the epoxy resin at 60°C in an hour. Drying is performed three times during the battery manufacturing process. Once that is complete, our batteries can deliver an optimal sealing performance.

Curing at 60 degrees Celsius within one hour

Acid Filling Area

Finally, we employ the microcomputer-controlled acid filling machine which can add electrolyte to the battery in a vacuum environment. The sulfuric acid that we use is extremely pure and rated at analytical grade. The amount of electrolytes added to the battery is controlled accurately, which can ensure a consistent performance of the battery.

Battery Charging Area

We charge and discharge every battery in the factory. In order to actuate the battery, charging is completed three times, and discharging is completed twice. This can also ensure the battery is fully charged after leaving our factory. Here we also perform a full range of tests on our batteries for the purpose of quality control.

The computer-controlled charging machine is provided with functions like real-time fault diagnosis, display and alarm. The capacity of every battery can be viewed clearly, which helps to prevent overcharging and power loss.

The status of every battery is clearly displayed.
