About Our Factory

At JuLi, we own and operate a complete battery production line in order to carry out the development and production of a full line of rechargeable batteries.

This is the first production workshop, where the production of solar batteries with mid to large capacities is done. These batteries are primarily narrow-shaped, high power batteries with a long service life, guaranteeing customers receive long-term power supply when the need it. Voltages include 2V, 6V, 12V, with a capacity ranging from 24AH to 3000AH.

The battery cases themselves are made of ABS material that is in line with UL94 and UL94V-0 standards. The cases are also corrosion resistant, and prevent electrolyte leakage, guaranteeing customer usage safety.

The use of an electrode plate made from a high tin alloy ensures the electrode grid is stronger and more corrosion resistant, which in turn prolongs the battery service life.

For preventing short circuits, the batteries are made of high-quality, imported AGM separators.

  • Battery case
  • High-quality ABS battery case
  • Electrode plate
  • The anode plate
  • The cathode plate
  • Separator
  • Front side of the separator and back side of the separator

The positive and negative electrode plates, together with the AGM separator, are critical components when the battery is generating electricity. Users place the cathode plate lug facing one direction, and put it in the white AGM separator while simultaneously placing the anode separator on the AGM separator, with the plate lug pointing in the opposite direction. The AGM separators are then folded, with a cathode plate placed inside the folded separators.

  • Place the anode plate
  • Finish the electrodes combination during the plate wrapping process

After the plate wrapping process, the plate group is placed in a customized iron box with the anode and the cathode facing the same direction. A specialized comb plate needs to be attached, and lead parts arranged around the plate group. The next step is welding. Using an oxy-acetylene welding process, not only are the positive and negative plate lugs welded together, but the lead parts in each weld group also need to be welded.

Due to its high mechanical strength, excellent sealing effect, and strong acid-resistance, we use an epoxy resin adhesive to seal the battery cover and its case. In order to cut the wires into even lengths and carry out high speed wire stripping, we use an automated computer shell wiring machine.

  • High-speed multifunctional automatic computer
  • Wire-stripped Lead head
  • Stripped red wire
  • Stripped blue and green wires

The use of oxy-acetylene helps to firmly weld the wires.

We use epoxy resin as coloring glue, which features a great sealing performance in order to distinguish between the positive and negative anodes, and prevent electrolyte leakage.

It takes one hour to solidify the epoxy resin at 60 degrees centigrade with an oven.

The last step is filling the battery with the electrolyte, using a microcomputer-controlled vacuum acidification machine. This machine ensures an outstanding battery performance during battery charging and discharging cycles.

Refuel the electrolyte in a vacuum under the control of microcomputer.

All the batteries are charged and discharged in the factory. After charging for three times and discharging twice, the batteries are fully activated. The battery charger is controlled using a computer, and can screen batteries with different capacities in order to guarantee their quality and capacity. The charger will also clearly note each definitive battery capacity.
We carry out sampling checks to ensure final battery quality.

  • The charging condition of each battery can be clearly observed

This is the second production workshop, where the production of small capacity batteries is carried out.
Voltage: 2V, 4V, 6V, 8V, 12V, 24V
Capacity: 0.8AH-24AH
Production technical features: same as the features in the first production workshop

In order to prevent any damage during shipping and delivery, we add the instruction book, the accessories, and two plastic separators in each box.

We deliver over 200 tons of batteries every month.
