Product Details

OPzV 2-420-Y of Rechargeable Tubular GEL Battery

A sealing system of tube type GEL lead-acid battery terminal, terminal, the main lead battery comprises a battery cover, a battery cover set terminal slot, the lower terminal slot for terminal, terminal terminal port through the lead of the top and a copper connection terminal block injection together, lead terminal in the terminal opening is arranged on the ring boss, snap ring from the ring boss provided with type sealing ring groove ring, pressure sleeve, lead terminal and the card in the annular groove of the terminal port, and pressure matched, a rubber washer is arranged between the pressure sleeve and the terminal mouth, filling gaps in the terminal slot the injection of polar sealant.

Product Feature & Material Advantage of Rechargeable Tubular GEL Battery

1. Plates:1% higher than the average content of tin plate, effectively prevent corrosion and sulfide of the plate.

2. Positive plate: Tubular type, with die-casting thick Pb-Ca grid; it has very good corrosion resistance

and a very long service life

3. Paper separator: using domestic top brands, a variety of materials certification.

4. Safety valves: Good sensitivity, safe and reliable, equipped with double flame arrester/acid filter

5. Terminals: All copper materials, there are many other battery suppliers using lead terminals.

6. Battery case: Made of high strength ABS and durable design

7. Battery products: enough plate number, enough battery capacity, enough weight.

8. Separator: PVC-SiO2 separator imported from Europe, low internal resistance, high pore rate and

 long life;

9. Negative plate: Pasted flat type, radial grid design, good high rate discharge performance

10. Electrolyte: Silicon-containing salt composition, effectively prevent the battery from dehydration.

11. Flooded electrolyte design: Contain more electrolyte like a flooded battery, pace between plates and separators is full of electrolyte thus means good heating capacity and avoid ‘thermal runaway’
