OPzV Tubular Gel Battery

Technological Merits
1. The OPzV tubular gel battery made from superior materials comes with low self discharge and the monthly self discharge is less than 1.5%.
2. By the adoption of the gel electrolytes, it features large thermal capacity and excellent heat resistant property, suitable for working in the severe environment (-40℃-60℃).
3. The cycling performance and deep discharge recovery capability are very predominant.
4. Without needing moisturizing maintenance, it is designed with a more than 95% gas recombination.
5. Having a long service life and a 20-year floating charge life, this tubular gel battery possesses stable capacity and low attenuation rate during the normal floating charge process.
6. It is an eco-friendly product with splendid sealing performance and without gas permeation or environmental pollution.
7. Famous for distinguished safety, it adopts the professional separator that has high aperture ration and low electric resistance.
8. The copper-made terminal post with low internal resistance ensures a secure cell discharging under the large current without generating heat.
9. The solid gel electrolytes present an evenly-distributed density with no layering phenomenon.
10. As the fireproof and flame retarding safety valve can effectively prevent the external naked flame or spark, the high reliability of product is well guaranteed.

Structural Features
1. Electrolyte
Made from the German aerosol, the electrolyte presents in gel state and does flow inside the finished tubular gel battery. Hence, there is no fluid leakage or layering phenomenon.

2. Plate
The positive plate adopts the tubular plate which availably prevents the coming off of the active materials. The framework of the positive plate is made from the multi-alloy via die-cast formation, featuring excellent corrosion resistance and long working life.

The negative plate is a pasted plate with a special grid structure, thus improving the use ratio of active materials and the cell discharging capability under the large current, and also enhancing the charge acceptance.

3. Cell shell
The shell of the tubular gel battery made from ABS materials features corrosion resistance, high intensity, attractive appearance, high sealing reliability with the cover as well as no leakage possibility.

4. Safety valve
With a special structure and the appropriate pressure for opening or closing, the safety valve reduces the moisture loss and avoids the drying up of the electrolyte as well as the swell and rupture of the shell.

5. Terminal
The built-in lead-based terminal post with copper core possesses large current carrying capacity and high corrosion resistance.
