MOQ :

As a big battery manufacturers in China, we supply many different kinds of batteries , such as the lead acid AGM battery , Gel battery , AGM deep cycle battery , Gel deep cycle battery , OPzV Tubular battery , OPzS Tubular battery ..etc .

The following is our 2V 2500Ah Lead Acid Battery features :

1. Special grid alloy and high purity raw material ensure less gassing, less self-discharging

2. Grid refining technology and the thicker plates are used to extend the battery standby life and reduce
the plate grid corrosion speed

3. Lower acid density, excess of electrolyte and larger distance between plates to keep battery at low temperature and slow down plate grid corrosion speed

4. ABS material: increase the strength of battery container. (Flame-retardant ABS is optional)

5. Using oxygen recombination technology: maintenance-free

6. Unique vent valve design: control water losing, prevent air and spark going inside
