2V 400Ah Lead Acid Battery

Brand : Yangtze Battery
Product origin : China
Delivery time : Within 10days
Supply capacity : 10000 units/month

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 400Ah 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. Using oxygen recombination technology: maintenance-free

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

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

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