Lead-carbon solution


Narada REX-C series batteries are deigned for application of energy storage with patented lead-carbon technology,

combined features of both capacitor and lead acid battery, especially in condition of Partial Status of Charge (PSoC)

• No sulfation problem at negative

• Design life above 20 years (20oC)

• 5~10 times more lifespan at PSoC

• High specific power, fast charging

• About 40% more charge acceptance

Lead sulfate irreversibly accumulated on surface of the

negative plate into a layer, which is dense and coarse

The sulfation can be successfully restrained, as a result,

the charging acceptance and lifespan can be improved


Well-chosen components Lead-carbon technology

AGM separator and active carbon

Patented alloy of grid Innovative safety valve

Pre-disperse and formation



Unique carbon formulation in active

substance of negative, which could

restrain sulfate and improve cyclic life

efficiently under partial SOC status

Special carbon material

Made from ultrafine glass fiber with

high strength, which has excellent

ability in absorbability as well as

maintenance of electrolyte material

Special AGM separator



The carbon materials are evenly

dispersed in aqueous solution with

high speed, that successfully makes

lead and carbon particles mixed

Special pre-disperse tech.

After so many experiments, Narada

found out an exclusive procedure of

formation, that can enhance both the

capacity and cyclic life of batteries

Special formation process


Special carbon formulation Lead-carbon technology

Narada has researched on many materials, such as active carbon, carbon fiber, carbon nanotube, graphene….etc.
