Which is better, deer battery or Fu Nan battery?

1, Shuanglu battery: Shuanglu battery is made of graphite and high-efficiency conductive steel, which improves the conductivity of the battery. Shuanglu battery adopts double protection technology, new sealing ring and leak-proof technology, which has good leak-proof and explosion-proof performance.

2. Fu Nan battery: Fu Nan battery has been in the first echelon of the industry since its first generation, constantly pursuing higher battery capacity. Fu Nan battery has greatly improved the conductivity of the battery through the exclusive research and development of high-energy positive ring fused with precision graphite. Fu Nan battery adopts brand-new anti-aging sealing ring, anti-corrosion nickel-plated fine steel shell, upgraded leak-proof and explosion-proof formula, strict leak-proof and explosion-proof detection, and quadruple protection technology to make the battery safer and more secure.
