Agricultural field working environments are complex with frequent dust, humidity and bumps. The 12V7Ah sealed lead-acid batteries is optimized specifically for agricultural equipment. Adopting a fully sealed explosion-proof structure, it is leak-proof and corrosion-resistant, adapting to humid fields and high-humidity greenhouse environments, avoiding equipment damage and farmland pollution caused by liquid leakage. With mature internal plate technology, it has strong anti-attenuation ability and long charge-discharge cycle life, resisting bulging and failure after long-term frequent use. Its thickened flame-retardant shell is compression and drop resistant, not easy to be damaged during field movement and backpack operation, providing excellent safety protection for harsh agricultural plant protection scenarios.
