Solar battery is the application of 'battery' in solar photovoltaic power generation. There are four types of lead-acid maintenance-free batteries, ordinary lead-acid batteries, gel batteries and alkaline nickel-cadmium batteries. GEM Battery solar batteries are mainly: lead-acid maintenance-free batteries and gel batteries, GM GzV GzS three types of batteries, because of their inherent "maintenance-free" characteristics and less pollution to the environment, they are very suitable for reliable solar energy Power systems, especially unattended workstations.
