Lead-acid batteries are the most commonly used type of battery for portable generators. The batteries are affordable and can provide enough power to start a generator's engine. However, they are heavy and require frequent maintenance to ensure a long service life.
Lithium-ion batteries, due to their lightweight design and high energy density, lithium-ion batteries are becoming increasingly popular. They require less maintenance than lead-acid batteries and last longer. However, they are more expensive than lead-acid batteries. Most batteries can be generated at high capacity and high power, and for a 2kw generator, lithium-ion batteries can provide a lot of power with a light weight. Therefore, a 2 kW generator is the most recommended capacity for lithium ions.
Nickel-cadmium batteryCompared with lead-acid batteries, nickel-cadmium batteries are less used in portable generators because of their lower energy density and higher cost. They are also heavier than lithium-ion batteries. However, they live longer and can withstand extreme temperatures.
When choosing a battery for a portable generator, consider the required voltage and capacity, the weight and size of the battery, as well as cost and maintenance requirements. By understanding the different types of batteries available, you can choose the best battery for your portable generator needs.
