The 32700 (32650) battery is a lithium-ion battery. The "32" in the model number represents a diameter of 32mm, the "70" represents a length of 70mm,
and the "0" indicates it is a cylindrical battery. This type of battery typically uses lithium iron phosphate (LiFePO4) as the cathode material,
which offers high energy density, long cycle life, safety, and reliability. Compared to traditional lead-acid batteries and nickel-cadmium batteries,
32650 batteries offer significant advantages in performance.
Why do solar lights prefer 32650 batteries?
High Energy Density: The energy density of the 32700 (32650) battery is much higher than that of traditional batteries,
meaning it can store more electrical energy in the same volume. This feature is crucial for solar lights, as they need to convert solar energy absorbed during
the day into electrical energy and store it for night-time lighting.
Long Cycle Life: 32700 (32650) batteries generally have a long cycle life, reaching thousands or even tens of thousands
of charge and discharge cycles. This is essential for solar lights, as they need to be used outdoors for extended periods and endure
harsh environmental conditions like wind, rain, and sun. A long cycle life means the battery can withstand more charge and discharge cycles, prolonging the life of the solar light.
Safe and Reliable: 32700 (32650) batteries have excellent safety performance and are less prone to dangerous situations like explosion or fire.
This is due to the use of lithium iron phosphate, which remains stable under high temperatures or overcharging and is less likely to cause safety incidents.
Additionally, the 32650 battery is equipped with various safety protection mechanisms, such as overcharge protection, over-discharge protection, and short-circuit protection,
further ensuring safety and reliability during use.
