Lithium-ion batteries are used in most cordless leaf blowers. They usually operate at voltages between 18 and 120 volts (although some models may be able to handle up to 240 volts). Lithium-ion battery cells are longer-lasting than most other types of batteries with an average life of about 2 or 3 years or 500 charge cycles (depending on the type of cell). They're also lighter than traditional leaf blowers, so they weigh less and are easier to use.
