            With the development of science and technology, portable electric wheelchairs have become more and more portable, thanks to the development of materials industry and battery industry. Friends who buy portable electric wheelchairs generally focus on electric wheelchairs equipped with lithium batteries. How long can an electric wheelchair using a lithium battery last?

            Compared with the traditional lead-acid battery electric wheelchair, the lithium battery portable electric wheelchair is much lighter in weight. The general lithium battery electric wheelchair can be folded, so it is very convenient to carry. The traditional lead-acid electric wheelchairs weigh 70 to 80 kilograms lightly and weigh one to two hundred kilograms. The lithium battery electric wheelchair is generally only more than twenty kilograms, so it is very convenient and easy to use.
 
            Many people want to know how long the portable electric wheelchair lithium battery can be used. Everyone knows that consumables generally have a useful life. Therefore, the battery of the electric wheelchair is the same whether it is a lead-acid battery or a lithium battery. Therefore, these power storage capabilities will gradually decline with the passage of time. The service life of the battery is generally calculated according to the number of charge and discharge cycles. The cycle charge and discharge times of lead-acid batteries are about 300-500 times, and the cycle charge and discharge times of lithium batteries are about 800 times. Therefore, the service life of normal use lithium batteries will be longer than lead-acid batteries. This is one of the main reasons why lithium batteries of the same capacity are more expensive than lead-acid batteries.

            The range of portable electric wheelchair lithium battery generally depends on the motor power of the electric wheelchair, its output power control, and electric wheelchair. Generally, the size of the lithium battery capacity. For a lithium battery of the same capacity, the greater the motor power, the greater the control output power and the shorter the cruising range, and vice versa.
