Scooter and Wheelchair Battery, Lithium or Lead-acid

Lithium Battery or Lead-acid Battery

Wheelchairs or mobility scooters are important to the user and are an indispensable tool in their daily lives. Because of this, the purchase of a wheelchair or mobility scooter is carefully considered, and the purchaser expects the wheelchair to have a long service life. The service life of the wheelchair or mobility scooter is affected by a variety of factors, the battery is one of the more important factors, and the service life of the battery largely determines the service life of the electric vehicle. So, do you understand power wheelchair and mobility scooters' batteries? If you don't know, it doesn't matter, I'll introduce you to two kinds of power wheelchairs and mobility scooter's batteries, which are also two kinds of batteries commonly used by wheelchairs and mobility scooters.

Lithium Battery

Lithium battery is a type of battery that uses a non-aqueous electrolyte solution made of lithium metal or lithium alloy as a positive or negative electrode material. In 1912, lithium metal batteries were first proposed and studied by Gilbert N. Lewis. It has the following characteristics.

1, the energy is relatively high. With a high storage energy density, it has now reached 460-600Wh/kg, which is about 6-7 times that of lead-acid batteries.
2, long service life, service life can reach more than 6 years, lithium ferrous phosphate is the positive electrode of the battery 1C (100% DOD) charge and discharge, there is a record that can be used 10,000 times.
3, the self-discharge rate is very low, which is one of the most prominent advantages of the battery, generally can be less than 1% / month, less than 1/20 of the nickel-metal hydride battery.
4, light weight, the same volume of weight is about 1/6-1/5 of lead-acid products
5, high and low temperature adaptability, can be used in the environment of -20 °C --60 °C, after process treatment, can be used in -45 °C environment.

Lead-acid Battery

Lead-acid battery is a battery with electrodes made mainly of lead and its oxides, and the electrolyte is a sulfuric acid solution. French Plant in 1859 invented lead-acid batteries, has experienced nearly 150 years of development, lead-acid batteries in theoretical research, product types and varieties, product electrical properties and other aspects have made great progress, the scope of application is very wide.

1. The electromotive force is relatively stable and the working voltage is stable during discharge.
2, the use of temperature and the use of wide range of current.
3. Good storage performance (especially suitable for dry charge storage).
4, the cost is low.

The disadvantage is that it is smaller than energy (energy stored per unit weight), very bulky, corrosive to the environment, short cycle service life, large self-discharge, and not easy to discharge.

In summary, we can conclude that lithium batteries are superior to lead-acid batteries in terms of performance and environmental protection. However, the development history of lead-acid batteries is longer than that of lithium batteries, and the manufacturing process and usage are more mature. On top of that, lead-acid batteries are cheap. Through the above introduction, you should have a general understanding of power wheelchair and mobility scooter's battery. Hopefully, this will help you better understand your power wheelchair and mobility scooter or in purchasing.
