The most recommended charging frequency for electric wheelchair lithium batteries is: charge once a day, or top up when the charge level is 30%–50%. For lithium batteries, "frequent charging, without waiting until the charge is very low" is the most correct approach.

• 4-wheel rollator: Suitable for people who can walk but are unstable • Manual wheelchair: Suitable for people who cannot walk or stand for extended periods Therefore, the two are not interchangeable, but rather assistive devices suitable for different functional needs.

Compared to traditional lead-acid batteries, lithium batteries have a longer lifespan, typically 2-3 times that of lead-acid batteries. This is one reason why their lifespan data is relatively well-defined. High-quality lithium batteries can typically achieve 800-1200 cycle times, theoretically translating to a daily lifespan of 3-5 years.

For people with insufficient hand strength, arthritis, muscle weakness, or poor balance, mobility scooters can be difficult to control. Therefore, in terms of ease of control, electric wheelchairs are clearly superior to electric mobility scooters.

Considering the characteristics of lithium batteries and practical usage needs, the most reasonable charging range for most electric wheelchair users is usually: 80%–90%

Yes. You can bring a lightweight electric wheelchair on a plane, but you must check the airline's specific regulations in advance and follow the rules regarding lithium batteries, security procedures, check-in procedures, and cargo hold storage.

Carbon fiber electric wheelchairs excel in the following key indicators: • Lighter overall weight • Higher structural strength • Better handling experience • Greater convenience of travel • Better meets the needs of modern users for electric wheelchairs

Electric wheelchairs are important devices for improving freedom of movement, but they do have some issues that cannot be ignored, including: • Reduced battery life leading to shorter range • Heavy weight making them difficult to move • Insufficient adaptability to complex terrain • High maintenance costs etc.

On the first day of the new year, Dahao Medical extends its sincere wishes to its global partners and users: May the new year bring health and prosperity, and may high-quality medical mobility equipment accompany you on every warm journey. Happy New Year!

Electric wheelchairs should not be kept plugged in all the time. Overcharging is not only unhelpful but can also shorten battery life. • The charger should be unplugged when the battery is charged to approximately 90%. • The electric wheelchair battery should not be continuously charged for more than 14 hours.
