Shopping For an Electric Powered Wheelchair Electric powered wheelchairs can be an excellent aid to those with limited mobility. These chairs are sold at major retailers and specialty mobility equipment providers. Medicare and private insurance could cover the cost of an electric wheelchair if a physician deems it medically required. The majority of power wheelchairs come with a joystick that the user moves to control the motors. The controller, which functions as the brain of the wheelchair converts these movements into electrical signals. Battery Life When looking for a power wheelchair, one of the most important factors to consider is the battery's life. A good battery can last up to two years if it is used regularly and maintained properly. The type of battery determines how far a wheelchair will be able to travel on one charge. Deep cycle batteries are utilized in a majority of power wheelchairs. They offer a long-lasting energy source. These batteries can handle multiple discharges and recharges without causing damage to battery cells. It is important to follow the manufacturer's recommended charge practices. This includes overnight charging of the battery, and avoiding leaving it running at a complete loss. The surface on which the wheelchair operates also influences the battery's lifespan. Smooth, level surfaces require less power to propel the chair, leading to longer battery life. If a wheelchair is used on bumpy or rocky surfaces motors will have to work harder to maintain speed and stability which means that they consume more energy and drains the battery more quickly. The age of a battery and the way it is used can affect its longevity. If a battery is getting old and starting to lose its capacity to hold a charge, it may be time to replace it. electric powered wheelchairs will reduce the time a wheelchair must be charged, and is more likely to have more capacity than older batteries. Wheelchair batteries come in a variety of sizes. The most popular are Group 24 and Group 22NF. Group 22NF batteries are lighter and smaller than Group 24 batteries, which help to reduce the weight and size of the power wheelchair. They have a smaller power reserve or “juice” than Group 24 batteries. Avoid charging or subcharging the battery, as this can reduce its life. Keeping the battery in a dry, cool place is also important because exposure to extreme temperatures could affect the battery's performance. Capacity of Weight Weight capacity is a key aspect to take into account when selecting the right power wheelchair. If the chair is going to be used on long trips, then it must be able to support a user's weight. Overweight can lead to structural problems, decreased battery life, and an increased risk of accidents. The weight of a power chair varies from model to model and is affected by the type of batteries it is powered by. It also is affected by the amount and type of accessories it has, such as oxygen tank holders and various seating systems. However, the majority of its weight is derived from the batteries. One battery can weigh as much as 50 lbs by itself and a powerchair typically has two batteries! The power wheelchair's a two-pole motor or four-pole motor could influence its weight. A four-pole power chair is more efficient, and has a greater weight capacity. However, it will need more energy from the batteries, and can drain faster than a two-pole. Power wheelchairs can also be equipped with different drive bases, like rear-wheel drive or mid-wheel drive. The location of the drive wheels could make a difference in its handling and maneuverability in a variety of conditions. The base of the drive could offer a variety of options, like a swing-away controller that aids in side-transfers, and sip-and-puff controllers that operate by blowing into a sensor. The setting in which a power wheelchair is used is another factor to take into consideration. It is essential that the chair be used on different terrains and can be fitted into hallways and rooms. It is essential to measure the doorways and ensure that the chair is able to pass through them. This includes hinged doors. A physical therapist and/or mobility specialist can assist in selecting the appropriate power wheelchair for your needs. In addition to evaluating the weight of the chair, its speed and range of travel They can also provide advice on other factors such as accessibility, comfort and the size of the seat. They will also look at the frequency and duration of use and whether the chair is likely to be moved frequently. Seating In contrast to manual wheelchairs, electric powered ones are powered by motors that move them. This provides you with more mobility and greater range than a manual chair but it does have some limitations and other aspects that you need to take into consideration. The first step is to know the capacity for weight of your new chair. If it's your own personal weight or the weight of any equipment or items that you're carrying, it is important to not exceed the manufacturer's recommended weight limit to avoid overtaxing the power chair and damaging it. Make sure that the chair you select includes a comfortable footplate as well as an appropriate seat to comfortably fit in. If there isn't enough space for your feet to rest on the footplate, it may shift your center of gravity forward and cause the wheelchair to move. Also, consider a wheelchair that has tilt and recline capabilities to help reduce the risk of pressure sores. This feature is important for those who are elderly and whose skin may be thin and bruises easily. Moreover, power leg rests can help elevate your legs and decrease swelling. Like every mechanical device, will need regular maintenance to function properly and safely. You'll need to examine the battery condition as well as tire pressure, brakes and other parts of the device on a regular basis. You should also examine the seating for wear and make any adjustments that are needed. It is important to store your electric chair in a space that is not exposed to extreme weather conditions. The frame may be damaged by high temperatures, while low temperatures can harm electrical components and the battery. If you don't purchase your wheelchair out-of-pocket, it isn't covered by insurance and you won't have the option to return it if it doesn't satisfy your requirements. Warranty warranties from manufacturers usually last between one and two years and cover the motors electronic, joysticks, and electronics frames but not the back cushions, seats or tires. Before buying an electric wheelchair, inquire with your supplier about the return policy. The most important thing to do is go through the manual and follow the directions for use and maintenance. Operation Power wheelchairs are powered by a motor in the power base that sits under the user's seat. The motor is powered by one or two rechargeable 12-volt batteries in series, giving 24 volts in total. LITH-TECH offers lithium batteries, which are much more energy efficient than lead acid batteries and can be used for longer periods of time. There are a variety of options for customizing the controller, electronics, and power base to meet the needs of every user. For instance, certain chairs offer customizable seating to ensure a comfy fit and let the user choose the best position for the stability of their posture. Many models also come with adjustable height of the seat, recline and leg rest positions as well as power tilt functionality. Electric powered wheelchairs can come with a wide range of additional features. They include oxygen tank holders, elevating chairs and a wide range of power accessories. Certain powerchairs can be customized to allow users to control them with their brainwaves or nerve signals. Some powerchairs have the ability to adjust the speed to the preferences of the user, or to match other vehicles on the road. For instance when driving uphill. They are also equipped with sensors that alert you to dangers or obstacles within the vicinity and automatically slow down or swerve when necessary. The location of the drive wheels, whether they are mid-wheels, rear-wheels or front-wheel drives, has significant impact on how a chair performs under various conditions. This is a huge subject, so we'll save it for a later Clinical Corner. Check that your new electric chair is fully charged and the tires are at the right pressure prior to taking it for an excursion. To get ready for your first time, it's a good idea make some adjustments to your chair, armrests, and footrests. It's important to read the directions in your manual when operating your wheelchair. This is especially important when driving up and down hills. This will reduce the risk of injury, damage or discomfort.
