Shopping For an Electric Powered Wheelchair An electric powered wheelchair can be extremely beneficial for those with limited mobility. These chairs are sold at major retailers as well as specialist mobility equipment suppliers. Medicare and private insurance could pay for the cost of an electrical wheelchair if a doctor deems it medically essential. Most power wheelchairs have an electronic joystick that the user uses to direct the motors. These movements are converted to electrical signals by a controller that functions as a brain for the chair. Battery Life Battery life is an important aspect to take into consideration when purchasing wheelchairs. A good battery can last for up to two years if used regularly and regular maintenance. The type of battery can also influence the distance a wheelchair can travel on a single charge. Deep cycle batteries are utilized in most power wheelchairs. They provide a long-lasting energy source. These batteries can handle multiple discharges and recharges without causing damage battery cells. It is essential to follow the manufacturer's recommended charging practices that typically include overnight charging of the battery and avoiding allowing it to run completely empty. The surface on which the wheelchair is operated also influences the battery's lifespan. Smooth smooth, level surfaces require less power to propel the wheelchair, which results in a longer battery longevity than rough terrains. If a wheelchair is driven over rough terrain, the motors will have to work harder to maintain speed and balance which consumes energy and drains batteries faster. The age of a battery as well as its usage pattern can also affect its longevity. It is possible to replace batteries if they are becoming old and losing its capacity to keep charge. A newer battery will decrease the time required to charge a wheelchair and will likely to be more powerful. Wheelchair batteries come in various sizes. The most popular are Group 24 and Group 22NF. The Group 22NF batteries weigh less and are smaller than the Group 24 batteries. This helps reduce the overall weight and size of the wheelchair. However, these batteries have lower power or “juice” reserve than Group 24 batteries. It is recommended to avoid charging too much or undercharging the battery, as this can cause it to shorten its lifespan. Keeping the battery in a dry, cool place is also important because exposure to extreme temperatures can negatively impact the battery's functionality. Capacity of Weight The weight capacity is an important aspect to consider when choosing the best power wheelchair. If the chair is going to be used for long-distance trips, then it must be able to support a user's weight. Weight issues can be caused by excessive weight, which could lead to problems with battery life and accidents. A power wheelchair's weight varies from model to model, and is affected by the type of batteries it uses. The weight of a wheelchair is also affected by the number of accessories and the type of accessories, such as oxygen tanks holders as well as different seating systems. The batteries account for the majority of the weight. One battery can weigh as much as 50 lbs by itself and a power chair usually has two of them! The weight of a power wheelchair can also be affected by the type of engine it is an engine with four poles or two. A four-pole motor is more efficient and has a higher capacity for weight. It will however require more energy and drain the batteries faster than a motor with just two poles. Power wheelchairs can also have different base drives, such as rear-wheel drive or mid-wheel drive. The location of the wheels may affect its handling and maneuverability in different conditions. The base of the drive could include a range of options, including a swing-away controller which aids in side-transfers, and sip-and-puff controllers which work by blowing on the sensor. The environment where a power chair is used is a different 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 make sure that the chair can fit through them. This includes hinged doors. A physical therapist or mobility specialist can help you select the best power chair for your needs. They can provide advice on aspects such as comfort, accessibility adjustments, seat size, and the weight of the chair. They will also look at the frequency and duration of use and whether the chair will be moved frequently. Seating Electric wheelchairs are powered by motors to move them, in contrast to manual wheelchairs. This allows you to move more freely and farther than a manual one, however, there are a few limitations. The first step is to know the capacity of your new power chair. You shouldn't exceed the recommended weight limit, whether it's you or any equipment or other items that you're carrying. Make sure that the power chair you choose includes a comfortable footplate as well as an armchair that you can fit in. If your feet don't fit onto the footplate of the chair, your center gravity can be moved backwards, and the chair will slouch. Choose a chair that has tilt and reclining functions to lower the chance of developing pressure sores. This feature is crucial for those who are older, as their skin can be thin and bruise easily. Moreover, power leg rests can help elevate your legs and decrease swelling. Like every mechanical device, requires regular maintenance in order to operate properly and safely. You'll need to check the condition of your battery as well as brakes, tire pressure and other parts of the device frequently. Also, you should check the seat for wear and make any necessary adjustments. You should also pay attention to where you store your power wheelchair so that you don't expose it to extreme weather conditions. The frame may be damaged by high temperatures, and low temperatures can harm electrical components and the battery. If you don't purchase your wheelchair from the pocket, you won't have insurance coverage and won't be able to return it if you discover that it doesn't meet your requirements. Manufacturers' warranties usually last between one and two years. They include joysticks, motors frames, and electronic components, but not seats, back cushions or tires. Before buying an electric wheelchair, inquire with your dealer about their return policy. The most important thing is to read the manual thoroughly and follow the instructions regarding use and maintenance. Operation Power wheelchairs are powered by a motor within the base of power that is located beneath the user's seat. The motor is powered by rechargeable batteries that are 12 volts connected in series, for total voltage of 24 volts. LITH-TECH's lithium batteries are more energy efficient than lead acids and can be used for a longer period of time. Many options are available to customize the controller, electronics and power base to meet the requirements of each user. For instance, some chairs can be customized to help ensure a comfortable fit and allow the user to find a position that best supports the stability of their posture. Many models include adjustable features, such as leg rest, seat height and recline positions, as well as power tilt functionality. There are many additional extras offered for electric powered wheelchairs, including oxygen tank holders elevating seats, and a variety of power accessories. Certain powerchairs can be customized so that the user can control them using their brainwaves or nerve signal. Certain powerchairs have the capability to adjust their speed to suit the user's preference or to match the speed of other vehicles on the road, such as when driving up hills. Certain powerchairs come with sensors that warn them of dangers or obstacles close by, and they automatically slow down and swerve when necessary. The positioning of the drive wheels – whether they're rear-wheel, mid-wheel or front-wheel drive – can have a huge impact on how the chair performs under various situations. This is a massive issue, so we'll leave it for a later Clinical Corner. Check that your new electric chair is fully charged and the tires are inflated to the correct pressure prior to going for an outing. It's also recommended to make a few adjustments to the seat, armrests, footrests (if necessary) and joystick, to prepare it for its first use. It's important to read the directions in the manual before operating your wheelchair. ultra lightweight electric wheelchair is especially important when driving on and down hills. This reduces the chance of discomfort and injuries.
