NiMH batteries offer a lighter alternative to lead-acid batteries and hold more energy per unit weight. This type of battery provides a good balance between performance and price, making them a popular choice for many electric wheelchair users. NiMH batteries have a lower discharge rate and can perform better in colder temperatures. They are also more environmentally friendly, as they contain no toxic metals like cadmium or lead. However, NiMH batteries can self-discharge faster compared to lead-acid batteries, which means they may require more frequent charging if not used regularly.

In addition to efficiency, medical carts also enhance safety and organization. Most modern medical carts are designed with safety features such as locking drawers, which secure medications and sensitive materials away from unauthorized access. This is particularly important in preventing medication errors and ensuring compliance with safety regulations. Moreover, many carts are color-coded or labeled, facilitating easy identification of supplies and reducing the likelihood of confusion during fast-paced situations.
