Rechargeable wheelchair batteries come in three types: wet cell, gel, and AGM. They are interchangeable between chairs and brands, but require specific chargers. Gel and AGM batteries are less prone to leaking and can be left attached to an electric wheelchair during air travel. Additional chargers and a travel charger are useful accessories to have. […]
Laptop batteries are essential for mobility and have evolved to be more durable and functional, with lithium-ion batteries being the most common. Previous technologies had problems with memory effect and losing the ability to recharge. Laptop batteries need to be replaced eventually, with heavy use requiring replacement almost every year. Fast-charging batteries are a new […]
Li-Polymer batteries are thin, lightweight, and rechargeable, commonly used in electronic devices. They are a safer alternative to lithium-ion batteries and are less flammable. LiPoly batteries are lighter in weight and ideal for laptops, cell phones, and digital cameras. To increase battery life, dim the screen, avoid multitasking, keep it clean, and cool. Zinc-based batteries […]
Flywheels store energy in large wheels sealed in a vacuum, used to store and release electrical energy. They have a mechanical method of storage, making the amount of energy stored limited only by the size of the flywheel. Flywheels are supported by magnetic bearings, making them cheap, reliable, and requiring little maintenance. They have virtually […]
Batteries work through redox reactions, transferring electrons between an oxidizer and a reducer to create a direct current. Manganese dioxide and zinc are commonly used as oxidizers and reducers, respectively. Batteries have not substantially changed since their invention. Batteries, or dry cells, work by connecting, through a circuit, a material that wants to donate electrons […]
