Understanding Car Key Fob Batteries
Car key fob batteries are typically small, coin-sized cells that provide power to the device. They are designed to be compact and lightweight, making them easy to install and replace. The most common types of batteries used in car key fobs are alkaline, nickel-cadmium (Ni-Cd), and lithium-ion (Li-ion).
Alkaline batteries are the most widely used type, offering a balance of power and longevity. They are inexpensive and widely available, making them a popular choice for many car owners. However, they have a limited lifespan and may not provide the same level of performance as other types of batteries.
Ni-Cd batteries, on the other hand, are known for their high capacity and long lifespan. They are a good option for car owners who want a battery that will last longer than an alkaline battery. However, they contain toxic materials and should be disposed of properly to avoid environmental harm.
Li-ion batteries are the latest technology in car key fob batteries. They offer high power density, long lifespan, and are environmentally friendly. They are also more expensive than alkaline batteries, but provide a superior performance.
What Size Battery Do I Need?
The size of the battery you need will depend on the type of car key fob you have. The most common sizes are CR2032, CR2450, and CR2032. (See Also: How Long Until Car Battery Goes Flat? – The Ultimate Guide)
CR2032 batteries are the most widely used size, measuring 20mm in diameter and 3.2mm in thickness. They are commonly used in standard key fobs and are available in alkaline, Ni-Cd, and Li-ion varieties.
CR2450 batteries are slightly larger than CR2032 batteries, measuring 24.5mm in diameter and 5mm in thickness. They are used in larger key fobs and are often used in high-end vehicles.
CR2032 batteries are the smallest of the three, measuring 20mm in diameter and 3.2mm in thickness. They are used in small key fobs and are often used in older vehicles.
