Understanding Car Key Fob Batteries
A car key fob battery is a small, rechargeable battery that powers the remote control functions of your vehicle’s keyless entry system. It is typically located inside the key fob and is responsible for transmitting signals to the vehicle’s receiver, allowing you to lock, unlock, and start the engine without having to physically insert the key.
Car key fob batteries come in different types, including alkaline, nickel-cadmium (Ni-Cd), nickel-metal hydride (NiMH), and lithium-ion (Li-ion). Each type has its own set of characteristics, advantages, and disadvantages, which we will discuss in more detail below.
Types of Car Key Fob Batteries
| Type | Description | Advantages | Disadvantages |
|---|---|---|---|
| Alkaline | A non-rechargeable battery that uses a chemical reaction to generate electricity. | Inexpensive, widely available | Short lifespan, environmental concerns |
| Ni-Cd | A rechargeable battery that uses nickel and cadmium to generate electricity. | Long lifespan, cost-effective | Toxic materials, memory effect |
| NiMH | A rechargeable battery that uses nickel, metal hydride, and hydrogen to generate electricity. | Long lifespan, environmentally friendly | Higher cost, self-discharge |
| Li-ion | A rechargeable battery that uses lithium, cobalt, and oxygen to generate electricity. | High energy density, long lifespan, environmentally friendly | Higher cost, potential safety concerns |
