What Kind Of Battery Does A Nissan Altima Key Fob Use

How to replace battery in Nissan key fob

This is a question that we get a lot here at the Nissan Altima key fob battery replacement center. To be honest, it is a bit of a trick question. The Nissan Altima key fob doesnt use a battery. It uses a capacitor.

A capacitor is a device that stores electrical energy in an electric field. It is similar to a battery in that it can store a charge and release it when needed. However, a capacitor can store and release energy much faster than a battery. This makes it ideal for use in devices that need to release a large amount of energy quickly, such as a key fob.

The downside of using a capacitor is that it can only store a limited amount of energy. This means that the key fob will eventually need to be recharged. The good news is that recharging a capacitor is much faster and easier than recharging a battery. All you need to do is place the key fob in the charger for a few minutes.

So, there you have it. The answer to the question, What kind of battery does a Nissan Altima key fob use? is that it uses a capacitor.
