In order to use your remote, you need batteries. Your remote has a battery pack, and then there is one or two batteries that sit in each car that also needs a battery pack. If you have a remote for 6 cars, for example, then you will need six of the smaller size installed, but have 10 batteries left over! This means everyone can just grab one of the extra batteries and use it on the 7th car when the time comes.

The type of battery your alarm key has depends on the size of batteries that come with it. Usually, an AAA battery will power a wireless key fob that is 30-40 feet away. However, if you have a remote that is 70-80 feet away instead of using an AAA you can use a CR1632 3V coin cell battery.

Power vs. Capacity: What’s the Difference?

Key fobs with power come equipped with a built-in battery that can last up to three years before needing a replacement. Removing the key fob when it’s empty will drain the batteries power, which leads to them shrinking in size.

A battery (or other power source) stores electricity. To give you a comparison point, think of a water pump that can create two gallons of water per minute, but has to be switched off for 40 minutes between each use to allow enough time for the pump to recharge. What type of batteries are more energy-efficient than the other? A battery that’s able to switch its power on quickly and set lots of small pumps working at the same time is more efficient than one that takes forever to charge and requires lots of shut offs.

Power is measured in watt-hours where capacity is measured in amp-hours. Amps nominally mean ampere which is the SI unit of charge and amps are used as a measure of electrical load. Your battery will have a certain amount of power and it will also have a certain capacity. Generally speaking, the higher the power, the more you can run your devices such as a key fob for about an hour. However, if you need to run your device for longer than one hour then you should look into ensuring that you purchase a larger battery with higher capacity.
