An intoxalock is a device installed in vehicles that requires the driver to blow into a breathalyzer before the car will start. If the driver has been drinking, the intoxalock will prevent the car from starting. While this is a great safety feature, it can also be frustrating if you find your battery drained after using your intoxalock. There are a few reasons why this may happen:
1) If your vehicle is older, it may not have an alternator that charges the battery while the engine is running. This means that when you use your intoxalock, you are draining power from the battery with no way to replenish it.
2) Intoxalocks require a lot of power to operate. If your battery is already low on power, using an intoxalock can cause it to drain completely.
3) Sometimes, weather conditions can affect how well an intoxalock works. If it's very cold outside, for example, the device may use more power than usual and cause your battery to drain faster.
If you find yourself with a dead battery after using your intoxalock, there are a few things you can do:
1) Charge your battery overnight with a trickle charger or jump start it with jumper cables
2) Have someone else blow into the device for you so you don't have to use as much power
3) Bring your vehicle inside overnight so that cold weather doesn't affect the performance of your intoxication lock
