Many parents who are considering the purchase of the Amber Alert GPS tracking system for their children inevitably ask how the units are powered. They also want to know how long the battery life is on the units that their children will be carrying with them. Some child locator devices use regular store bought batteries but not the Amber Alert. These GPS tracking devices come with a rechargeable battery to power the unit.
The battery life of these batteries is a very respectable 18 – 24 hours which is enough to more than cover the average day of your child from the moment they leave your home to the moment they are safely back. The variable in the battery life is whether or not you choose to use stand by mode or the “real time” feature, which is constantly storing a last point. This is essential if your child leaves an area that is covered by a GPS so that you have a last known whereabouts. This constant updating does use the battery faster but having a last known location can be extremely useful so parents will need to decide which is more important to them. Though for many the choice is simple the real time updates do no take up enough battery life to be hardly noticeable.
