# Batteryless
The Lithium batteries in Eons cannot handle the heat of being in a windshield. They can expand and even explode if left in the summer heat. They also, of course, wear out.
The Lithium batteries in Eons cannot handle the heat of being left in an un-cooled windshield. They can expand and even explode if left in the summer heat. They also, of course, wear out.
### Problems:
1. The Eon needs to know it has a battery to even try to boot.\
The internal software of the phone needs to see that a battery exists. In the case of a OnePlus3T, it just needs to see a voltage between 4.35 and 2.9V from the battery wire.

#### Note: Supercapacitors require charging. But unlike with batteries, they will try to pull as much current as possible from the charging source. The more charged they are, the less current they will try to draw. This means that completely uncharged supercapacitors will look like a short-circuit to any monitoring electronics. However, once they're partially full, they'll be kinder to the charger. The OnePlus3T seems to handle this situation well without modification.
