Charging deeply discharged battery (Caretta)

If Caretta does not start up after pressing and holding the power button for 6 seconds, the internal battery is completely depleted.

Under normal circumstances, simply connecting a suitable USB charger to the USB-C port will automatically boot Caretta and begin charging.

Restoring a Deeply Discharged Battery

If the battery is deeply discharged, the remaining voltage may be too low for the internal charging circuitry to initialize charging automatically.

To restore charging:

1. Connect Caretta to a USB power source.
2. Wait 30 seconds (do not press any buttons during this time).
3. Press the power button once.

Caretta will initialize its charging sequence. Initially, you will see a black screen displaying a battery charging symbol. Once the battery reaches a sufficient charge level, you can power on the system as usual.
