Hello and good day Tentoes. Thank you for reaching out and for sharing your experience with us today. It is sad to know that you were not able to fly your DJI Spark for these reasons. Please stay safe always and thank you for your support.
You keep the protective shipping plastic on the charger? There's no need to draw letters on the battery. When they start getting low you just press the button to see if the lights aren't 4 then you know it has been used.

Saving the plastic for Dana Williams.
I marked the batteries so I could be sure I wasn't using and charging one and leaving the others unused.
