IMPORTANT: How to preserve the STM32 Primer batteries..

The batteries charging circuit is quite simple, and charging them during a long time can produce heat and reduce their life time.

To preserve the batteries:
1. You have to AVOID PERMANENT USB CONNECTIONS !!
2. When programming-debugging, we STRONGLY RECOMMEND to DISCONNECT THE BATTERY by removing the jumper.
3. Respect the charging time (around 10 hours).
