8 - First things first Guidelines for safe battery usage Warning When using a charging cart or a small space to simultaneously charge or operate multiple devices , the area must be wellventilated and the temperature kept between 0 °C (32 °F) to 35 °C (95 °F) and battery charging must be stopped when 100% capacity is reached.
