Batteries: Operating Principles 4.4.1
Charging / first-time use
• The battery must be charged prior to using it for the first time because it is delivered with an energy content as low as possible
• The permissible temperature range for charging is from 0 °C to +40 °C/ +32 °F to +104 °F. For optimal charging, we recommend charging the batteries at temperature of +10 °C to +20 °C/+50 °F to +68 °F
