Battery care and safety

What the battery management system protects against: Over charge protection, Over discharge protection, Over current protection, Short current protection, Balanced function, Temperature protection.
Temperatures it may be charged in: 0°C to 45°C (32F to 113F) at 60±25% Relative Humidity
Temperatures it may be run in: -20°C to 60°C (-4F to 140F) at 60±25% Relative Humidity
Temperatures it may be stored in: 0°C to 40°C (32F to 104F) 60±25% Relative Humidity
Using a cranking battery: Note that these batteries are not suitable for starting internal combustion engines – the current requirement for this application is much higher than the capability of the 12V General Purpose range.
