Using it is very easy. Drop the Battery Heater between the battery box and battery. Connect the plug-in to the cable of the car engine or interior heater. That's all. If necessary, secure the heater around the battery with quick-lock belts. Quick-lock belts are included in the product package.
The heater has a great amount of power despite its low power consumption of just 57 watts. When you switch on the battery heater in the evening, the battery is guaranteed to be warm in the morning and your car or machine will start without trouble.
The heater is equipped with a thermostat which optimises the temperature of the battery fluid and cells, maintaining it at 20±5° C. The thermostat has been integrated to the heater itself, therefore also keeping the surface temperature of the battery within safe limits.
The battery heater complies with the requirements of the SFS-EN 50066 standard and Low Voltage Directive.
The product is also patent and design protected.
Why do batteries lose power during cold weather?
In cold temperatures, the chemical reactions inside the battery cannot take place properly which causes the internal resistance of the battery to increase and voltage to drop. A cold battery provides very little power. It also cannot charge properly or at all.
Even if the battery was charged fully in a warm garage, at -18°C, the battery will only provide 50% of its power. If the battery is a little bit old and used for driving short distances, it is never completely full. In such cases, there is a high risk that the car will no longer start.
