Battery change in Polar G3 GPS sensor W.I.N.D and Polar G1 GPS sensor

You can change the battery yourself to G1 GPS sensor and G3 GPS sensor W.I.N.D.

Use an AA-sized alkaline battery. We recommend you to use a lithium battery or rechargeable NiMH battery in temperatures 5°C and below. Cold temperature decreases the life of an alkaline battery.
