We have had 2 days of very cold weather (-22 Celsius, -8 Fahrenheit). The Jag struggles to start. Is this normal, or should I have the battery checked? Granted, my usual commute is very short and perhaps it's not getting a chance to recharge.

If I need to have the battery replaced, are there any special precautions (considering all the electronics)? Is there anything I should prepare for?

Thanks

 

Are you in Canada? If so grab a motomaster eliminator ultra flat panel agm battery from Canadian tire for around $220. Best cold weather battery you can get and it also comes with a 5 year free replacement warranty.
