My second generation CX5 (2017) with istop has completed 3 years and I am getting worried about the life of the original battery. It is charged/topped up now and then using a C-Tek charger and I have recently topped up both the charge and the distill water in the battery. Winters are harsh here in Sweden and all the electronics plus stop start takes its toll on the battery. As I gather from reading at this site and other sources, our batteries are regular flooded lead acid optimised for start stop and made by Panasonic with about 540CCA. Now to my question.
1. Do I have to go to the dealer to replace the battery or can I use equivalent flooded battery and replace it my self as I have done in my other cars?
2. Is the battery management system (what ever it is called in Mazda language) going to cause problem (istop feature, power windows and other gremlins) with DIY battery replacement?
3. Does the new battery need to be registered/reprogrammed for optimal charging and other features (like my old BMW E90 did), making an expensive visit to the dealer mandatory.
4. How many of you with istop feature have done a DIY battery replacement without getting in to issues in your CX5? What battery did you use?
Finally, I found an article from a Russian site which is very detailed in information on our CX5 battery and its replacement. The only problem is the rather dodgy English translation in some parts. There are two things in that article that struck me as unusual, he suggests disconnecting the negative terminal sensor (I presume it is the little black box like thing on the cable going to the negative terminal) before disconnecting the negative terminal itself and the other fact that within i minute of disconnection of the battery the management system resets itself to charge a new replaced battery). I never heard of that anywhere else. Here is the link.
Grateful for comments and advice.
