May be your Tracker is draining too much battery . I have Civic 9 generation and it remain parked too for weeks even months. I only drove it for 13000 km in two and a half year. My first factory fitted battery lasted around two complete years and it get dried as i didn't check its water level in two years (my bad). It never gives me any problem even if i start my car after a month. The longest period was i started my car after two months as i was away from home. When i replaced my battery after getting dried , i got the problem that you described. I replaced it in company workshop. After remain idle for only 10 days , i started my car but battery was dead. I recharged it , used my car for a day and then parked it for a week. After a week ,car battery was again dead. I sorted out the problem and problem was.
- Company didn't fit New battery. Its manufacturing date was 9 month old and it was not freshly prepared.
- Company recharged it once in a month to make it in a working condition and recharged battery is good for daily running cars but not good for cars which remain parked for weeks
I replaced my car battery in warranty and got freshly prepared one with manufacturing date not exceeding two months. Now i am not facing any problem, still park my car for weeks but making my habit to start the car at least for 10 min in two weeks.
