My 18 month old Mazda's battery was totally dead on my return from holiday. Mazda dealership say this is to be expected when the car hasn't be used for 4 weeks. Was advised to take off earth lead and attach trickle charger. Also told that the battery would not start to take charge for the first 6 hours. I left it on for 28 hours and things now seem back to normal. Anyone with the same experience? Just as well the car was at home as I would have been very annoyed if I'd used it to the airport.
If this is the norm then is there anyway to stop the total discharge? Sure I could remove the earth connection but then the alarm would be knocked out. Would a small solar panel generate enough of a charge?

 

I was riding in the back seat, behind driver, of my wife's mazda 6 one nite and noticed the GLOVEBOX light was on. Could BARELY see it through the top of the lid but its ALWAYS ON !!. I pulled the bulb.Mazda 6 batterys go fast ive noticed on the thread here, weve put oen in a few years ago so maybe i saved ours.NO telling what else is still running while the keys is OFF!!!

 

I have 4th battery on mazda6 around 60,000 miles. This is very normal for mazda6.

Thanks for the replies. From what I can see there are no lights remaining on. Seems to be simply a matter of too much going on in the electrical system whilst the car us unused. Thinking now of fitting a battery brain but need to check if the car's immobilzer will be a problem.
