My son has a 2002 M Coupe which is going to spend most of the school year under a cover in our driveway. I plan to drive it once a week or so to give it some "exercise". One knowledgeable person suggested I put a battery tender on it.
BMW makes one, but it appears to go into the cigarette lighter. I presume there's no path from outside the car to the cigarette lighter without leaving a window open. I see that there are other battery tenders that attach to the battery. That'll be a bit a pain to disconnect and reconnect once a week.
Any suggestions? Will a non-BMW battery tender do any harm?
Thanks,
Matthew
Battery tender suggestion?
BMW battery tenders now have battery clips. cigarette lighter versions are pretty much useless especially with newer beemers becuase the power supply goes away when vehicles assume full sleep.
I use my BMW tender under the hood on my 1M all the time. very easy to use.
Of course the company that makes BMW charger is the same at this website www.batterytender.com

More than once this cheap $10 one from HF has been recommended to me:

I also recommend the Battery Tender brand. I have 3 and they are at least 9 years old and all work perfectly. They have been dropped, rained on and one was even partially run over and they all work great. You might be able to find cheaper ones but when I am traveling and that is plugged in alone in the garage I never worry about coming home and something being burned out or shorted. Piece of mind is priceless
