It will take its toll over time on your battery. I have alot of play vehicles that sit and have learned 15 years ago I can make a battery last 4x longer in years by using a tender all the time than letting them discharge over and over again. From boats,Harley's, atv's, tractors, cars, etc.. I dont replace batteries hardly ever now.
The parasitic loss on these modern BMW's and their sensitivity to power just makes them far more susceptible to battery issues. Every BMW in my dealers showroom is on a tender. That should tell you alot.
This one is on both my new BMW's and its strong enough to charge the batteries after extended times the doors/radio is open.
Battery Tender 022-0209-DL-WH 4Amp Selectable Charger is an AGM/Standard or GEL/Lithium Iron Switchable, 12v or 6v Switchable at 4a, Includes Rings & Clips. It Will Never Over Charge Your Battery

Do you select for AGM or Li Ion ?
