BMW Battery accessory charger like-new with box. Bought this brand new for $180 a few months ago, used it once, then sold the M4 I bought it for. An advanced 8-stage charger that works with 12V lead-acid, AGM and Lithium batteries (including M-model batteries), and can be used on both cars or motorcycles. An amazing tender that works better than the NOCO Genius I had. BMW part no. 61-43-2-408-594.
