My 2015 R1200RT has had 4 batteries (OEM, Yuasa, OEM, Interstate) in its short (36K miles) life, the newest being an "Interstate" battery meant for an ATV. It was the only thing available where I was when my second BMW OEM battery died while on a trip to Angel Fire, NM. Yesterday, after returning home and parking the bike in its stable, I immediately plugged in the BMW OEM Battery Charger whereupon the display (after recognizing that it was now attached to the battery through the front socket) immediately showed a voltage of 14.7 volts.
My question....is the bike's charging system overcharging the battery and is that why I've had to replace them so often? Currently, the charger shows Full at 14.0 Volts with a trickle charge of 0.2A.....
