I have the BMW alarm and tracker on my bike.
I have no alarm on my 1250 but just the tracker! Never wanted it in the first place. Subscription expired at the 12 month point. Original battery failed at the 14 month point and was replaced by me dealer with a Yuasa. That was as flat as a pancake this morning. Took the bike apart and found the tracker to remove it. It is rated as 12v 2 amp.
Battery now being sorted and hopefully will have no more problems.
