MBrockman5 Posted April 11, 2019 Share Posted April 11, 2019 Hello all. I just purchased my first bmw bike (07 R1200RT) last week. It came with the factory DWA system, but the unit's internal batteries are dead. I was wondering: 1) Are any CR123a batteries fine to use, or is there a specific recommended brand? I was going to use some SureFire batteries I have Laing around. 2) What is the average lifespan of batteries with this alarm system? Link to comment

Morning MBrockman5 1) Are any CR123a batteries fine to use, or is there a specific recommended brand? I was going to use some SureFire batteries I have Laing around. -- How long have those batteries been laying around? What is the battery life date? I use SureFire batteries in a number of things & they seem to be a decent battery so as long as they are still good with a decent life date left they should work OK. (personally I would buy new & install them if you can gain some life years) 2) What is the average lifespan of batteries with this alarm system? -- Difficult to tell as some go for a number of years & others fail within a couple of years.

lkchris Posted April 11, 2019 Share Posted April 11, 2019 I replaced the batteries on my 2012 RT last summer, having first gotten warning in May. So ... 6 years? BTW, this procedure is nicely detailed in the BMW Service DVD. Link to comment
MBrockman5 Posted April 13, 2019 Author Share Posted April 13, 2019 Ok. Awesome. Thank you for the info. I ended up buying new Energizer lithium batteries just to be safe. Although they fit nice and snug, I did notice that the CR123A batteries are a smidge bigger diameter than the CR17735 batteries that were in it. Link to comment
RedMac Posted May 14, 2019 Share Posted May 14, 2019 I've only replaced the batteries on my 06 once... Which reminds me.. I'm probably due again. I dn't remember.. are there two batteries? or one? (I'm assuming two) Link to comment
MBrockman5 Posted May 17, 2019 Author Share Posted May 17, 2019 There are 2 in the alarm box under the seat. Link to comment
