Zitat von Ray B im Beitrag #15
You're list of usual reasons likely accounts for some of the problems, but I'll reiterate a theory based on my experience, as it seems a large number of veteran riders and mechanics are running into early failures.

My OE battery was damaged by recurrent and nearly full parasitic drain from a computer board that wasn't shutting down. The bike was built around April 2015 and I bought it in November 2015. The problem was picked up by an alert salesman (who spends time rotating chargers around the show room). After diagnosis and discussion with the mother ship, the board was replaced before sale.

I suspect my bike is not the only one that has had a faulty parasitic board.

so, it wasn't a poor battery? I did mention recurrent parasitic drain. The other potential cause, as many Honda owners will attest, is a faulty regulator on the bike so the battery is boiled to death through overcharging.

Ah, the bain of the '80s Japanese UJM. I'm sure there were many companies launched to deal with the regulator/rectifier & stator problems of that era. As far as my stock RS battery, I swapped mine out in August of last year.

Has anyone identified a Lithium battery jump charger that would fit in the �manual� space under the rider seat? For piece of mind whilst touring that would be an ideal place to store one I think (jump leads/clips somewhere else). I�ve no space left under the pillion seat with Canbus controller and alarm placed there.

My old 1986 Honda VFR700FII that I gave to my daughter and that her husband now rides has 125K miles on the clock and still runs fast enough to for him to receive a ticket for going 95mph in a 55mph speed zone. That bike has never suffered a mechanical failure, but instead has gone through about 10 Voltage regulator/rectifiers, one toasted stator and one electrical fire that partially melted the left side fairing panel. On the other hand, I have never had an electrical problem on any of the 8 BMW motorcycles that I have owned over the past 35 years.

Current motorcycle collection: 2002 Yamaha FZ1; 2020 KTM 390 Duke; 2011 Royal Enfield Bullet 500; 2009 BMW F650GS; 2016 BMW R1200RS; 2018 Zero S 16.6 kWh

The only bike that ever stranded me was my '96 VFR. I remember the companies that would sell cooling fins to put on the R/R. I just started to carry a spare.

I don't worry about batteries...I check their cranking amps and ability to hold a charge every six months or so. When they start to look shady, I just put in a new one.

Not sure but I've just bought one for my Aprilia and it's pretty tiny, I can measure it if you want I can't see dimensions on this link.

Interesting back and forth on possible parasitic factors. We'll see.
But does that really exculpate Beemers- if the batteries are unimpeachable but something else perniciously faulty is??
Look I love the bike. I am trying a new AGM- consumer reports tested battery (a USA institution of "independent" testing and reviews of consumer products like O'Reilly's Chain agm car batteries) . So I am giving it a shot.
Seems to me battery design and manufacture consistency would or could change all the time, and could easily be a weak point from one model year to the next.
And if I'm wrong- hey, man, I get to spend cycles deep-diving in analysis for a hidden electrical gremlin- yeaahhh baby! What could be better?

Did it say on the battery where it was produced?

Is this one small enough? https://antigravitybatteries.com/product...o-starts/sport/
You can use the optional harness so you don't have to carry the clamps. https://antigravitybatteries.com/product...-sport-xp1-xp3/

I carry the larger XP-3 https://antigravitybatteries.com/products/micro-starts/xp-3/

Thanks Lee, that is exactly what I was looking for and those dimensions will fit under the seat, the harness is also a great space saver to tuck behind the battery cover and as you say then there�s no need for clamps , thanks again.

Here's the Superstart O'Reilly AGM battery.
I could have something like Ray B described. Thank you for sharing, Ray. I've saved off your description in a little doc.
I'll "try" my dealer, minutes away where I bought the bike new. They tend to be sleazy. The battery did run down before winter storage, and I couldn't get a followup start.
But this was a little different than the OE battery when it was acting up. That one had ... nothing but dash lights,nothing, nothing,nothing then start fine. Be good for a while. Then repeat the sequence.
I take mine out for charging on a battery tender. It's just me. I don't like- at least at the moment- putting on permanent pigtails for easy charge. I know I can do it, I just want to do a nice job with the "fiddly" parts, as our friends say in UK, and I haven't taken the time yet.

Has anyone been able to scan with their diagnostic reader and find a parasitic fault, I wonder? Or this is likely to be only in the dealer's domain to pickup?

Re. a parasitic drain. Anyone competent with a multimeter should be able to measure a parasitic drain in current mode. Plenty of videos on Youtube https://www.youtube.com/results?search_q...c+battery+drain

Due to the location of the battery on the RS you would need to measure the current at the negative terminal. Locating the source of any parasitic drain is the trickier part. On a vehicle it is usually a case of unplugging stuff to see if that makes a difference. I used to use sophisticated Toneohm resistance meters on electronic circuit boards.
