Bike let me down this morning

...In their FAQ section on their website, Hex Ezcan say this 'I noticed that the ezCAN’s green LED blips every few seconds while the bike is off, is this something I should be concerned about?
Not at all, the maximum draw of those blips is 800μA (microamps)/hour. In order to completely drain a 12V battery, the ezCAN would need to be connected to it for more than a year.'...

That is correct. I haveEzCan and it has never given me a problem in two weeks without touching the bike (it's never been sitting more then two weeks).

I had it on my R1200GSA for 3 years. Denali D4s, sound bomb and brake lights and there was no issue. The bike stood for protracted periods with no issue.

Bit of an update from the dealer yesterday. Battery has been charged and checked and is fine. They are now looking into what is drawing the power from the battery. I spoke to Datatool and they told me the draw from the Stealth unit is less than 1mA when in sleep mode. Sleep mode activates once the ignition is switched off and only 'wakes up' if an event occurs such as the bike moving.

Anyone know the current draw of the BMW alarm........?

yes true, but maybe this or other thing is confusing ecu on bike so bike is not going into sleep mode correctly
 
Bike back and nothing found. battery checked out ok and both charges and holds its charge fine. No parasitic current draw identified either. I will keep an eye on it over the coming weeks. Dealer did recommend connecting to trickle charger if bike wasn't being used.

charger will just push problem back later, better leave bike to see how long battery stay before not working

Yup and agree, hence why it is not on trickle for the next few days.
 
My GS is a year and two weeks old, with 3500 miles. Used most days for short commute, and the occasional ride out.

Going to work this morning, opened the garage, butties in the top box, hit the tit and it goes click. Turned off & on again, same result. Lift to work from the Mrs, called BMW Assist, arranged that they would come when I got home. Colin turned up ten past six, checked the battery, 11.6V, mmm, puts it on the jump start, it starts, leaves it running for 15 minutes, turns it off, disconnects battery, sets battery test, which proclaims the battery to be good. Puts it back together, the Datatool man rings.

Colin reckons that if you leave it two weeks without a run, the battery will be too discharged to start it. The battery is 12Ah 200A, apparently.

Colin’s parting words were, “it should be ok, give us a call if it isn’t and we’ll see about a new battery”.

I give it a week or two at best. Hope it’s at home WHEN it fails because it surely will.

Pretty disappointed TBH.
 
Mine has had the same treatment.

I am just going to buy a new battery. What would folks recommend?

What if the problem is, not being left on a trickle charger?

I don't want to start a war, but trickle charger's ain't that much to buy, will last a long time, and are easy to simply hook up after a ride.
 
Trickle charger is entirely possible, and it would seem that it is necessary.

I’m really surprised that it is required on a new bike which is ridden nearly every day. I get that it’s normal for my classic vehicles, which are used much less frequently.

Either the bike (or the data tag) is using too much current or the battery capacity is absurdly small, or possible all the above.

For me - the a above.

I agree with mr bean, but I have no warranty so can change when I choose, but you also can have battery of your choice, and use old battery for many other things, I use mine to start generator in garden

Would a new battery (disposable/replaceable part) void a warranty claim?

You will have two small fobs. BMW stopped fitting them recently, so if your bike is a very recent one, chances are it has no tracker fitted.

Yup, no tracker fitted, or maybe you should reset the battery settings. If still not working then call them they will guide you better regarding connecting issues!
 
I can’t pick up from the thread what bike is being discussed other than a GSA. However as it seems to have tracker fitted I presume a 1250.
Here is my experience of r1250gs battery problems. My new 2019 bike had a flat battery on two occasions with in the first six months, both of which followed a TFT link up with my iPhone and Scala rider packtalk via Bluetooth. I decided not to attempt pairing again and have not had any further issues since that time. I have a mate with an identical age bike and he has never had a battery problem until last week when against my advice he said he wanted to try pairing the TFT with similar phone and helmet comms. He made the links and it worked fine. A week later he found the battery had drained overnight. Like me, he found that a charge overnight restored function. Neither bikes have trackers fitted and in each case a subsequent visit to the dealer proved that the bikes were not fitted with the rumoured bad batch batteries.
The conclusion I draw seems to point to the TFT pairing in some mysterious way being excessively power hungry. Also, the margin between a charged battery that can turn over the engine and one that can’t is very slim.

I have an Optimate but I don’t think that a new bike should require a battery tender. Standing for 7 days and not starting is pretty poor, especially for a bike in adventure sector.
 
Dealer also warned against leaving the ignition on longer than needed as the TFT screen eats battery power apparently! Who knew?
 
Just had my 2021 GS starting fine after 16 days parked (I was away working). That's the longest period without riding the bike. It's from January this year, 4000 miles.
I have EzCan installed, my phone, GPS and helmet comms paired.
I have never had any battery problem and the bike hasn't ever been connected to any kind of charger.
