16' 300rr EATS new dash batteries (CR2032)

19 posts in this topic

Hi guys. First time poster on here.

2 weeks ago I bought a 2016 300rr. The "Low Battery" warning icon was on the computer. So I changed the battery out for a new one (CR2032 btw)

About 5 mins later the Low battery icon appeared on the dash again. I thought maybe I had a faulty battery but it has happened again with 2 more new batteries.

I rang the dealer I bought it off today and he told me to check some connectors that hang under the main battery behind the left side number plate. These look fine to my untrained eye. (Ive never had a bike with electronics before. Always had Motocross bikes) Pics below...

I 'm waiting on a reply from the dealer but I thought I would ask you guys also in case you might have run into the problem before and knew a fix for it? Also the dealer is over 2 hours away so would love to fix it myself without having to travel.

Cheers dudes!

If anything I'd take the connections apart, clean them with contact cleaner, and apply a little dielectric grease and see if that fixes the problem.

There is already a thread on this issue.

IMHO, the batteries are defective in every case. I had to buy 10 before I found batteries that would last more than 2 months.

Others here believe that batteries are somehow supposed to be charged by the electrcial system, keeping them alive.  No proof has been offered of this.

The last battery I installed has lasted 7 mo now.

Got mine November of 13, still has original battery. Bike must be doing something.

Same here.  My bike is a 2015 and I've never changed the battery.

14 month old '16 500RS. Original battery in Dash (not sure if RS is wired differently).

Remove the insulation off those two components, inside you will find one large capacitor in one & three diodes in the other. Check for water contamination & or broken wires. Also check your main earths, two on the ignition coil & one large one from the battery to the frame under the rear of the tank.
Hope this helps.

Thanks man! Didn't want to go digging in there if there was no need too, but it looks like you were 100% correct.  Opened up the capacitor and sure enough there was some old brown water residue in there. Capacitor also has a small dent in it.

All cleaned and dry now and wrapped and greased up and so far so good.

edit: 20 mins later.... Low battery is flashing up on the dash. Might it be the dent in the capacitor thats causing it?

Disconnect the Trailtech from the bike and see if it still eats batteries.  That way you'll know if it's the computer itself or wiring on the bike.

What the capacitor does is smooth out voltage spikes, hard to explain but an engine does not have a consistent rhythmic rotation (dang dang dang) the capacitor stores & hold a charge for the inbetween dangs if you will to smooth it out the voltage. If it is damaged like that, I would replace it.

Cheers fella. Yea the dealer says he is sending me out a replacement capacitor. Hopefully that'll sort it out.

I had the same problem on my 2016 250rr.  Used several fresh date coded Energizer batteries.  In my opinion, there is nothing wrong with your bike or the battery other than a design that will rapidly drain the CR2032 battery.  I eventually fixed mine by wiring the 12 volt battery into the bike electrical system (lights, odometer, horn, etc.).  There are various ways to do this.  The 12 volt battery is normally isolated from the bike electrical system for all purposes other than starting.

I have my opinion about root cause which I won't go into and it doesn't matter anyway.  Bottom line is that tapping the 12 volt battery was the only way I was able to fix it.

I am on my original battery on my 2016 Beta 300rr RE.  Bought it brand new and have owned it for one year 4 months.  I keep waiting for it to go dead but it hasn't shown any sign of it yet.

I replaced 10+ stock computer batteries and the replacement computer battery died half way through the first ride. I'll check the capacitor to see if it's dented and grease all the connections. I read a while back that some folks think the problem has something to do with the oil injection. I'd really hope I can figure this out soon so I can have a functioning odometer.

I have replaced the ODO 2032 battery 5 times so far since 9/2/15 in my '16 300RR.  

Sierra BMW & Beta just mailed me "upgraded diode and condenser units" for the 300RR as part of a factory recall.  Even though I did remove the factory oil injection system earlier, I will install these upgraded items anyway to see if ODO battery life can be extended.  

I just now replaced the battery for the 5th time.  The new battery measured 3.26 V while the old battery measured 2.79 V.  Its difficult to believe why this apparently small level of discharge would impact battery function so much!

      The do it all bike doesnt exist, I know that, but Im looking for something pretty damn near close to it. My dilema: I live in Mexico and It is one of the most biodiverse places you can possibly think of; I can ride at 12,000 feet between pines, the next day shred a desert, and the last day be in a tropical forest. Any thoughts on a bike that you may think can handle all of these relatively well?
       
      Gracias amigos!

      I have a '13 Beta Evo 4T trials bike that likes to backfire on deceleration, it's pretty annoying. Looking at the parts book, there is no gasket, o-ring or anything else that goes between the exhaust port and the headpipe. The  headpipe isnt deformed or damaged, nor is the sleeve at the exhaust port that the headpipe fits over. Does anyone else have the same problem? What did you do to fix it?

      I just picked up my 2018 Beta Evo 200. The dealer included a few things in the box, such as the owners manual CD, a liter of premix oil, the rest of a liter of tranny oil, and a horn and a speedometer.
      Why in the world do they included the horn and speedo? The horn looks to be barely worthy of a kid's toy car, and the speedo might work on a bicycle. Why not skip those two valuable parts and lower the price of the bike by a huge amount, say $5?
      Does anyone have a use for them?

      This is my first post so hopefully I have this in the right area.
      So I'm looking to buy a new bike in a few months and can't decide what Beta to buy. I am going between an xtrainer, a 300rr or the 390rs. I know they have slightly different areas that they excel. I am coming from a 1998 xr400 and an xr250. My question is do any of these new bikes I am looking at have good off idle torque, like slow speed tractor torque. Both my xr's could chug along and climb almost anything but they are heavy and getting older. I dabbled in trials for a bit so I really like the low end pull of thoses 2 strokes, but I also have had a few mx bikes that had nothing down low. What are the beta 2 stokes like. Also does the 390 have a pretty low first gear if I go the 4 stroke route. I ride some pretty rough single track in Georgetown ca if anyone is familiar with that. Lots of switch backs and no room to get speed over some of the obstacles. I am more of a technical rider, don't do much high speed stuff so I'm not to worried about the soft suspension of the xtrainer. 
      For backround I am 200 lbs, 6ft, I'm a decent rider but don't race or anything. I have had loads of Japanese bikes and I am wanting to try out a European enduro, this would be my first new bike. Hope the post isn't to long. Thanks

      Up for sale Ohlins  TTX shock and RXF48mm forks & Brembo front brake assembly off of a 2015 Beta  250rr. They are from the Boana racing team, sprung for a 175lb rider. This is a great opportunity to grab a very rare Ohlins set up for your Beta! I am a 145lbs, so unfortunately I don't have the money to have them set up for me, I am just looking to get my money back. I was really looking forward to using them, but some times life gets the best of you, lol. Hope they go to a good home, where someone will get use out of them!
