Supporting Member dazzler24 Posted January 8, 2020 Supporting Member Share Posted January 8, 2020 @MartyP - This thread might be a start or guide for what you seek. If you're looking for a direct replacement then it's a +1 for Betony's post above but there are alternatives. FWIW I replaced mine with the Yausa OEM original - Pricey, but each to their own. 1 Link to comment Share on other sites More sharing options...
BBB Posted January 8, 2020 Share Posted January 8, 2020 Be extremely careful when you put the new battery in @MartyP. The battery lays on its side and a few people have got the polarity of the terminals swapped, with fuse blowing results. 2 Red 2015 Tracer, UK spec (well, it was until I started messing with it...)

Been there and done that. 😬 There is nothing like spending a day riding with friends in the grip of a shared obsession. Link to comment Share on other sites More sharing options...

Can you just drop the Yausa in or do you have to flip it around to match the terminals? Link to comment Share on other sites More sharing options...

Yes, you will want to install it in the correct orientation, pos to pos and neg to neg. 1 1 ***2015 Candy Red FJ-09*** Link to comment Share on other sites More sharing options...
MartyP Posted January 24, 2020 Author Share Posted January 24, 2020 What's the ideal RPM's and gear for optimal charging of the battery. I do a short commute to work 6 miles 30 minutes and I am having issues with my battery holding charge. My scorpio reads 12.5 most of the time and occasionally it will got to 14.1 if I do a longer ride. Thanks Link to comment Share on other sites More sharing options...
Supporting Member roadrash83 Posted January 24, 2020 Supporting Member Share Posted January 24, 2020 @MartyP I would keep the battery on a tender when not riding to keep it at full charge. Heated gear and other electric accessories can drain the battery in stop and go low rpm riding. The stator puts out more power as rpm increase. He who dies with the most toys wins.

MartyP Posted January 24, 2020 Author Share Posted January 24, 2020 I live in an apartment and have no outlets to plug the bike in. I have to use a battery pack and only lasts a day. Link to comment Share on other sites More sharing options...

That’s not far in the FJ’s rpm range but there you go. you need to run an extension cord and charge it properly overnight somehow. The bike WILL NOT charge a weak battery, it will only keep a regularly used and charged battery topped off. -Skip Link to comment Share on other sites More sharing options...

I have to use a battery pack and only lasts a day. If the battery charge only lasts a day, it sounds like its time for a new battery. If you have a multi-meter, check the battery.

MartyP Posted January 24, 2020 Author Share Posted January 24, 2020 I meant the battery pack that I plug my tender into it only lasts a day. Looking at a battery generator but they are $$. I do have a volt meter and my alarm has one as well. currently it show 12.5 Link to comment Share on other sites More sharing options...
skipperT Posted January 24, 2020 Share Posted January 24, 2020 Low. The FJ starts best around when it has 12.7-12.9v to play with. here’s another test: turn on your key and let the bike sit powered-on for about 30 seconds. Measure your battery voltage with key still on. Less than 12.1-12.2? Dipping well below 12v? 11.8 or less? Your battery is toast. -Skip 2 1 Link to comment Share on other sites More sharing options...
Supporting Member dazzler24 Posted January 25, 2020 Supporting Member Share Posted January 25, 2020 My experience with a failing battery was that the bike, on occassions, would simply not engage the starter motor even though all other indicators would lead me to believe that the battery was fine. I can only assume in retrospect, and if someone knows for sure feel free to chime in, that when I'd hit the starter the battery voltage would dip below the threshold that the ECU says - "voltage too low, I'm not even going to let you try to start for your own protection". The battery must have been right on the 'edge' because as I already mentioned the bike would refuse to start but after a couple of attempts it would fire and probably put just enough back into the battery on the subsequent ride to keep it alive - just! Anyway, after I bit the bullet and installed a new battery the problem magically disappeared! Just a little FYI for those that may experience this in the future. 1 Link to comment Share on other sites More sharing options...
