Yes, Sarah, my 2018 had a Yuasa and I have heard and understand the supply issue. Did they have a whole warehouse full of the poor quality substitue batteries left that they had to use up? If you look on the BRP website, the Yuasa battery is the battery they are selling as a replacement. I certainly hope they are back to putting these in the new bikes! Thanks for your reply!
I'll bet anything that if they do have a warehouse full of rubbish batteries there's no way the BRP Accountants will allow them to be scrapped. They'll be put into new builds on the hope thay last through of warranty & then they can sell you a Yuasa replacement.
That is useful information. I need to buy the service manual. The alternator has a maximum output of about 100 amps. That should be sufficient to charge the battery during a fairly short ride, unless the bike draws a large amount of current. I wonder if there are any specs. for current draw for lighting, heated seat, and grips, etc?
Thank you so much!! Appreciate this!
Sarah, my 2025 F3-T came with a Chinese battery. It was not the Haijiu, but I had the dealer install a Yuasa before I took delivery.
That is not a valid statement. The alternator is capable of putting out 90 amps max, it is voltage regulated to 14.5 volts and will only provide the current needed by the bikes equipment and also slowly charge the battery. It is not dumping 90 amps into the battery as that would destroy it pretty quickly. Once the battery terminal voltage meets 14.5 no more charging will occur. It takes about a 30 to 60 minute ride to replace the charge taken from the battery to start the engine, you cannot rush that.
I stand corrected. Thanks. However, I didn't assume that 100 A or even 90 A would be used to charge the battery, but I did assume that the battery would recharge faster than in 30 to 60 minutes. I don't understand why starting a well tuned engine would require enough current to require 30 to 60 minutes to recharge. Do you know the amount of current consumed when operating the bike?
I would have done the same, Peder. Or have them knock off enough that I could buy the battery myself. So BRP is still cheaping out on us. The bean counters need their pay docked every time a bad battery report comes in.
Not in my experience. I often run errands "downtown", 7 miles or 10 minutes away, vising 2 or 3 stores within a mile of each other. If what you say is true, my battery would go dead after a few of these runs. It doesn't. I never put it on a charger.
I did not say it won't start your bike, I just said that is what it takes to replace what you use for a start. A good fully charged quality battery will start a bike several times in a row without running out of juice, it just won't be at full charge after the starts and you will eventually deplete it. 10 minutes will replace about 50 % while the last 50 % will take longer, it is just physics.
The battery will take 30 to 60 minute to FULLY recharge, That is why it is not a good idea to start the bike several times over the winter and run it for 10 minutes, you will not replace what was consumed by the start in the short period of time time and a tender will not replace it either. Eventually you will "kill" the battery.
I found my 2018 service manual on the BRP website and the Yuasa YTX24HL-BS is listed as the Battery Type... It's no longer listed in the 2023 manual for my F3L SE6...
So lets' say my starter takes 10A to start, and it runs for 10 seconds. That's about .03Ah. Your saying that it takes 30-60 minutes to restore .03Ah?
Best I can tell the starter motor draws1.4KW when operating, specs gave a range of 100 to 400 amps but I really had to dig for that info. Your guess of 10 amps is probably what the solenoid draws. Either way a starter load draws a tremendous load over a very short period time (thus the CCA rating of 350) but that energy needs to be replaced and you can't put it back as quickly as you drew it out.
The solenoid coil resistance is 5 ohms, so less than 3A.
No argument there, but certainly less than 30 minutes. If it's a 100A draw that's still only .3Ah.
Ok maybe an hour is a bit much but 10 minutes is not enough time to replace 1 % of the battery capacity. You just took 100 amps out of the battery and now you need to replace it. That would be 16.6 amp minutes and assuming the charge rate of the system is low (1 amp or less to avoid over heating the battery) it would take more than 20 minutes to replace it.
According to the specification sheet above, the recommended charging rate for the standard battery in the Spyder is 2 A.
That is for an external charger, not while running down the road, and you should monitor that charging to prevent the battery from overheating
