Your_Boy_Yuriy Posted January 7, 2023 Share Posted January 7, 2023 500uAmps sounds normal to me. Sounds like the battery has plenty of juice to turn over the engine. If the problem persist I would look into the ignition system next. However, its not the easiest to get to the spark plugs and coils. Link to comment Share on other sites More sharing options...

Letting any vehicle sit unused will kill a battery... Well, I found 2 fuse outputs causing the parasitic drain. Total drain is .5ma; .34ma on a 7.5A fuse marked (backup) and .14ma 30 amp marked (ABS motor). I looked up those loads and Backup to basically to backup power to the Clock and odometer as I have suspected, and the ABS motor must need a backup power also. So I guess those parasitic loads are normal and all I need to do is to replace the battery.. I just have to decide AGM vs. Lithium Iron. Thanks for replies...

No more issues if you get a reputable battery. 14.5-14.8V running AFAIK . Battery now if charged is approx 12.2 V, and after trying to start several times is down to 11.9V and will not start bike unless I bring voltage up w/ tendor, but will not last. I tested the battery on a Harbor Freight battery testor which showed it weak after charged up, so I guess it's done. I'm shopping now Lith or AGM.

OZVFR Posted January 8, 2023 Share Posted January 8, 2023 If your battery is only 12.2v fully charged it’s stuffed. It should be around 13.1v. I was going to ask earlier if you tested the battery, I assumed that you had. Link to comment Share on other sites More sharing options...

Well; either way I did assume battery was defective, but I'd like to know what's causing a parasitic draw and to determine Amp/HR performance incase I'd choose a lithium battery replacement because of it draining too quickly destroying battery, but w/ BMS on most Lithium batteries, and choosing a high AH, I should be OK. still not sure which type battery to choose yet though.

Bike is kept inside and occasionally put on battery tender if bike is down for more than a couple of weeks. I had a job where I was out of town about 6 months of the year, for 12 years. The best luck I had was fully charging before going out of town, then DISCONNECTING cables. Did that for about 7 years. No problems. Ironically it was the tender that screwed me. With the older style wet battery (not AGM or lithium) I put a name brand "Battery Tender" on it, thinking it would sense when charged, go into trickle mode, etc. Came home to a dry battery, it was toast. Water boiled out of it. As a diagnostic, you figured out the parasitic draw was negligible. How long was it sitting and if it was a "wet" battery, did the level go down? Just curious. 1980 Yamaha 850 Triple (sold). Too many bikes to list, FJ-09 is next on my list Link to comment Share on other sites More sharing options...

I've got AGM batteries in all my bikes, no more than 2 weeks w/o charge. I'm now also looking @ the Motocross battery. It supposed to be a relabeled Yuasa, and as reliable as OEM; but still only a 1 year warrantee. I'm still on the fence w/ the Lithium Antigravity.

peteinpa Posted January 9, 2023 Share Posted January 9, 2023 (edited) My FJ09 came with a Firepower AGM battery. I never heard of that brand till now. Still works great after 2+ years and 10k miles. In times of non-use put on a battery tender at least once a month. All the time is best. I've been useing Scorpion batteries from Batteries and stuff in my various bikes for 15+ years. usually get 7 years out of a battery. When you receive it, put it on the tender first till solid green before installation. The warranty is a year. Any deffect in a battery will show up by then. The rest is up to you. Motorcycles aren't cars. Their system will keep a good battery good. It won't charge a weak battery well.

I called Batterystuff about my present Scorpion battery, and told me I should have got the Motocross made by Yuasa in Japan vs. the Scorpion made in China, but what do I know !

Ride365 Posted January 9, 2023 Share Posted January 9, 2023 Japanese YUASA for me, that's all I run anymore concerning AGM battery. I can't fathom where there would be a parasitic drain somewhere, unless it is an unswitched outlet with a USB charger plugged in. Link to comment Share on other sites More sharing options...
RaYzerman Posted January 9, 2023 Share Posted January 9, 2023 Any bike with a clock, trip odometers and other computers will have a parasitic drain..... bottom line, connect up to a Battery Tender if it's going to sit a week or more. 2 Link to comment Share on other sites More sharing options...

Will Do ! I ordered the Motocross version AGM Yuasa battery for $132. Hope this one works out, and will be more careful . Link to comment Share on other sites More sharing options...
