oldfart Posted December 21, 2016 Share Posted December 21, 2016 Had the bike for 18 months and 21,000 miles. Battery still going strong but I know I just jinxed it by writing this! Link to comment Share on other sites More sharing options...
Premium Member wessie Posted December 21, 2016 Premium Member Share Posted December 21, 2016 Rare for an OE Yuasa not to last 2 years - I assume you have tried charging it with a charger suited to an AGM battery? An old school trickle charger will top up a partially charged AGM battery but it will not recover a completely flat one.

Guest autobiker Posted December 22, 2016 Share Posted December 22, 2016 The OEM Yuasa battery on my FJ is going strong after 1.5 years and 25k miles. The bike starts in one crank and the battery measures >10V across the terminals during cranking. The FJ doesn't have a lot of thirsty electronics from the factory and the engine seems really easy to crank. Unless you take many short trips, the battery should last 2 years easily. In contrast, my previous GS' OEM battery (also a Yuasa) failed the cranking load test after 1 year 10 months and was replaced before a long trip. That bike had lots of electronic gadgets from the factory and a tiny battery. Link to comment Share on other sites More sharing options...
ilanr1 Posted January 19, 2017 Author Share Posted January 19, 2017 Battery must be at least 12.8v on a rest period of a couple of hours Link to comment Share on other sites More sharing options...
ilanr1 Posted January 19, 2017 Author Share Posted January 19, 2017 Below 12.8v you should charge it or replace it. Link to comment Share on other sites More sharing options...
Premium Member DavidS Posted January 19, 2017 Premium Member Share Posted January 19, 2017 Hi , after almost 2 years it looks that i need a new battery , please share your experience with your battery. Thanks Mine is fine after 2 years, but I'm curious, do you park your bike for long periods of time without use - like during the cold winter months? and if so, do you use a battery tender?

ilanr1 Posted January 25, 2017 Author Share Posted January 25, 2017 Battery was replaced , the bike is like 19 months old. Just to let you know , 12.8 volts at least should be on the battery terminals after a 30 min rest. Mine was 12.35 volts and gave me a lot of trouble. The bike was starting and dying , on and off. Just to inform everyone that this battery is not dying completely like the old ones... , the starter is still cranking the motor but the fuel pump is not building enough presure to let it start.

BBB Posted January 25, 2017 Share Posted January 25, 2017 Being a dummy, I thought the starter motor would take more current than the fuel injection system. Red 2015 Tracer, UK spec (well, it was until I started messing with it...) Link to comment Share on other sites More sharing options...
yamahafjrider Posted February 19, 2017 Share Posted February 19, 2017 Mine started going south last fall. I charged it regularly. It quit holding a charge. Just replaced it this week. I bought one of the lithium ion batteries. Wow is that thing light, it feels like an empty plastic box when compared to the factory battery. Fifty percent more CCA and it has a tester built it to the battery. They are supposed to last twice as long as AGM batteries, time will tell. I will probably need to buy a new charger for the new battery. Kurt Link to comment Share on other sites More sharing options...
g8r Posted March 4, 2017 Share Posted March 4, 2017 I took delivery of my FJ in January 2015 and the battery is still strong. When not in use I keep it on a battery tender. Link to comment Share on other sites More sharing options...
duhs10 Posted March 5, 2017 Share Posted March 5, 2017 ...I will probably need to buy a new charger for the new battery... Do they require a different charger than a regular battery tender?

yamahafjrider Posted March 5, 2017 Share Posted March 5, 2017 ...I will probably need to buy a new charger for the new battery... Do they require a different charger than a regular battery tender?Lithium ion batteries have a different charge requirements that a lead acid or gel. The charger must not desulfate the battery. My battery tender charger is over twenty years old and I am unsure if it is safe to use on this type of battery. So I bought one from Amazon just for the lithium ion batteries. I will be buying more of this type of battery in the future. Kurt Link to comment Share on other sites More sharing options...
