Ive just gone back to check my bike before its forst run of the year this weekend and the battery is flat.

Is there anything i need to be aware of before charing the battery up. Im planning to remove the fairing and just clamp the charger onto the battery in situ with the connectors still connected.

is this a good idea or should i be doing something different.

Yours technophobically

No problem - but ensure that it is a motorcycle specific charger, like Optimate, otherwise you will fry the battery.

Be aware that a small battery that has been sitting flat will likely never recover. It may be able to start the bike when it's fresh off the charger... but it may be unreliable at best.

These smaller batteries don't handle being left low on cycle very well at all.

I'm betting you'll be shopping for a new battery soon.

Optimates and Battery Tenders when used consistently on good batteries make them last a loooong time. So it's best to run a hook up wire to the battery so you can just plug the bike in, when it's to be sitting for a while.

I was using a cheaper tender , unlike the Optimate that I have just replaced it with. The old one never let me down, it's just one of the wires frayed , so got myself the optimate last night. Just wired the plug onto the battery. Ignition would come on but it werent going to start.
Now many years ago I had my Grandad pushing me around on my KH250 trying to bump start it. Reason ... while cleaning the bike I had pushed the kill switch to off. Did same tonight . But that experience all them years ago , told me to check it first. Well not quiet first. Did think about what fuses I may have blown etc blind panick bad language un all that stuff first. :mrgreen:

Ok, this may start a lot of opinions but I'm gonna tell it anyway.

I've just replaced my 4 1/2 year old battery. I always put the Optimate on if the bike is not being used for a few days. The Optimate is plugged in during the winter lay-off and left on. I've done this for the last 3 years, the bike was previously used in winter for commuting.

So, when I went to see my local battery specialist, he told me that even an Optimate will bugger the battery if left on all the time. Simply because the battery is receiving an almost constant trickle charge. I suppose that made kinda sense.

It's hard to say if he is right or wrong, considering my battery lasted this long - or maybe it would have lasted even longer if I hadn't been Optimated so much?.

Who knows......

So what's the rough cost of a new battery?
'rough cost' is right. Aus$130, or about 30% more expensive than a 550CCA car battery :roll:

On my '98 R1 I bought a Battery Tender Plus with the bike in May of '98 and used it year round whenever the bike was in the garage. I sold the bike with the original battery still in it 5 years later and it spun the engine like it was new. I run a Battery Tender Jr. on my dirt bike, same thing, whenever it's not being ridden, it's on the BT. Same story, bike still spins like new 2 1/2 years later.

So yeah rabbit, I'm not sure what to make of your specialist's opinion cause it's sure different from my personal experience.

I tend to leave if off if I have been out on a run in winter. Put it on again a few days later. Summer when do more miles , only if not riding it for week or two then hook it up again.

Battery charging issues...

Mine is a Nov'2003 model and my battery is starting to run flat even after a short run. That means 2 1/2 years on a new battery. It is the original battery and has been on an Optimate since new. I do have a Data Tool III alarm/immob fitted, which under normal circumstances will drain the battery in about 3 weeks if left off trickle charge. With lights, fan, screen etc. there must be a fair drain on the tiny battery. Are they GEL type fitted to the FJR's or lead acid? What is the part number for a new item? Any feedback on the best long lasting make of replacement battery i.e. Yuasa, Varta etc.?

Yer mines a 03 same battery . No worries. Silver Bike though....!

Change subject , my 03 done just short 20,000m now. Like the last bike I had , they realy do start to come into there own. In my opinion , it's only now I realy feel it's run in. It seems to run so dam smooth , pulls like a dream . Dont know if it's my imagination or what. But felt the same with other bikes, when they got to that sort of milage.

Try and sell a bike with that kind of milage.......

Interested to hear other views.

Mines only half that but I agree, it is getting better with more miles on the clock. I shouldn't get too hung up about the mileage though, the things are built to last over the 100k if well serviced. My mate has a 180k FJ11 and it's still going strong. Look at the BMW fraternity, they hold their value even with a relatively 'low' mileage of 40k. Why you thinkin of selling out...?

My OEM battery lasted 4 years before letting go not bad really.

As for getting better I totally agree my motor is sweet.

The gel cell and newer mat construction with last well even if they only continue to work through the still functioning but vulnerable to vibration end stage that garden variety lead acid batteries reach towards the end of their reliable service life. I also like the added no leak function if the bike goes down.

Thanks for the swift feedback guys. I tried to order an OEM from three dealers today, all out of stock. Spoke with the FJR owners club and they say they are on back order until late July'06! Come on own up you guys, all your batteries must be goin' to get that drain on the spares.

I'll order one through mail order with a 24hr turn around and see where we go from there. Cheers. :ale:

I've jumped mine from a truck battery and the last time (I left the lights on for a week) I just put it on a trickle charger for 12 hours. No problems yet!

Battery

I found a battery company on the web that offered me a VARTA Gel YT14B-BS for £56 inc. VAT + £5.53 p&p (UPS next day). I'll give this a go and see how it lasts.

The web site is www.mdsbattery.co.uk if anyone is interested. Cheers :ale:
