I'm thinking of getting one of these...

Hi Speedy,

Here a couple of links to some battery information which might be of interest:-

I've got a Yuasa YTX12BS in mine (150mm x 87mm x 130mm) It's a bit of a tight squeeze but works fine. :clap:

 

Hi All

(Mmmm ... strange one this, if anyone can help!

Use an Optimate 3 sp battery charger to keep battery top shape. Been fine all summer, went in to check the bike yesterday & the red light was on the charger. Reading the instructions it says either the battery is....)

speedy just a long shot, check the inline fuse between the optimiser and the battery.
I had a weird charging problem last year after alot of searching it turned out to be bad connection in the fuse holder, gave it a good clean streched the spring inside the fuse holder and hey presto it was fixed.

 

Thanks all for the usual prompt replies!

Checked the battery on the bench when I got in from work this morning, been on charge for a good 15hrs, & NO red light .... so will assume battery is a-ok!

Put the battery back on the bike ( checked with digital tester ... shows 13.1v ) alarm part sets via immobilizer automatically after 1 min ..... checked again 1 1/2 hrs later & now showing 13.2v .... so assume it may be something to do with the optimate 3 charger?

Will remove the inline fuse & clean as suggested & leave bike for a few days to see if voltage drops significantly .... if not will put optimate back on & re - test over another few days.

Will post results next week for those interested ....

Cheers 'me' dears

Had exactly the same problem, turned out to be the optimate.:blur:

 

FAZMAN .... when you say your Optimate did the same .... what did you do?

Just live with it or exchange for a new one ... or purchase a different make?

Be interested to know .....

Thanks

From what I know Optimates work on measuring the voltage and resistance across the battery to work out the charge level. If the reistance goes high then it assumes a dead battery.

So are you sure you havent just got a dodgy connection, or tripped/run over the wire at some point fracturing the cable.

I have an optimate II that needs a wiggle to get the thing to think that it is not disconnected (disconnected shows the same dead battery red light on mine as a dead battery, ie 100% resistance).

 

I've had a similar problem, mine was caused by corrosion in the multi-plug that connects the charger to the wires you leave bolted to the battery, assuming you have connected it that way.

 

Mmmmm .... try all these ideas when I try the optimate out again next week!

Thanks all

Sorry for the delay in replying Speedyone, what happened was, I contacted optimate about the problem they said it would be the optimate which was faulty and to return it for repair, however because it was out of warranty and I would have to pay I didn't bother.
The fault doesn't happen all the time but when it does I just disconnect from the bike switch the power off for 30min's and then connect and switch on again and it's ok.
I would say it happens about 30% of the time so I just live with it, its been like this for about 6 months and hasn't got any worse.
Hope this helps

Cheers Chris

Taking back to Heine Gerike as I have the receipt & box & is only 6mnts old.
Will let you know the outcome !!!!

Changed the Optimate for an Oxford Maximiser 360T ... paid the extra £10 & told it works much better .... time will tell,Eh! :rolling:
