.......better apart from the fact that you have to buy a BMW branded charger.
. I got mine for £55.00 and am very happy with it 
I have one of the first '04 bikes, and the BMW charger plugs in and works fine without switching on the ign first, and no, i've not had any software updates. Also, the charger works on other vehicle batteries.Things have move on with the ZFE software; the later bikes allow you just to plug in at any time - no need to turn the ignition on the off and plug in while the socket is still active. Much better![]()
If you've more than one bike maybe?
Fit eyelet connections to them all and use one charger. Never seen the BMW one so not sure if it can be adapted for the same purpose?![]()


".......But the BMW charger is excellent . I got mine for £55.00 and am very happy with it...." I would hope so! my little 'optimate' type charger has worked very well for years and cost 40€ - almost exactly half the price of the BMW charger. So as I charge my bike battery about three times a year I feel well compensated for the extreme burden of lifting off the seat!
For those that want to connect to the battery via a plug rather than a lead, buy a weatherproof optimate lead and wire to the underside of the seat and tiewrap to the frame. They're available from ebay for £5 delivered. You get the ease of just plugging in without the fuss and nonsense you get with the BMW charger.

...."What is your problem? ..........it seems from the numerous threads on this subject, that some Optimate users are completely intolerant and cannot understand why anyone should have the temerity to use any other brand."
No, Wilbur, junior - I don't think that I (or we) have any problem; One of the good things about this forum is the amount of advice flying around; Nobody, I repeat NOBODY, is criticizing your choice or your freedom to do/buy/sell whatever you like; but I must say that I have received some VERY USEFUL guidance and saved a great deal of money ( and even made a number of friends) as a result of various ideas found here - and a Merry Christmas to you too! (Please excuse me if I have mis-spelt 'criticizing' - it doesn't look right!)
Here is the one I bought. If you're buying a new Optimate though, I think you now get a waterproof lead with the pack.I can't see any at £5 delivered on EBay..... are you sure?

Ive used an Oxford charger on my last couple of bikes always connected directly to the battery, at present it is connected directly to the battery of my new p&j can this damage the wiring or battery on the bike or is this only when wireing it into the canbus system? I made my lead waterproof with masking tapeMight have to invest in a waterproof lead and spend more money on a new gadget

Can't see you having a problem with that. BMW warn against some chargers that have a de-sulphate mode that may increase the voltage output from the charger to a value that is high enough to damage the electonics in the control unit. Normal chargers designed for small capacity batteries will be fine.![]()
