Battery charging on the bike,(K1) - SV650.org

All the literature seems to tell me to disconnect the battery before putting a charger on it. Is that a safety measure in case of sparking off a fire or what?

Probably just covering their backsides I`de say

Had mine hard wired to the optimate with the leads provided so its just a case of plugging in when i park up at home and then unplug when i`am ready and willing the next time.

Had mine like this for almost 2 years now with no probs

As long as you use a trickle charger like an Optimate you are fine to charge on the bike.You shouldn't use a boost charger on a bike battery at all,but if you do,I think you should disconnect it first.
Moral of the story?-----Get an Optimate----Worth it's weight in gold.

I've got a 300 mAmp trickle charger, will that do? Where is the best place to get an optimate?

Thanks for the link, just bought one!

Going back to the original question, I think it dates from when alternator diode packs weren't particularly robust and chargers tended to deliver rather high voltages with little or no regulation.

Most modern chargers like Optimates etc are well controlled and won't ramp the voltage up to levels likely to blow diodes etc, plus automotive electronics, things like ECU's, are specified and tested far more rigorously that they used to be and are much more robust.

Also as said earlier, if they say disconnect the battery and you don't, they wash their hands of any responsibility.

Thanks embee..

I suspected that it would be something like that.

Is there anything on the market which would provide a decent interface from a battery(ie not croc clips), into which you could plug a charger, or an accessory like a pump?

Optimate has a host of accessories
http://www.inter-bike.co.uk/inter-bi...categoryid=170

Alternatively fit a std car type "ciggy lighter" socket somewhere. Always have a suitable fuse in line.

I have used a marine grade socket from Maplins before, good quality, around £8 if I recall ("Sutar" I think

), can't find it on the website though.

Or here

Be aware there's the normal car type ciggy lighter and then there's the DIN type (smaller) as used by BMW bikes etc.
