I disagree... all manuals say not to do it....... They dont make that crap up usually....

I've done it and it worked ok .
plus the solar chargers do it too

Then why do manuals don't mention anything about having to use motorcycle-specific oil

By having the ignition switched off, the battery is cut-out effectiverly, except few minor stuff such as clock .. plus, I've done that and the ZX6 did not do a 'suzuki'

you dont have to use motorcycle specific oil..... read that in ACMN

Its probably fine most of the time.... but if you get a power spike and your charger isnt earthed..... and doesnt have a fuse, would you like to buy a new computer?

Seeing KSRC doesnt have a modified version of I'm with stupid (I'm with Stereo)

I'll just say it instead

I'm with Stereo. I've used car oil in bikes and If you had a surge and the battery was plugged in, the ECU die

java it is ok to do that but the manuals say not to do that due to some charging characteristics and charge flowing to ground which is not what u want.

U want to be able to charge the cells in the battery without any charge leakage to ground, also this help with trickle (top up) charging on lead acid batteries.

i think thats what i remember from school/uni

Offer on M/C batteries on page 4

As for the do I - Don't I with charging batteries.........well I don't give a flying f**k.........you do it your way and I'll do it mine

Just ride the fucking thing more often,then you wont need to put a charger on it....end of story.

FFS people...

Buy a decent maintenence charger (like on page 4 of the Battery World link that Rossi put up) which will charge a flat battery then make sure it doesn't drop in voltage (when plugged in of course) which means it wont sulphate which means it will last longer...

I personally would disconnect the battery before charging and I would remove the caps if the battery has them.

but that's just me.

This is 110% sound advice - Ignore it at your Peril. ECU's are *hot*, ie they are *not* disconnected from your 12v supply when the ignition key is turned off............all that does is disconnect the *ignition* system ( ie coils)..........

it only takes 15 seconds to undo an earth lead FFS !!!

thats probably so the clock doesnt forget what time it is i doubt any of the sensitive electronics in the ECU would have constant juice to them?

im still for disconnecting it any way

I cant see how it would hurt the electronics either.I mean its just a constant trickle charge into the battery.Would it not be the same as when the bike is running and the alternator is putting a constant charge into the battery?Do you need to disconnect the battery then?

Its nothing like that at all - you are putting a charge *directly* into the battery, and altogether by-passing the standard regulator, so this comparison is apples v oranges.

Its just good practice to disconnect the battery when hooking up a cheap, unregulated battery charger........thats all. You may well get away with just clipping the alligator terminals to the battery , it may not hurt anything.......until Tumut #3 switches across to Tumut #2, and sends a dirty great spike down the system.........all I know is that in all the years of charging my EFI Zed, I have *never* had a fried computer, and it has *never* been charged with the battery and associated wiring in place.

So tell me why is it different putting 12 volts from a battery charger into a battery different to 12 volts from a regulated alternator?
They still both go directly into the battery and the regulator only regulates the fluctuation of voltage from the alternator?
Just about all chargers i have seen(even the cheapies)have some sort of regulator on them,so as the battery charge increases,the amperage from the charger decreases.I think they would all have to have something like this on them as a safety standard or your battery would simply blow up if you left it on for too long.

usually its ohms law looking after that on the cheapies any way. they still cook batterys if you leave them on for too long
