Current draw when off

[fugz]

Has anyone measured the current drawn from the battery when off.

Not really necessary unless you're killing batteries. I keep mine on a tender whenever I'm not riding it just out of habit.

 

[fugz]

I have already changed the battery and its always on a tender. I just forgot to measure the current when changing it. I remember it sparking on the terminal when connecting. Which means it must be more than a few mA.
I'll take the cover off an get a DVM.

If you dont have any aftermarket accessories, then its little to none.

Some aftermarket turn signals draw current.

I never kept mine on a tender during the winters and it was always fine.

Mine,

43 milliAmps?

(also how accurate is your tool, full scale is 20Amps in this picture, so you’re measuring in the margin of error)

 

[Massimo]

The scale is on 2Amps, 0.043Amps is 43 milliAmps ! How accurate my tool is I don't know but I bought it in the Netherlands, and you should know the only sell quality there !

 

[Max Kool]

If it’s Dutch it must be good 😌

Serious, on a 14Ah battery that means it's run down after 350 hours (14 / 0.040 = 350). Assuming a bike won't start if the battery is below 30% that would mean your bike won't start after 10 days...

That can't be right. If I leave my bike in the garage for three weeks it fires right up, and a battery tender will quit after 10 minutes saying the battery is full...

That's a clamp meter. Notoriously inaccurate on small measurements. I'll find my inline amp meter later. AVO 8

Fluke, 1.6 mA

 

[Massimo]

Eone 1.6 mA

That's more in line with what I expected. That may be less than the self discharge of the battery.

 

[fugz]

Interesting. So even without a tender it should last for weeks (with a decent battery)

Cheers for the info.

Special for you Max I took 3 times the battery cover off !

 

[Max Kool]

And it does.

I love you back 😘
