How much parasitic draw is too much. By skunkhome (Read 1,284 times)

I went out to find my new battery dead yesterday.  After charging it back up from 6.4 volts I decided to run a test to see how much drain I had on the battery sitting with the ignition off.  The manual says zero but I know the clock in the electronic dash draws something along with other functions preserving memory.  I found that the bike had a parasitic draw of 50mA.  Is that excessive?

i personally don't like any,,,,,i guess the maker thinks a week till it's dead is good,,,i had a couple bikes that i had to put on a tender like religion if they were going to sit for more than a week,,,maddening

ANY draw is bad. If you really want that clock going, then put a small solar panel with a rechargeable battery to run the clock. Anything else should be off and not pulling anything.

More than 10ma will drain your battery pretty quick, I have a Clock/Date built in my instrument panel and it does not drain my battery enough so that it does not start up. But then again I have my machine tuned so that it starts in the 1s or 2nd push of the start button none of this cranking stuff

If you have a serious draw and the battery is down to 6-7 volts it doesn't matter how well tuned your scooter is, It ain't starting.  You won't even get a solenoid click.

Things like that only happens to rookies or people that don't know when the sky is blue in other words spaced out nothing up there but air. Also the magic number for a battery is 9.6.

I agree with cyborg, get the small battery tender and hook it up if the scoot is going to sit for a week or so, its good for the battery also.
