Bike type -velocity
I was charging the battery other day charged to 13v or so anyways I notice with the key off the battery is draining 0.01 every couple secs with my meter on it does this signify a drain or is it my meter? Btw I removed alarm device from bike it was messed up wiring harness is still there.

Any number of things could be the cause of that but most likely if it's only losing a tenth or less of a volt it will settle after a certain point. The question is: Does it start or do you always need the charger after a few hours of sitting? If you DO need the charger, I'd look into a new battery but if not then most likely you're only seeing the current draw because there's something making contact i.e. the meter itself.

Here's a hint for guys that leave their scooters parked on cement floors for long periods: Try to place some plywood around the area where your kickstand falls. As anyone who rides a scooter or MC will tell you Cement somehow has this property about it which causes the battery to drain due to a solid ground. Leaving a bike on it for a long time will drain the battery so you want to put a barrier between it and the floor. Believe it or not, it works

Scootercapecod - you peaked my curiosity. Apparently the subject of batteries and concrete goes back to the 1940s and many attribute this as a wives tale. Learn something new all the time on this board!! Here's a good thread on the subject. www.vtxoa.com/forums/showthread.php?t=1919 |

It's perfectly normal for the first 5 to 15 minutes after taking the battery off charge for it to drop. When done dropping it's called the recovered voltage. www.batteryfaq.org/ |

Learn something new all the time on this board!! Here's a good thread on the subject. www.vtxoa.com/forums/showthread.php?t=1919 It used to be true with wood and glass batteries, but this is absolutely 100% wrong. Maybe its a chinese scoot thing as i don't have one, but current batteries can be left on the floor and will not drain because of concrete. I leave my scoot on concrete for a month to two at a tim and have never lost charge. for concrete to drain energy it has to make a bridge some how to the positive. wood ang glass batteries would do this because wood is somewhat wet at all times and therefor was able to comduct from the positive and negative to the earth ground. opposites attract, therefore energy flows from hot to ground or pos to neg typically. The scooters kickstand would be grounded therefore neg-earth ground(neg) nothing happens. If anyone says different then google it. |

chinese scoots do mostly come with crappy batteries though.
i think most anyone who would say their drainage is due to concrete just does not want to admit or realize that they have a crappy battery. They could also be old school and therefore never wrong, and not able to change what they believe.
my 2 cents

Here's a good thread on the subject. www.vtxoa.com/forums/showthread.php?t=1919 Sure alot of those MC guys will say that but I hate to tell you it's true! Some people may attribute the battery going dead due to non-use and not getting a charge once in awhile but I've had it happen! A perfectly new battery should NOT go dead on you over a couple of weeks when you go on vacation. I've had it parked and concrete AND I've used plywood etc. The times when I parked on concrete I've ALWAYS had to hit the charger for 15 min whereas other times on any other surface the bike was fine. Go figure... Scooter |

Well if you do believe this is happening then why not put some rubber on the kickstand? Rubber is certainly lighter than plywood.
2 pieces of hose would surely do the trick. Though if this is happening then your positive is bridging to your negative somewhere.

Yep the concrete draining your battery is old wifes tale as they say. First off the batteries in the scoots are not the best by all means and some are marginal at best. And if your scoot happens to have a clock/date display and or alarm it is using juice all the time. So if you leave it sitting there for some weeks it may not have 12.5 or better to turn it over.

In the end lets make sure no one else debates this.
Some believe it, and as me and lefty have said some do not.
If you don't fell comfortable then please go ahead and put some rubber tube on each side of the kickstand, I can guarantee that nothing will change unless your positive has a path to the ground.
If anything changes then something is wrong with your electrical system.
By all means use plywood if you feel so inclined. I just wouldn't break my back for a bad battery.

the plywood is in the garage anyway to one side where i can sit the scoot but aside from whether or not this is a myth, it saves the floor from any potential leaks or drips.
