I was trying to find a simple and short video on this topic, but couldn't, so I made one myself for others in the same situation!
I got a scooter, it wouldn't crank, I figure out the battery is dead, then I realize I have no charger, so I resorted to using another fellow 12V lead acid battery to charge this one.
If you don't know, you want the battery to remain at around 12.7V, anything under 12V is pretty much dead and needs to be charged.
Thank you!
(Btw, like I say in the video, I don't recommend anyone do this because it could be dangerous!)
