i would recomend picking up a trikle charger and leaveing it on lowest setting over night

 

Agree with the slow overnight charge. Also, totally discharging the battery like you did may have damaged the battery. It may have to be replaced. Standard auto & bike battries are not made to withstand a "deep cycle" discharge.

 

When a battery is charged or discharged, this initially affects only the reacting chemicals, which are at the interface between the electrodes and the electrolyte. With time, these chemicals at the interface, which we will call an "interface charge", spread by diffusion throughout the volume of the active material.
If a battery has been completely discharged (e.g. the car lights were left on overnight) and next is given a fast charge for only a few minutes, then during the short charging time it develops only a charge near the interface. After a few hours this interface charge will spread to the volume of the electrode and electrolyte, leading to an interface charge so low that it may be insufficient to start the car.[2]
On the other hand, if the battery is given a slow charge, which takes longer, then the battery will become more fully charged, since then the interface charge has time to redistribute to the volume of the electrodes and electrolyte, and yet is replenished by the charger.

 

Done that to mine not to long ago used the trickle charge but i talked to the dealer and they told me if it would start i could ride it and it would take about an hour to fully recharge it. so if you don't have the time to ride it any auto parts store you can get the trickle chargers stating around 20 and working there way up depend on what you are willing to spend and all the extra bells and whistles the basic worked for me.

 

thanks man i have today off so i plan on riding all day ....that should do it

i would pick up one of the cheap chargers mine was only 25 at advance auto and it comes with a plug that you put on the battery terminals and you can route it so all you have to do is plug into the charger when ever you want to with out have to take seat off or battery out will come in very handy this winter any way. good luck

 

Best on the market:

Forgot its a yuasa: Product Number: YUA1201501

 

I have done that... twice. First time I ended up having to buy a new battery because I fried it, and the second time I was able to jump it and ride it until it charged back up. I am pretty careful to make sure that the key is all the way in the off position now.
