7Valleys the time to charge your battery depends on the amp hour rating of the battery as well as what type of amps your charger is putting out.
If you can post that I can give you an accurate time to charge the battery. But like the others you would definately be much better off with an automatic charger so your battery is not overcharged.
I carry these batteries, so if you ever have a hard time locating them, check out my website:
