so i just bought a new battery for my 2003 Ninja 250. The battery i bought is a YTX7-BS.
I added the electrolyte at 1:20 i put the cap on the battery at 1:40 it says let the battery sit for 30Mins. so the plates can absorb all the electrolyte. so that would be around (2:10pm) is it okay then to put in a bike then? or does it need to sit for hours?!

the buyer of my bike is gonna be here at 3pm.

 

No you can put it in the bike, or you could put it on a slow trickle charge overnight just to top it off. Oh and welcome to the forums!
