Sorry but I'm too far away. It's going to take a lot more than some fart fuel and flirting to get me there. Just take your battery out. I've never worked on a ninja 250 but I'm guessing its under the seat. Should be 2 bolts under the back edges of your seat to undo (turn counter clockwise). Then lift the back of your seat and pull it towards the rear of the bike. Now there should be a couple of bolts holding the wires to the terminals undo those. There may be a rubber strap holding down the battery hooked on each side, unhook that. Lift battery out. Now obtain a charger. Pokey offered one earlier. Hook battery to charger. Self explaining. After battery is charged re install it. Reverse instructions on how to remove it. Start the bike. If it won't start something is fucked up, tow it to Hoblick. Or buy a new battery you'll need it. If it starts ride it to Hoblicks place and don't stall it. Once at Hoblicks don't bother flirting you can't compete with his wife. Should be all the help you need to take care of this. Now do it to it.
