Im part exchanging my car for my new bike. BMW wont take my car without at least 3months MOT, so i've booked it in for an MOT tomorrow. I went to start the car tonight - battery is dead. Put it on the car charger, but its not taking a charge. Went to get my jumper pack, but thats also dead, and i cant find the charger for my jumper pack, so i'm a bit stuffed. Decided to try the Optimate bike charger on the car battery, so i took the seat off my GSXR to disconnect the Optimate4 charger cable, tried that on the car battery - it tried to "save" the battery then started charging - great! left if for two hours, went to start the car - still too dead, and the car charger wont do anything as it thinks the battery is charged, so i think the car battery is well and truly stuffed. Problem is i need to get the car to the MOT station tomorrow, so I need to jump start, so now i've taken the jumpstart box apart, connected the Optimate4 bike charger to the jumper box battery and hoping i can jump start the car from the jumper box in the morning! What a bloody palaver...
