radders my battery in the bmw just died one night

i towed xrt-si's car to paul hills with it ( there was the first mistake ), drove back at a reasonable pace ) he was holding on to the handle,,,, but he was still shaken from being towed in the outside lane on the A12 overtaking cars whilst on a tow bar in and out of traffic with a bloke who dont use indicators ( must be a BMW thing)

anyway after the spirited drive there and back we went to get fuel,,, car would not fucking start again,, wouldnt even lock the fucking doors ( had to use the key,,,, imagine having to do that )

the batt just died,,,, aparently that can happen

trip to halfords boyo or get me the bat code and ill see what i can do for ya
