my last reply was before I had finished reading all the posts, which have all been good and could well have been contributing factors to cold start problems, glad to hear I am not alone anyhow !
Ok well I popped in this morning to where I bought the battery from just over a year ago (2YG) , just like quick fit he tested battery too, he then syringed out the distilled water from one of the cells, it was black. He said that running a split cahrge relay from the battery to my leisure battery for pump and short trips and stop / starts had all taken their toll on the battery. Taxis apparantly change their batteries every few months because of this added wear. So solution was a new battery, not under guarantee as battery was not at fault, well a second hand one for £20 instead of £50, he reckoned a new one was pointless as the way its being used would only give a years use, honest enough of them I feel and I may well just change to a fresh second hand battery every beginning of winter as a matter of course in future.
So for time being I'm a happy bunny again, a few frosty mornings and time will tell though I guess.
Thanks all
Simon
