PhilR Posted December 8, 2012 Report Share Posted December 8, 2012 (edited) Went to a proper garage today to get it tested and they say its the battery, the battery is ok at 12.87v goes up to 14.3 on idle. but it is rated at 830A and only giving out 691A. Dont know what these numbers mean but been told to replace battery. The CCA is rated in Amps in your battery's case 830 which is the current to spin the starter motor. Yours is only producing 691 Amps which is not sufficient to do the job in cold weather. The same problem I had in a previous post. I think you said this battery was new so I'd be inclined to take it back to the supplier and get it replaced, most batteries these days come with several years warranty.

matone Posted December 8, 2012 Report Share Posted December 8, 2012 As I said,seen this many times,batteries can test within limits but just not up to the job on cold days ! At least it`s a relatively cheap fix ! Quote Link to comment Share on other sites More sharing options...

bruno22rf Posted December 10, 2012 Report Share Posted December 10, 2012 Might be a good time to remind people that buying a "heavy duty" battery is not allways a wise move.If your alternator is not designed to provide the additional power needed to keep the battery charged fully then it will not reach its full potential and will provide less power and not last as long as a standard battery would.

Gozzy Posted December 11, 2012 Report Share Posted December 11, 2012 Test starter motor current draw using amp clamp and potential differance from battery live to starter live also battery earth to starter body using volt meter do this when cranking. Battery test results seem reasonable enough , what are you trying to start the ark royal ? Also voltage across battery while cranking , is it going below 9.5 volts ?

scimitar Posted December 12, 2012 Author Report Share Posted December 12, 2012 Problem sorted, had new varta battery fitted on Monday. As broken battery was only fitted a few weeks ago it was exchanged for free. Started first time yesterday and today. Quote Link to comment Share on other sites More sharing options...
