Mark P Posted March 2, 2016 Report Share Posted March 2, 2016 Am I missing something ? I have decided to replace the battery on my car as it is displaying the exact starting symptoms as in the recent PI article in TR Action. My problem is that all of the batteries I have looked at have the +ve terminal on the right & the -ve terminal on the left. (as you look a the battery from the front). My car has the terminals the other way round. Is this normal ? I can't put the battery in 'back to front' as the cables would not be long enough. Is it possible to get car batteries with the terminals the other way round ? Cheers Quote Link to post Share on other sites
RogerH Posted March 2, 2016 Report Share Posted March 2, 2016 (edited) Hi Mark, are you thinking of this http://www.halfords.com/webapp/wcs/stores/servlet/VehicleProductGuidedSalesCmd?action=getProducts&storeId=10001&catalogId=10151&categoryId=165762&langId=-1&findPartsMMYS=Find&engineInd=&makeName=16&modelName=1610&dvlaYear=7&subsetEngine=1610100&subsetBodyShape=1610060 or the other way round. The HBC072 is similar but without the filler caps http://www.halfords.com/motoring/bulbs-blades-batteries/car-batteries/halfords-calcium-battery-hcb072 or other way round http://www.halfords.com/motoring/bulbs-blades-batteries/car-batteries?storeId=10001&cm_re=Search-_-Onsite+Search+Forced+Redirect-_-car+batteries&langId=-1&catalogId=10151&storeId=10001&catalogId=10151&langId=-1&seo=true&isMobile= Roger4 PS - all Halford Batteries are made by Bosch Edited March 2, 2016 by RogerH Quote Link to post Share on other sites
OAF939M Posted March 2, 2016 Report Share Posted March 2, 2016 Mine is a Bosch. https://advancedbatterysupplies.co.uk/product/bosch-075/ The earth, negative is on the nearside/passenger side. Fits really well and sits in a plastic tray which was on the car when I bought it. Quote Link to post Share on other sites
Nigel Triumph Posted March 3, 2016 Report Share Posted March 3, 2016 I fitted a Halfords HBC072 to my TR6 about 7 years ago. Very impressed, it holds its charge well and the high cold cranking current always starts the car easily , even after standing for a month. Nigel Quote Link to post Share on other sites
OAF939M Posted March 3, 2016 Report Share Posted March 3, 2016 (edited) I have just fitted a new Bosch battery, the old one was just under four years old and was replaced under warranty. The negative battery terminal has an isolator, when I turn the isolator on ,without the ignition being on, I can hear a slight intermittent quiet whirring noise from the nearside rear in the engine bay. What might this be? The previous owner said to always turn the isolator off after use. Edited March 3, 2016 by OAF939M Quote Link to post Share on other sites

TonyC Posted March 4, 2016 Report Share Posted March 4, 2016 Mark, after a bit of research I decided on this one - Exide Excell EB741. CCA of 680A and 74 ah and posts where they should be. Just be sure you don't have an issue with the mounting clamp. If you are non standard here you could end up shorting the posts together. Hope it helps, TonyC Quote Link to post Share on other sites
Mark P Posted March 6, 2016 Author Report Share Posted March 6, 2016 Thanks for all of the suggestions, I went for the Halfords option in the end. It seem does to have improved the starting, but it still doesn't fire on all six initially. Maybe something to do with infrequent use. Quote Link to post Share on other sites
astontr6 Posted March 6, 2016 Report Share Posted March 6, 2016 Hi Mark, It sounds like another case, of injector drain down, of petrol, by passing one or more of the injector(s) inside 'O' Ring(s)? I have commented on this problem many times! The latest formulae of petrol will attack any 'O' Ring or Seal(s) that is not made from Viton B grade (minimum). I also did suffer from this problem?

jean Posted March 10, 2016 Report Share Posted March 10, 2016 As far as I know the original layout was, when standing in front, with the plus terminal at the left. I bought my 70 TR6 in march 73 and it was all original. At the time the batteries were quite different and there was no problem with the bracket. But now with this layout the fixing bracket comes very close to the terminals, as I noticed in latest TR Action on Andrew's car. I overcame this by fitting a wide U shaped rubber over the bracket at the location of the + terminal. The chance of short circuit with the resulting firework is in so far very remote, almost nil. Worth thinking about it. Quote Link to post Share on other sites
Mark P Posted March 10, 2016 Author Report Share Posted March 10, 2016 Thanks Bruce, you are probably right about the drain down, although I replaced them along with the metering unit from Prestige a couple of years ago. Quote Link to post Share on other sites
