SwissZ Posted April 1, 2016 Share Posted April 1, 2016 Hi Due to naff weather for the last couple of months I didn't get chance to drive my Z. First time I tried starting it, it only just made it, turning over really slowly to begin with. I took it for a good hours run to get some charge in and after that it seemed ok again. I'm now noticing if I leave it for a few days, it will start, but not instantly like normal. Also the volts seem all over the place, sometimes up at just over 14, sometimes 13 and if I just switch on the ignition without starting it's a mm below 12V. Do I just need a new battery or is something else maybe wrong? Cheers Quote Link to comment Share on other sites More sharing options...
brillomaster Posted April 1, 2016 Share Posted April 1, 2016 a new battery would certainly solve those problems, however I wouldn't say it needed replacing just yet. with regular use in the warmer months i'm sure it'll last till the end of the year, then i'd perhaps think about a replacement.

davey_83 Posted April 1, 2016 Share Posted April 1, 2016 change it now, not worth the risk imho. its the same costs whether you replace it the weekend or in 6 months time. 1 Quote Link to comment Share on other sites More sharing options...
SwissZ Posted April 1, 2016 Author Share Posted April 1, 2016 I'm going to give it a proper run out to see if it gets better, but any suggestions on what battery to get if there's no change? I only really use it when the weather's decent so it can be stood for weeks and then run for weeks as a daily. Just need something that holds the charge well when it's not being run. With garage cost, insurance etc, I was actually considering selling up as it was stood for so long.... But then I drove it again Quote Link to comment Share on other sites More sharing options...
davey_83 Posted April 1, 2016 Share Posted April 1, 2016 Any new battery comes with at least 3yrs warranty, so any i think will be fine if looked after Quote Link to comment Share on other sites More sharing options...
GreenLandy Posted April 1, 2016 Share Posted April 1, 2016 Leaving it sitting never does a battery any good. I use a CTEK trickle charge on the Land Rover and it starts instantly, when before it used to take 15 seconds of poor turning over before it would start. It also has a reconditioning setting, which may save your battery as it is now. Although if it were me I'd just buy a new one and keep it healthy. 1 Quote Link to comment Share on other sites More sharing options...
RobPhoboS Posted April 1, 2016 Share Posted April 1, 2016 It'll f- you over when you really don't want it to. Replace it IMHO. 2 Quote Link to comment Share on other sites More sharing options...
ioneabee Posted April 1, 2016 Share Posted April 1, 2016 as greenlandy - get a ctek (other models are available) trickle charger mine sits for about 3-4 days at a time and I plug it in - no worries or issues but definitely consider replacing it anyway Quote Link to comment Share on other sites More sharing options...
glrnet Posted April 1, 2016 Share Posted April 1, 2016 The battery had suffered a partial deep discharge and it is possible that sulphation has occurred. Normal use MAY cure the problem but it is unlikely. Personally I would invest in a new battery and a ctek charger give the times you leave the car standing for long periods of time 👠Sent from my Zed using Nangkang tyres front, RE040's rear 1 Quote Link to comment Share on other sites More sharing options...
SwissZ Posted April 1, 2016 Author Share Posted April 1, 2016 It'll f- you over when you really don't want it to. Replace it IMHO. Yep, that's what I'm afraid of. Can't use a trickle charger easily as it's parked in a shared garage with no power nearby unfortunately. New battery it is! Thanks for the advice 1 Quote Link to comment Share on other sites More sharing options...
GreenLandy Posted April 1, 2016 Share Posted April 1, 2016 Any chance of using a solar-powered trickle charger then? Would be better than nothing Quote Link to comment Share on other sites More sharing options...
davey_83 Posted April 1, 2016 Share Posted April 1, 2016 Car should be fine for at least a month and still start no issues. Quote Link to comment Share on other sites More sharing options...
Mopedmark Posted April 2, 2016 Share Posted April 2, 2016 Well that was hard work for a new battery 1 Quote Link to comment Share on other sites More sharing options...
