Biggy Posted December 8, 2012 Report Share Posted December 8, 2012 yes, it was dark so lights on so how would you expect a dead flat battery to charge that quickly? Link to comment Share on other sites More sharing options...

kittii13 Posted December 8, 2012 Author Report Share Posted December 8, 2012 It's a dead battery, buy a new one you dont think its worth fully charging? cant afford a new one so i cant work for a while if charging it doesnt work Link to comment Share on other sites More sharing options...
arizona Posted December 8, 2012 Report Share Posted December 8, 2012 if you got a charger there, stick it on overnight and see what happens Link to comment Share on other sites More sharing options...
Mek Posted December 8, 2012 Report Share Posted December 8, 2012 you dont think its worth fully charging? cant afford a new one so i cant work for a while if charging it doesnt work You coul try checking the ionised water levels if its not self maintaining and topping it up may help but ultimately a new battery is needed. I had this with mine and every morning it was hammering the starter motor to get it to turn over. You could try battery chargers just to keep a charge running in to it but ultimately until you get a new battery it's gonna be a bit of a battle :/ Link to comment Share on other sites More sharing options...
Ant Baker Posted December 8, 2012 Report Share Posted December 8, 2012 Usually a dead battery is caused by the water/acid level running too low and the plates inside the cells warping and touching together allowing the anode and cathode to touch so if it is dead flat then adding water will not work...if it turns the engine but very slowly and then starts clicking rapidly then you can try topping up and charging overnight...make sure to leave the caps off the battery when charging to allow it to vent...if you are going to charge it make sure you top up the battery with DISTILLED water which you can get cheap at tescos of halfrauds if you dont top it up first you can risk warping plates that were good Link to comment Share on other sites More sharing options...
dazzaboy Posted December 9, 2012 Report Share Posted December 9, 2012 does sound like battery give it a full charge cheaper chargers can cook or boil em over charges em at too high ampage best to use a smart battery charger like a ctek one i got 1 for about £40 well worth it or an oximate what bikers use to keep them charged over winter they condition the battery and can tell you if battery knackered they trickle charge slowly. hope this helps Daz Link to comment Share on other sites More sharing options...
_Chris_ Posted December 9, 2012 Report Share Posted December 9, 2012 Does the starter just click, or does it turn but very slow ? Do the dash lights go very dim when trying to start, or do they stay bright ? If they go very dim then battery voltage is dropping badly so bad battery or jammed motor (as below) Alternators are able to supply far more current than headlights draw. They will not stop it charging. A few possibilities: Contacts on starter solenoid worn so it needs a good kick to make contact and turn starter. A battery that's stood is normally about 12 - 12.5V a running engine is about 14 so jump leads will give it a little extra. Starter motor has a worn bearing causing motor to rub on stator when side load applied, thereby drawing more current. Battery is indeed knackered, although it's very rare that they are unable to re-start a car immediately after switching off. Out of interest, did your battery work in Daves car ? Another possibility is a poor connection on power lead from battery to starter or especially earth lead from battery to engine. If you connected the jump lead - to engine rather than battery would have made all the difference. Link to comment Share on other sites More sharing options...

kittii13 Posted December 9, 2012 Author Report Share Posted December 9, 2012 ok we have progress but its weird first tried starting my car with my battery, no luck switched batteries round, daves in mine, mine in daves. daves in mine started first time and is running at 14.2v mine in daves was slightly hesitant but did start first time and is running at 12.4v is it possible that daves car (rev3 engine) needs less power to start up than mine?

Lex_GTS Posted December 9, 2012 Report Share Posted December 9, 2012 Stick the battery on charge overnight, I don't see what the problem with this is? Cold weather + one hour charge on alternator isn't gonna do what it needs to. Needs to be on overnight and maybe you'll get some life out of it.

kittii13 Posted December 9, 2012 Author Report Share Posted December 9, 2012 Was Daves engine warm? no, not ran it since yesterday ok the plot thickens. we put my old battery, the one the AA guy said was completely dead into daves car and it started first time and is running at 14.2v dave is going to check the earths, we know of 2, on top of the gear box and near the headlights. are there anymore on a gen 5? Stick the battery on charge overnight, I don't see what the problem with this is? Cold weather + one hour charge on alternator isn't gonna do what it needs to. Needs to be on overnight and maybe you'll get some life out of it. the problem is that our 3 batteries all work in daves car including the one the AA guy declared as dead and the only battery that seems to work in mine is daves. its clearly not a battery problem Link to comment Share on other sites More sharing options...
Biggy Posted December 9, 2012 Report Share Posted December 9, 2012 I think it is a Battery issue...IMO... If it was an earth issue?why would Daves Battery work in your car? Link to comment Share on other sites More sharing options...
princy Posted December 9, 2012 Report Share Posted December 9, 2012 Best bet is to charge the battery overnight and take it somewhere like Kwik Fit for a free battery discharge test, I wouldn't normally recommend them but they can't really screw that up, this will conclusively tell you if the battery is goosed or not Link to comment Share on other sites More sharing options...

That'll last you a day atleast and you can find out if the neighbour has given you a dud or not. Link to comment Share on other sites More sharing options...
