H5 Posted January 10, 2010 Posted January 10, 2010 Right, after having been a bit smug about the Zed being in the garage during the snow and ice, it appears an error has been made along the lines........! The trickle charger has been connected to the wrong terminals (+ve to -ve and vice versa). I would guess it has been like that for a good couple of weeks. The battery is of course flat, but the charger itself was not 'on' (no light on). So have I fubar'd the battery? Quote
H5 Posted January 10, 2010 Author Posted January 10, 2010 As in it is flat flat. It is a deep cycle battery (well, as deep cycle as Halfords go, it's not Yellow Top), but there's nothing, not even a window drop. I have reconnected it the right way and the trickle charger is at least on now....... Quote
rtbiscuit Posted January 10, 2010 Posted January 10, 2010 its a wait and see job i think. its likely to be damaged but how much i don't know. you may find it will hold its charge and all you did was just reduce its life slightly. charge it over night or until you get a full charge, then start it, turn off and leave for a couple of days not on charge and try starting again. 3 days should show any signs of draining. if the battery is fine it will start no problems. if its FUBAR then it will struggle.

Husky Posted January 10, 2010 Posted January 10, 2010 depends on the trickle charger really, if it has built in protection against it? if it does, it means your battery is flat just in the same way as if you didnt have the trickle on Quote
ZMANALEX Posted January 10, 2010 Posted January 10, 2010 If the trickle charger does not charge the battery due to it being totally flat then best to remove the battery and hook it up to a proper charger at your local garage. Sometimes this is required just to kick it back into a chargable state. Quote
H5 Posted January 10, 2010 Author Posted January 10, 2010 So will give it overnight / 24 hours to see if it charges and go from there then....... It was a new battery just before Xmas too! Quote
Beavis Posted January 10, 2010 Posted January 10, 2010 Dear me 2 wires Rob, red and black I only have about a 1000 to get right this week on a rewire job Quote
H5 Posted January 10, 2010 Author Posted January 10, 2010 Dear me 2 wires Rob I only have about a 1000 to get right this week on a rewire job That's why you're an electrician and I'm not...... Not allowed to be either being colour blind!! Quote
dcash5 Posted January 10, 2010 Posted January 10, 2010 Rob most trickle chargers will have a polarity check aswell - so should be safe. As suggested before whip it off and take it to somewhere that has decent equipment Quote
H5 Posted January 10, 2010 Author Posted January 10, 2010 Yeah, it definitely wasn't charging so shouldn't have caused damage itself. Hoping it charges and holds now. If not by tomorrow I'll get it on the unit at my Dad's work Thanks chaps! Quote
H5 Posted January 18, 2010 Author Posted January 18, 2010 Been on the trickle charger for a week now and it's still pretty much dead (nowhere near cranking capacity!). Will a big beast of a charger be able to kick it back into life? Am such a donut! Quote

Will a big beast of a charger be able to kick it back into life? Am such a donut! usually when batteries go past a point thats them damaged and gone im afraid Quote
yokomo Posted January 18, 2010 Posted January 18, 2010 if its had a week id have to agree with the doggy and say its time get that yellow top Quote
speedy Posted January 18, 2010 Posted January 18, 2010 Would say it dead, like are a bit like a spring/elastic band once they go past a point they dont return..... Quote
ZMANALEX Posted January 18, 2010 Posted January 18, 2010 Will a big beast of a charger be able to kick it back into life? Yes, definately worth a go. Nothing to lose. Trickle charges will not restore a really dead battery. Quote
Mark@Abbey m/s Posted January 18, 2010 Posted January 18, 2010 1 thing that may work , turns the lights on or turn the interior light on , this will load the battery enough to make the charger work , sometimes helps recover a battery. Quote
H5 Posted January 19, 2010 Author Posted January 19, 2010 Cheers guys - will try a last ditch boost / light turning on and see if it wakes. Otherwise it's another £100.... Quote
Husky Posted January 19, 2010 Posted January 19, 2010 for next time... BLACK RED hope it get sorted and you dont have to fork out again Quote
H5 Posted January 19, 2010 Author Posted January 19, 2010 I know!! Will get it sorted. Silly thing is, for years I have had chargers on my cars for the audio competitions and had the big deep cycle batteries etc, and not once. Now, I seem to have forgotten the difference between +ve and -ve!! Quote
