car battery troubles

Right, all of a sudden my battry is playing up, in the morning it wont turn tue engien over except with a battery booster cliped on, once started in the morning it starts fine all day.
I cant work out ( as i am mechanically challenged) if its just the battery gone or if its just not getting enough charge during my 5 mile drive to and from work...
Any suggestions?
hughesy

I've had similar problems in the past. Try checking and if necessary cleaning all the battery connections and the earth straps. Often it's nothing serious.
Pilsbury

Will do, it just seemed odd to me that the trouble started one day with no warning and has been pretty consistant since, about aweek.
I wonderdd if it was down to the short trips t and from work with lights and demisters on just draining more than gets put back in.
I will dig out my battery charger later as well but im currently off with a bad back so csnt face it at the moment...

Driving 5 miles back and forth to work will never get your battery even remotely recharged, particularly in winter with all the extras on.  CTEK do an extremely good battery charger which will also recondition your battery, MX10 is about £90 (from Amazon) so you can leave it plugged in all the time when you are at home. If you battery is 4/5 years old and this is what you have be doing all the time then it may well be on its way out!

Could it be the damp?

Try spraying electrics  with damp start when they are dry as far as i know it dispels moisture.

Battery

You may have had a cell go down or something stupid like the boot or glove box light is on.  
The easiest way is take it to a garage and have the battery tested, its free and quick.  Remember the old battery can be weighed in for scrap about £5.

Winter is battery dieing time   With a modern alternator you battery should come up over that distance, how old is it here most only last about 3 years. as said try charging up overnight then see if it will start. I have a resistace tester that tells me how good the battery is.

Well i took the battery off today, although the connections looked grubby the actual teeminals and inside the conection points were all bright and shiny.
Put the battery on charge and it was showing a pratial charge, it fast charged for about 2 hours and the charger read that it was fully charged but i left it on for another hour, put it nack in the car and she fired up first time, just got to foind out the code for the radio lol.
I will see how it goes from here but i am a little suspicious it was reading partialy charged and only took a couple of hours to fully charge it.
Jopefully its sorted but i have a call out for a spare battery anyway.
Canburne

I would suggest that the battery will need at least 24 hours on trickle charge to fully charge. The CTEK MX10 intelligent charger I mentioned before will go all through the stages on a nearly flat 85amp battery and can take up to 3 days to go into its 'fully charged' state.

I have a CTEC MXS 25 for the tractors an excellent piece of kit.

Well worth the Money.

kwik fit

I was in kwik fit today having a couple of tyres fitted.  They provide free battery checks.

amps

OK, we can eliminate a few circuits first.  My bet will be on the starter motor or a bulb on somewhere.
Its actually simple to find..  Do you have a multimeter , pop it onto amps and make sure the red lead is on 10A.
pull the negative terminal on and connect the multimeter leads to the battery terminal and neg connector.  if you have a problem you will see some amps. poss 1 or 2 amps.  Normal is less than 50mA
Now the fun starts, looking for the parasitic load.
Unwire the starter motor and check again.

Get one of these http://www.maplin.co.uk/p/400mm-automotive-current-tester-max-n48cy
and pull a fuse out at a time and plug this in, you should not have any amps on it.  Or if there is 2 one watch the meter whilst the other pulls a fuse at a time.  Its time consuming but better than paying £30 per hour.  Make sure you find all the fuse boxes there are usually one big one under the bonnet.

Remember give the car chance to reset the alarm and don't turn anything on as all the current is going through the meter.

Have a look at this youtube clip.  He explains it much better than I can explain

PM me and I will give you my No if you need to chat.
Pilsbury

Well i stopped at my friendly garage and had a chat, first point of actio is i am disconnecting the battery tonight and reconnecting i the morning and see if it fires up, the bet is it will.
Then i mentioned the blowers had stopped working a few dwys before this alstarted so the suspision is the rheostat that contrples thst is leaking to earth now, thats about £20 and apparently is located behind the glove box, same place as the lighter fuses that i think went 6 months ago but i havent been able to find.
I am seriously mechinaclly challenged so i really cant get y head round taking engines apart and really woukd rather trust my local garage for stuff like this.
Im happy to try and deal with batterys and simple stuff but i cant do much more than the basics.

ANy News

Any News on the battery?
Pilsbury

Yep it was knackered, went in for a battery test and it was an absolute fail so i bought a new battery and nooked it in to get tye heater and lighter socket sorted.
Even the garage owner was a bit surprised since it didmt act like a dead battery but it turns out it was the 12 year old original one so £50 doesnt seem to bad.

12 year old  

Been reading up on battery chargers etc. Found out few years ago the makers changed the make up of them so older chargers and some car chargers can't charge them up properly as only use 13.6 volt and now need 14.8v to charge so a dead battery can be brought back to life by charge up some times. Most modern cars have the right charging system. Have just bought new charger  
cold comfort farm

All fixed I guess now the battery has been repalced.
Pilsbury

Well yes and no, the new battery sorted out the starting problems but it wasnt the rheostat for the heater that had gone but the whole blower motor had seized so £160 in parts plus labour its all fixed and working again.....
sod

Great it is fixed but why does it always has to be the exspensive bit  
12Bore

Ouch!
12Bore

Just had to get a new battery for Mrs 12Bore's Micra, £65 fitted at Halford's.
I wonder if this one will last 13.5 years like the previous one?
12Bore

My battery died whilst I was at work, Green Flag arrived and got me running within 20 mins of my calling them  
11.5 years, 79000 miles, can't complain at that.
New battery ordered from Halfords, £52.99 inc fitting booked for tomorrow morning.
Pilsbury

That time of year now though, lots of power needed to get things warm enough to start but even now I still turn my key, watch th light for the plug heaters to go out, turn off and redo and then a third time before I try and start for the first time.
12Bore

Been iffy for a few weeks, was just hoping it would last til the New Year, ah well...  
sod

11.5 YEARS even with your cold winters that is fantastic. Is it a diesel?
12Bore

Nope, 1.6l petrol
