charging the battery

Have`nt moved my car for about 6 weeks, thought i would take it out today, now this is the fun part car started after a couple of attemps woop i thought, the problems started when i got back home the key fob would lock the door but not open it made a whinning noise, so of to the local wilco`s to get a replacement battery for said fob, nope still doing it has the car battery gone kaput or could the alternator gone kaput, the battery does`nt seem to take a charge now. would a decent run out down the motorway help sort the problem or am i looking at replacing a, the battery or b, the alternator. any advice will be appreicated.

the car sounds like the battery is dead but then it will turn over and give me enough juice to start, its a rover 25 tdi diesel.

first of all be careful with the radio because if you take out the battery and you don't havethe code, you will be back here looking for codes - more trouble

secondly it just sounds like the battery is completely dead, a battery pack or jump start will get you going and a good spin should charge the battery.
also most garages have a battery tester to tell if the cells are gone in the battery if it does not take a charge
if your alternator was going well before the car became idle i would'nt think there would betrouble there, hopefully.
hope this helps dee

i`l take apound to the garage in the morning first, think it needs a good old run out to get a decent charge but will have it looked at.

How old is the car dee?
Most batteries only last about 6 or 7 years, then the cells start to die inside the battery and they won't take or hold a charge after that.
Get it tested at the garage and take it from there, doubt it's your alternator if it was you would have a warning light coming on.

batterys about 3 years old was fine before i left it standing.

Pretty sure it's fine then, as you said it just needs a really good charge.

I agree with the lads, get it tested. The reason it has run down could be that you had the alarm on for the last 6 weeks, which will run the battery down, in which case a good run down the motorway is all you need, or borrow a battery charger.

i will get it tested if alls well i`l take a trip out tomorrow.

diesel car are hard on batteries.you may find later you will need to replace it.

when we bought Georges car battery was a bit iffy sometimes it would start and other times it would do nothing. someone told me it might be the alternator, but no warning lights came on. Decided to take it to a garage, rather than test the battery we opted for a new one at aprox £40 Corsa 1.2 sxi 52 plate. Car had been garaged for some time so battery just died. After new battery are works like a dream! we were told to charge battery car would have to run for at least an hr or so ( waste of petrol) so cheaper in the long run to get a new battery than keep testing and running car to see if it will charge!
