Answer 1

Something isn't charging the battery, get the alternator (I think thats the name of it) and belt checked.

Answer 2

Three batteries in three months is way out of line. In fact two batteries in three months is out of line too! Warranties do not cover recharging but charging your battery for you should be free. Especially after you've bought three batteries from them!

However, it's obvious you have a problem with your car that is not being properly diagnosed. Simply put, your battery is not recieving a charge and that should be accompanied with a battery light on the dash. The car's alternator supplies electricity when the car is running and keeps the battery charged. The only thing the battery is used for is providing power when the car is NOT running and providing power to the starter to start the car. After that, it just sits there while the alternator does the rest.

When the electrical output of the alternator is less than the battery, the battery starts supplying power to keep the car running. At that point, the light on the dash should light telling you of a problem with the charging system. I've seen alternators fail and they still didn't light that dash light so just because you don't have that light doesn't mean the alternator isn't at fault. It most certainly is.

Here's the sad part... a bad alternator can prematurely fail a good battery and a bad battery can prematurely fail a good alternator! Your very best bet is to drive the car to Auto Zone (or equivalent) and they will hook up a tester for free. The tester will immediately tell you where your problems lie and you can take proper action.

Here's a little more advice... A plug in the wall car battery charger doesn't cost very much... probably around $20 for a no frills one. Keep it in your garage. I ran a car knowing I had a failed alternator for a week with just a full charge on the battery. Of course I drove it during the day when headlights weren't on and I certainly didn't turn on the radio or anything else electrical that I didn't need. I would connect my battery charger, plug it in and leave it charging the battery overnight. I did this until I could arrange for a good price replacement alternator.

Also... you get a better alternator when they come with better warranties. You might think you are getting a bargain when they tell you they can rebuild yours for $80 but I am here to tell you they will only replace the damaged parts and dress it up to look pretty. They hope the rest of the parts will last at least one year which will put you outside of their warranty and you start over. A "remanufactured" one will at least give you one that comes with all new parts. A new one might be the ultimate but they cost serious dollars in comparison and you generally don't need it.

Good luck!

Answer 3

do not replace your battery again
the most likely reasons for your battery going flat are-

(1) the earth lead needs replacing. on modern cars this goes from the negative terminal of the battery to the chassis of the car. You often find that there is corrosion at the point where this lead connects with the chassis of the car. This needs to be cleaned (sandpaper etc) and probably a new earth wire connected.

(2) a fault with your car not charging the battery enough. the alternator sometimes fails. possibly the wires to and from the alternator are dirty or corroded. in order to work properly, everything needs to be clean and shiny.

A car battery should last five years, often longer. It is not like batteries in your radio! If you have been getting a garage to replace the battery, get a new garage.

PS on some cars the battery goes flat because the light in the boot (trunk) is not going out when you close the lid. The easy solution is to remove the bulb.

Answer 4

Couple of questions...does the battery charging light stay on in you in car instrument panel? if yes then it sounds like that is the alternator, next question does you car make a god awful squeal when you start it in the morning? if it does then the prob is a slipping belt, that is cheap to replace...if not then it is most likely your alternator, you can get these at halfords, there are reconditioned units, but you have to take your old one in...and the cost is about £60...however before that expense look at the following...the two lugs on the battery that the clamps are tight and clean..if not then undo them...and clean with emery..note your radio code first as it will need recoding, that the lead that goes to the car body is intact..this is known as the earth strap...and that the connection point at the body is clean..spray with wd40 anyhow..it may pay to take it to a local garage if you feel the job is more than you would feel comfortable doing...the cost of this should not exceed £100-120..batteries these days just die..so its very unlikely to be that.

Answer 5

If your car is diesel and is not direct injection.ie uses glowplugs,then it is likely that your glowplug relay is sticking on.simply and cheaply remedied.

If your car is showing the battery light on the dash at anytime that it shouldnt ,the alternator or contacts to it are at fault.

Starter motor,battery and alternator checks are usually free at all motorfactor supply shops.Use them.

Look for obvious signs of equipment being left switched on after switch off.
If your car has difficulty starting, then excessive burden is being placed upon your battery ,shortening its life.
It is possible that you are making assumptions that your battery has failed when in fact it is another problem.Sometimes , the extra boost from a new battery will temproarily overcome your cars difficulty.
Try using a single jump lead from the negative battery terminal to a clean earthing point within the engine bay.If this starts better then it is likely that the metal braided earth strap is damaged and needs to be replaced for £3.and 10 mins

I suppose advising an auto electrician is a little obvious , but compared with buying new batteries it may be the obvious solution.

Answer 6

Angel, I believe you have a small amperage short in one of the circuits in the electrical system.I had the same problem on a 94 Cutless Cierra.The radio had a low amp short and was not blowing the fuse.If you have a clock radio and the time light does not go out soon after you shut the engine off ,that is your problem. If so, unplug the fuse to the radio and that should cure the problem .

Answer 7

get your local Bosch Car Service garage , they have a BAT121 tester which can check both battery and alternator, under load.
don't spend anymore money on batteries, dis-appointed no-one gave you better advice when the problem first occurred and someone should have picked it up on the 2nd/3rd battery.

Answer 8

I would get your alternator checked as if it is not working then your battery will fail!! look in the yellow pages or if a member of a break down company see if they can help

Answer 9

It is hardly ever the battery, you should look elsewhere for this problem. Something is draining the battery whilst the car is not being used.

You need to get a mechanic to look at this car. Somebody who will do more than just "sell you a new battery".

Please, do NOT buy any more new batteries for this vehicle.

Answer 10

Take it to a garage and have an AVR test preformed, most shops will charge about a half hours labour to check it. its msot likly the alternator, but there could be something else in the system causeing a drain.
