My car keeps losing battery. Replaced battery, still dies.?

"I have to start up my car everyday at least once a day to make it to next day."

Dude, you got a battery drain. Take it to a real mechanic, not those dummies at the parts stores. They won't be able to help you.

Look at your quote up top. Your alternator is working. That's why starting it everyday keeps it going.

loglog84, Have you recently had anything installed, like a stereo or some other electronic device, does the car crank slowly when you start it with a fully charged battery, have you checked to see if there is a breaker or fuse that is marked for the charging system in the fuse box under the hood of your car, have you looked to see if the altenator belt is on and tight? I know all of these may seem like silly questions, but as a mechanic, they are all relevant to the problem. 30 years ago, cars I worked on had charging problems, but were usually diagnosed as some other problem than the altenator. Something wired backwards on a radio for instance, or the starter may be going bad, causing the battery to be drained quicker because of the additional load of the starter dragging. Many of todays vehicles have a breaker or fuse that is designated for the charging system, if it's possibly a breaker, swap the breaker from one of the other positions to see if it will help your charging problem, however, be careful of the one you use, you don't want to use the one for your wipers, and then run into a rain storm. But before you do anything else, first check the belts on the engine and with a tug on them make sure they are on and properly tighted. You might be suprised how many people overlook this simple thing (including myself). If all else fails, take the altenator to a parts house to have it tested. Good luck, and have a great day!!

Alternator

well lets talk about your piece o, I'm gonna start by telling you you need to think like a mechanic, time for a break, just kidding presuming you purchased a new matching size battery you are indicating an abnormal battery drain from a constant voltage soarce. many if not most your car is completely powerless with the key off, when you turn the key toward ign or acc they recieve voltage. what uses constant?

the interior lights, the ignition switch the head light switch, and the clock or clocks. all have minimal drain unless shorting out. now added stuff say big amps especially if not correctly wired in, allarm systems going bad or again installed wrong, driving lights installed wrong this could cause it. did you have the alt checked for correct out put? I was thinking about your jump start and dieng shortly after your car runs off the alt when its started not the battery

sounds like an alternator. car parts stockest could check it for you.

if you have a few tools, you can replace it yourself.

disconnect the battery cable, negative.

there will be a belt tensioner which keeps the tension on the drive belt.

place a socket wrench on the tensioner and pull in the direction to take the tension off the belt. slip the belt off the pulley on the alternator.

do not completely remove the belt.

there will be two or three bolts/nuts holding on the alternator.

loosen and remove them.

disconnect the wiring harness from the alternator.

remove alternator.

installation is the reverse.

connect battery when you are done.

get the alternator checked. most places will check it for free. The alternator charges your battery while your car is running. if it was bad, the car would be running solely off the battery and bound to die. That would explain the cause of the new battery going south so soon.

If you get alternator checked, and its OK, it may be battery is too small. I had this problem on a old ford. Kept charging battery and replace with same type, Walmart, then one guy said you need larger battery and it worked great then on. Cant help on prices, hope others can.

The alternator is not puting out enuf voltage to keep the battery charged.Almost any auto parts store'll check out the charging system for free. Try AutoZone or Kragen or Schuck's-whoever.

But that's your problem, not the battery, man.

Good Luck!

As others have said, check the alternator.

An outside possibility is that one of the clamps going to the battery is cracked or loose, or the wire going into the clamp is loose. You could have a well-charged battery that is unable to crank the engine - happened to us.

Have the charging system checked. sounds like the alternator's not working
