Dead Battery I have a '93 Accord wagon and have been having problems with keeping the battery charged. I have even put in a new battery and new terminals but the battery is now drained. What could be causing this.

Have the alternator checked , not charging .

The starter probs needs to be changed, I ask has it done it even with the new battery, if so then ist your starter, if not then your charging system isn't charging the battery properly, hope this helps

Lead acid batteries don't like being discharged flat, and it could now be damaged and unable to hold a charge. It does sound as though the voltage regulator part of the alternator is allowing discharge to ground when it should not. You would seem to have a good warranty claim on the battery given they did check the alternator and pronounce it OK.

your new alternator is defective ,disconnect the cables to the alternator and see if the battery goes flat then

The battery may not be holding charge. If you drained your battery a few times because of a bad alternator, it is possible to destroy the cells in the battery causing one or more of them to no longer hold a charge. Most batteries are manufactured to be cycled or completely drained 8 times. Other factors such as excessive load and age can decrease that number. You may also have a faulty voltage regulator that can result in overcharging and destroying the battery. Charge the battery on portable charger and have it tested. Also, It is possible that since most alternators are rebuilt they can be bad out of the box.

sounds like the trunk light switch may have gotten knocked loose .. that would leave the trunk light on all the time and would run the battery down in a few days even if fully charged to start with .. you can take out the trunk light to test that theory .. the alternator will only put out what is needed and thats probably 30 amps with everything on .. to test its maximum capacity you need to hook up an external load and you have to run the engine at a specified RPM ... for a quick test.. if your alternator maintains about 13.2 volts at idle with everything turned on .. then its gererally working ok ..

buy a cheap volt meter check voltage on both sides of the starter seleniod on the fenderwell if you have 12 volts on both sides while cranking test voltage at starter if you have 12 volts at starter with fully charged battery and it doesnt start you will need a starter it also sounds like you might need an alternator once you can get it started

you are having a problem with your alternator. the battery has a main purpose to start the vehicle, keep computer memory, and give power to electrical components when the key is in the on position. the alternator charges the battery and gives power to electrical components when the vehicle is running. now when you hit the brakes there was an extra load added to the alternator and if the car died then the alternator is running very weak and needs to be relace.

Was the battery checked before it was sold to you? Batteries will lose their charge over a period of time even when not hooked up. If you have a voltmeter it should read 12.8 volts on a fully charged battery.
Have you tried to boost the car with cables?
I suspect if the car was working OK 3 months ago it should start. Which leads me to suggest an undercharged battery.

It could be a multitude of problems, however the first thing I'd do is check that battery.

A lot of times, batteries just get wore out and even while being charged; they aren't able to help keep the system stable enough. Even with the alternator pushing out the right amperage, it may actually be causing more problems as it's not holding enough of a charge. Usually when the battery is fully charged the alternator will only power the vehicle itself while not charging the battery.

I'd try the battery first, then look into the wiring off the alternator. Also check for bad terminals, wire connections, or even corrosion on a ground contact.
