If in the US or Canada, take your car to one of the chain auto parts stores for a free battery test; I would do this first since there are problems that may be draining the battery slowly or the alternator can be defective and discharge the battery while standing. The alternator can also be checked at the parts store and they will tell you (if not, ask) what series battery you need.
If you have a multimeter (they are under $20 US) or know someone who has one, it makes sense to check for current flow with all electrical items and the engine off, the battery charged. Disconnect the black (ground cable) from the battery and measure current on the separate, normally present, 10 Ampere range by connecting the positive (red) lead of the meter to the removed negative cable and touch the negative (black) meter lead to a clean chassis point. Since there are items that draw small amounts of current even when appearing 'off,' some current may flow but typically, it should be under 0.1 Amperes. Clocks, radios and the computer may draw a little even when apparently doing nothing. Anything above 1.0 amperes is not normal for a standing auto since this will drain a battery in 1-3 days.
Batteries vary greatly in quality so personal friends' recommendations help, and I can recommend Interstate brand but avoid the 'green top' series from them since they are very poor. The 'black top' series are among the best and priced in the mid-range.

Wont start after battery change

Check and make sure the battery was installed correctly.
If it is, Check the battery to see if its charged and working. You may need to purchase a new battery.
Another issue may be that you have the wrong battery for your particular vehicle. Check in the owners manual or go to a parts store for information on the battery type.
Thank you for usin FixYa.

I have a 2003 Oldsmobile Alero, the alternator and battery has been replace however the battery will not hold a charge.

If the alternator has output on the car and the battery is not being charged look for a faulty fuse or fuseable link between the two.
You would check the output of the alternator first.

Rpm gauge stops working and altenator stops chargeing

Thanks for choosing FixYa and welcome to the site. Your alternator is part of the charging system. Make sure your battery is good and holding a charge. Make sure you see no fluid leaks on the battery. Make sure the terminals are cleaned and they are tight to the post. Here is how to check your alternator to see if it needs replaced. Start your vehicle and then take the hot side battery terminal off the post. If your vehicle dies instantly, your alternator is bad and will need changed. If it doesn't die instantly, recheck the battery, wires, and terminals. Make sure the alternator wires are correct, tight, and not damaged. If you have any questions, feel free to ask. Thanks for using FixYa and have a good day.

Battery does not seem to be holding charge. 6 year old battery Will be jump started no problem and starts all day but no chance the following morning Thanks

Sounds like the battery can no longer hold a charge and needs replacing but first have the alternator checked to make sure that is putting out a charge to your battery, most garages will do this test free of charge for you
Hope this helps

I boost the battery, and it does hold a charge but only for a day or a day and a half at most. I'm not sure what could be causing this problem. The battery was purchased Last year brand new, but sat all...

if the battery holds the charge for a day or 2 wile you drive the car normally then you should check your alternator live the car 2 or 3 days after the battery was charged and check if it starts and run if it does run it another 2 or 3 days and see if the battery dies if it dies most likely your alternator is bad, your mechanic can test it with in 3 minutes to see if it is the alternator or the battery

Is there more than one type of replacement battery for this car? i purchased one at autozone by asking for a replacement battery for a 95 buick lesabre. just want to make sure there is not more than one...

there really is only one physical size that will fit the space. but there are different levels of power that have to match your car. ideally replace the battery with one the manufacturer recommends or higher. what you looking for is (cca) cold cranking amps

After changing alternator and voltage regulator. Still not charging. 2nd $15.00 regulator replacment

Check your battery and check the ground wire from battery. Make sure all your wires are clean and good connections. A bad battery will not charge and a dead battery will not charge a alternator maintains a battery not charge a battery, so charge your battery completely before checking that the alternator is working. Check all the wires going to the starter for good tight and clean connections . Hope this helps...

1999 Volvo S80 will not hold a charge

Tricky ... Was the alternator replaced with a 2nd hand one or a new one?

A defective alternator can allow the battery to discharge within a few minutes (the diodes in the rear of the alternator can burn out and cause the problem. The diode pack can be replaced). When this happens recharging the battery only replaces the power in the battery - which drains straight back to earth via the alternator, flattening the battery again - often within a couple of minutes or less.

Does the battery lose its charge when the car is standing or just when the engine is fired up?
If the battery loses its charge overnight, try disconnecting the wiring from the rear of the alternator (also look at the electrical connector that fits into the back of the alternator - look for melting/burning marks which suggest something may be amiss inside the alternator).

Let the car stand overnight with the alternator wires disconnected. Will it start up ok and drive (with the alternator wires still disconnected) the next morning?

You could also try just disconnecting the alternator wires, firing up the car and then driving it -
If the car drives ok without dying out and gets further down the street than it usually does, then it probably is the alternator at fault. The car should drive until the battery drains and has insufficient power to trigger the ignition. You certainly would get further down the street with a charged battery and disconnected alternator than you currently do.

It does sound as though you've had an alternator fault to begin with. If it has been replaced with a 2nd hand unit that unit may also be faulty. Rather than replace parts in desperation, visit an auto electrician's - within a few minutes they will be able to test the battery/alternator output and also identify where the lost current is going. It will be cheaper in the long run to have an auto electrician look at the charging system. It only takes a few minutes.
