I have Nissan Sentra 2002. I recently had my battery changed. The new battery died after few days. I went back to the shop and they put a new battery. The new battery died again. I went back again to the shop and now they are telling me that my car has electrical problem that drawn the battery down. My car has no problem before I got the battery changed. So I am wondering if a mechanical mistake in changing the battery can cause electrical problem.

Only if done while battery in car, and still connected to your system.

Sometimes. It is more likely that you have a faulty alternator. They tend to go bad by shutting down when the engine warms up. The result is that when the engine is cold, the battery recharges, When the engine is hot it soesn't charge the battery, and eventually stops charging all together.
Another possible cause is a faulty alternator belt. If a belt get glazed, it will slip just enough to keep the alternator light off but wont charge the battery. Most auto parts stores will check the battery, alternator and belt for free

Check the date of manufacture on that new battery they just sold you.
New batteries have a shelf life of only 6 months. They need to be used within that time. This is because lead acid batteries are already starting to very slowly lose their charge right after manufacture. After 6 months, the chemicals in the battery start to sulfate (collect a sludge) and some of the battery cells start to die off. At first the battery may still have a charge in it but it will refuse to take a recharge.
Be sure to check if you got a fresh battery off the factory less than 6 months old!

Why did the battery need changed to begin with? Chances are they didn't hook something up right when it was changed or the problem existed prior to the battery being changed you just didn't realize it. See if you have a place that can check the electrical and give you an estimate they will generally tell you what is wrong before you agree to having them fix it and it shouldn't cost alot if anything. Good luck!

If the battery terminals were inadvertently hooked up backwards, damage to the alternator may occur. Usually blows the diodes in the alternator. It will not charge with a bad diode.

sounds like your alternator has given up the ghost, go to autozone and have the charging system checked out, the only way they could have done something wrong was to put the negative cable on the positive terminal by mistake and then try to hook up the positive cable to the negative terminal, that would more than likely fry your alternator.

with a car of this age it would be wise to replace both the positive and negative battery cables. it will save you money in the long run from further battery replacements.

I had the same problem with my car. It kept dying everytimeI would cut the car off and it turned out to be the battery cables.
I changed them both and no more problems
