ive replaced my battery 3 times this month. i took the alternator out took it to pep boys it charges just fine. ran brand new grounds when i got the 2nd battery. alternator grounds are good also. checked all my fuses they are fine. wth can be draining my battery ?!?!

could be something as simple as a dome light that stays on or lights.

check for the hatch ligth if turn off.. also..i did say take the car to advance auto parts and tell them to check ur batery and alternator again ( without removing the alternator )
or if you want try this.. get new batery.use the car but everytime u shut off ur car. disconnect the battery !if u do that and ur car eat that batery too ..ur alternator is not charging good no matter what! just try that for a few days to see if is a ligth or something else eating ur batery .

my friend is having the same problem,he has killed like 8batterys already..I found out that the alternator is shorting out..it still charges but kinda low( 13.3v-13.4v ). In fact the alternator power wire almost burn my volt meter lead..lol

i dont think its a parasite because the car turned off on my while i was driving. when i floored the car it started to sputter then it bogged up then my headlights turned off then my gauges then it was just a real bad idle then it jus turned off. i jump started it then it drove for like 5 mins super shitty then it jus killed my battery

you can check parasitic drain by removing the negative battery terminal when the car is off and putting a multimeter on the neg. terminal and the other lead on the actual ground cable. Set your meter to amps and see how many its pulling over time. It takes about a half hour

Or just do a draw test w a multimeter first, Jesus Christ.

orrr with a test light, disconnect the positive terminal and put the test light on the battery terminal and one on the positive wire to make one circuit/ the light should be on if you have something draining it. pull every fuse one by one till the light turns off. when you have found that fuse go back and trace everything that fuse is used for. easy.

^^^ Bad diodes can also allow current to leak from the battery back through the alternator to ground, causing the battery to rundown overnight.
