My battery dies in 2-3 days of car not running.

I thought it was because of my 24/7 dash camera, well, I turned it off and still have the same problem.

I replaced my battery couple times now and did full alternator test (this is aftermarket alternator).

So seems like something draining the battery, anybody had similar problems? any suggestion?

More than likely it is the alternator.

I'm assuming that battery terminals are good (as in no corrosion, etc.)?

Yeah, terminals are good.

Whats also weird is that when I jump start the car it runs good, so it seems like alternator working fine.

it does sound like an alternator, but i think the battery would die faster than in 2-3 days with no juice while running.

edit: misread original post, didn't realize the car wasn't running.

Yep, only way it would be alternator is if its actually drains battery when the car is NOT running

sound like you could have a short somewhere, if you have done any mods that tap into electrical I'd start there.

I have switchbox (all switches were off) and amp for subwoofer. So only thing that comes to mind would bad amp? But I never noticed it been hot when car is off.

Honestly don't do what I did... Get the car running good and take the alty to get it tested. From what I gather your alternator work intermittently until it leaves you stranded. My car has had three altys that I know of.

Here is a great link i found:

So I am off to buy tested and look for drainage

If you have jump started your car, you must try to fully charge it, otherwise it will just continue to die faster. Running it 10 minutes on your way home is not a long enough time to recharge it. It's not even long enough to refill the energy needed to start the car. The battery will just die again.

The good news is lead-acid car batteries are VERY resilient. I'd pop off the caps and check the water level. Add distilled water only. No salt, not even sulfuric acid... just distilled water. Then surprize your loved ones and drive somewhere on the freeway for 1 hour and take them out. That two hour drive back and forth should get you close enough to a full charge.

I just had a similar problem - get the charging system checked for free at a place like Autozone. Also, if you want to see if the alternator is working - disconnect the positive terminal from the battery while the car is running. If it stalls, the alternator is unable to supply the electricity for ignition, meaning time to replace it. While I was replacing my alternator, I put the battery on a slow charge. When all was assembled it started right up.

take a dmm and test the wires at the amp...make sure the amp turn on aka remote wire turns on and off when its supposed to. also check to see if your ground is good on the amp. its a possibility that the amp can cause a drain, if it is shot or going bad, it can cause an excessive draw. do the same with that switch box, it has to get power to distribute it, so make sure the connections are ok and not oxidized if its hardwired to your car. take the battery out and have autozone etc do a load test on the battery to see if its good, you should replace your battery about every 5 years. in FL, you guys got some serious heat which affects batt life as well, with a/c on etc.

also the amp shouldnt be super hot. if it burns your hand to the touch then your amp is bad, or your demanding too much from it and its stressing it out. this can cause problems too. you can take the fuse out by the battery for your amp for a few days and not power the amp to see if it is this as well. no beats, but its an easy way to test.

I also have two flasher modules. They get constant power and trigger wire. I think thats what drains the power. I'll fix it and will see if it will help. I will use trigger wire for constant power and for trigger. So it wont get any power when car is not running.

use a relay to connect your modules or whatever else you have aftermarket wired in your car to turn on with. maybe they are drawing too much from the source of which its connected to

pahanorlando

Yeah, the flasher module was supposed to work as a relay, but for some reason it was constantly drawing power from my battery. I fixed it by using trigger wire for trigger and for constant power.

If someone interested in what I am talking about, here is the manual with wiring

As you can see, it gets constant power and trigger, but still drains battery. Looks like they messed up with their product.

unless you use whatever is connected to the unit with the car off, i'd tag it to a switched ign/accy source so it turns on and off with the key

I use strobe lights when the car is off too, so I just tagged it to the switch (acc+constant power)
