sometimes my car just doesn't want to start even if I've left it on a charger all night. Someone can give me a jump and it starts right up. Something is draining my battery in such a short time.

any electronical devive left on, or the battery has a liquid in it sometimes it runs low.

tell us about the. it could be somethin about the , add ons, or you being a doof (no afence).

tell us about the car. correction to my last post.

Its your alternator needs to be replaced asap

I believe in your case just replace the battery, but in the future if you want to know if you have problems in your charging system; this are the steps: 1. Check how many volt your battery have a cheap volt meter does the trick and it have to read 12.6 volts if it read less before replace charge it on a auto parts store (It's free). 2. With the volt meter and someone else just see how many volt goes down the battery when you crank the car if it goes lower than 9 volt your battery is going bad. 3. When the car is on read the charging cycle on the battery if it fluctuate (the reading goes up and down to quick) your alternator is bad or if it charging less than 12.9 minimum. Knowing this I do recommend to get that volt meter it can save you to pay extra money on any auto shop when it is simple stuff.
