1st thing is there have been some problems with members cars and their batt's/alt's.
BUT..... Also understanding how the charging system works might help since you're draining the batt every morning.
The myth that driving your car will "fully" recharge it an't going to happen, it will charge it to about 80% after 20 min at highway speed(or higher rpm etc.).
The cure is to use a trickle charger......... if you don't have a power source, then buy a solar charger you can plug into your dash, and put the solar-cell on the dash. ***** They work in cloudy conditions as well.*****
I'm sure someone will come on here and explain the batt/alt issue, if that's your problem............ Still doesn't mean you shouldn't get a charger and use it about once a month since you drain it a lot.
Another thing about how our cars work...... When turning the key on, you need to have the hand brake on before you 1st turn on the key, that's so your daytime running lights won't come on, the lights will drain the batt a lot quicker than the sound system.
