I put a new battery in2 years ago ,it has gon 200miles hardy any short trips.Had it to the garage yesterday they did a battery test ,compleatly dead, keep it over night and ckecked for a draw on the battery, wasn't any, alternater its ok. This has happened over the last 2 months 3 times, I get it going by my battery charger,I do not take short trips as I walk in town .it seems to do this after it sits and not used.
There are no doors open no lites on,and the car is in excellent shape for 33 years old,has been in car shows
I beleive there is a very slow drain on the battery which takes over 10 days not over night
Tank you so much

Battery and Alternator tests good-the only thing I can think off is something is draining the battery and its being caused by a short circuit within the electrical system.
