Not really a question about Dick Hannah. But if you have installed any aftermarket electronics, you should disconnect them and see if the issue goes away. If the battery was fully drained even once, you should replace it.
Are you leaving lights on overnight? Is there a third party tow package that might be grounded out and causing your battery to die? Did the battery start dying recently or were there considerable periods of time between when they died?
Check to make sure all your lights are off and all doors are closed while parking. You may be draining the battery inadvertently. Also try to limit short trips less than 15 minutes. The alternator will start charging the battery after 15 minutes of the engine running. Take it to an auto parts store. They can check it for free there too. Second opinions are always good.
The problem might not be with your battery. It sounds like you either have an accessory on all the time that is draining the battery while you are not using it such as your dome light. Or there is something wrong with your alternator and it is not recharging your battery like it's supposed to
If you are sure you haven't left lights on, Sounds like a parasitic drain on the battery. If you have installed any aftermarket electronics in the car, unplug them to see if the issue goes away.
