Wow, I can only suggest to replace the battery if you have not already. Have alternator tested to ensure proper charging of system. I have not heard of repeated post breaking issues before in one week.

You have a serious battery issue...highly recommend that you have a shop take a look at could be your alternator is overcharging but a shop will be able to verify this.
