I tried staring my car today, it cranked over a bit, then the power went out. Seemed like a dead battery. I tried jumping it with my wife's bmw, it did the same thing... Tries to crank then power completely goes out

I haven't driven my car much since June. Last time I stated it was about a month ago

Is my battery completely dead?

are you jump starting the battery from the frunk or engine compartment?

Yes, it's likely your battery is dead or at least it needs to be recharged.
Try jumping from the engine compartment using the "+" terminal and the ground bolt in front of the airbox with the donor's car engine running and rev'ed to 2k rpm.

I tried jumping from the front, I will try from the engine compartment when I go home tonight - Thanks

I'd take the battery for testing before I continued trying to jump it. If the battery is OK, something else is making the car hard to crank...

ODDS ARE that the battery is bad, but it doesn't cost anything to go have the battery tested at Autozone...

You have a drained battery. Give it a good change (24hrs) and try starting the car again. The engine might be a bit flooded now but probably will dry out by the time the battery is charged. Don't try jumping or boosting it. This will put a very heavy load on the charging system and can shorten the life of the alternator.

The jump did not work at all, will charge the battery this weekend

If a dead battery sits for more than 3 day, hardly ever will it recharge and bee good again. Charge it asap. Don't wait for the weekend unless you have no other choice

I'd not waste time trying to recharge the battery. Just replace it. The car has sat long enough the battery has gone flat. Lead/acid batteries do not do well once the have gone flat. Even if you manage to recharge it the battery will never be the same.

Save yourself some trouble and replace it with a new battery of the proper size/capacity.

Then make a note to yourself to drive your car more often and long enough to recharge/replenish the battery after the engine start.
