none of these questions showed you read the post..simply a dead battery. Im not going to say how it was connected because its all normal..No my meter is not bad. Stop it..

They charged it and said it was bad, IT WASNT..I charged it myself and it was fine..Fine means fine, you dont need details.

But after sitting months it was dead again. No surprise..its usual for a car sitting without driving to go dead..Then they charge it IN REVERSE and Yes this is possible and it held 11 volts with negative as positive..

I installed it not knowing!! Then when I went to charge it myself because of course the car did not start!! I discovered the reversed charge..

Ive totally discharged it and now have it charged properly and it holds charge..And you need no fault designation such as bad cell or whatever..these auto parts shops are not capable of this diagnostic..They just hope to sell batteries. Doesnt matter..

We could discuss potential faults in the electrical system but thats not my question and I can research that in known information..And the battery may not be prime but it holds a strong charge for weeks, but not for months in a stored car..I think its actually been a full year! It should have and could have been charged but they charge it BACKWARDS and it held 11 volts with negative positive..No it goes without saying I did not connect it in reverse, thats impossible given the battery box and cables..no aliens and no way to test each cell and this is all just irrelevant..bad questions because you clearly know nothing about this, as I did!

If someone KNOWS anything about this or the potential damage to the car from putting a reverese charge into the electrical system, THAT would be apprecicated..(you forgot to ask what brand of battery or other irrelevant nonsense) Dont you want the make of my meter and year of the car?? What color it is??

Anyway its a fascinating potential this is even possible..for anyone really interested..Hope it helps someone who is curious and interested..
