I have just received two brand new DJI MA IF batteries from a reputable UK stockist.

I have noted that both of these display a production date of 2018/02.

One battery has charged without issue, the second will not power on or accept any charge. It is DOA.

I have contacted the company and they have issued an RMA and will return the battery to DJI for inspection, advised 2-3 week turn around!

My query is with the second battery.

If they were both produced within the same month and have been sat with a vendor for long enough for one of them to discharge to 0% and subsequently fail. How confident can I be that the second battery has not suffered any form of degradation and will not fail in the future, whilst charging or during flight?

Any advise is happily received..
