New 3700mAh batteries

[Elliott Hopkins]

Assuming that 3700mAh batteries haven't been matched by most companies for a while, would a pack of matched 3700s that have been sat on a model shop shelf for a while possibly show any signs of detereoration if they are used? Is there a chance some of the cells might be useless?

I'm preferring the 3700s to the pack of 4200s I have. They are far more robust.

Thanks.

Elliott.
