The 41 may not care whether it gets flat or button top cells. But you charger will. ;-)

Using the adapters above, the charger makes contact with the adapter, not the battery. The adapter has a "contact" installed which has a shaft about 1/8" in diameter that makes contact with the battery. So the adapter will work fine with either button or flat top cells.
