I just bought a NH-14WM(A) battery to replace my NH-10WM that came
with my MZ-NH900. However the new battery has half a charge and I
can't recall if I am supposed to drain it and then do a full charge or
charge it up the rest of the way and use it. If I remember right if
you do it wrong it can mess up the amount the battery can hold. Can
someone tell me the correct thing to do?
Thanks!
