Doesn't actually matter about the shape of the battery as long as it's 
the same type - read the label - and the same voltage.

If it has a NiCad on board it may need charged before you fit it, to 
avoid clobbering the usually fairly mickey-mouse charging circuits that 
synths have.  If it's a lithium battery it will just have a diode 
feeding power to the memory chips.
