Depends on the battery. Some batteries use extra contacts for extra functionality/protection.
Also, be aware that very few chargers that are made for cylindrical cells, also have the possibility to connect external temp sensors. A temperature sensor will allow you to do safer charging (I'd recommend that with dV/dt charging). I have a recollection of the MC3000 supporting it, but can no longer find proof of it. So you may be better off with other chargers or go DIY.
