Most devices & gadgets are rechargeable nowadays. The only thing I have that still requires batteries is a headlamp but even those are available in rechargeable varieties. House smoke detectors need a battery too.

Are you trying to charge a lithium primary? That seems… unwise.
If this charger is like my NiteCore, it can charge each of the 4 banks individually.
Yes, this looks like a dual-chemistry slot charger that handles both NiMH and 3.6/3.7V Li-ion, which would charge each battery independently.
The battery in the third slot looks to be an Energizer L91 lithium-iron-disulfide primary battery. Those are not rechargeable, and attempting to charge one may cause it to explode.
