Balancer mechanics
Balancers are used to evenly distribute items over multiple belts or multiple belt lanes. Belt balancers are usually used to even out production by placing them in front of large machine arrays with mutiple input belts. Belt balancers are also usually used to balance mutiple belts before or after train stations. Lane balancers are usually placed after production to ensure that a belt is fully compressed or before consumption to ensure that both lanes of the belt are evenly drained.
Lane Balancers
Input Unbalanced, Output Balanced
These balancers evenly distribute the items onto the output lanes but do not "pull" evenly from the input lanes when the output is backed up. They are input unbalanced.
The last balancer is a special case, it only works when there are items on only one side of the input belt.

Input and Output Balanced
These balancers evenly distribute the items onto the output lanes and "pull" evenly from the input lanes when the output is backed up. They are input and output balanced.

Belt Balancers
Theses belt balancers are all tested to be input balanced and output balanced. Throughput under full load and min throughput with all combinations is also tested, it is stated when that is under 100%. Test tests are done using this handy tool by d4rkpl4y3r on the Factorio Forums.
