The only batteries it makes any sense to refresh/restore are NiCd and possibly NiMh. The only thing you will do with Lithium cells is use up life. With NiCd if they are stored for long periods of time, or they are repeatedly only partial discharged, it is possible for the micro-crystaline structure of the chemistry to aggregate into much larger crystals, greatly reducing the surface area available. So while the actual total capacity remains the same, the usable capacity can drop dramatically because the available surface area is main factor in internal resistance. One you reach the usual discharge point, the sudden decrease in surface area cause a large increase in internal resistance, giving the appearance that the battery is discharged. It is only by fully discharging a cell with this problem,and then re-charging that the problem can be rectified. In addition, many NiCd and NiMh need a certain amount of 'break-in' to reach full capacity. These are issues that are quite specific to NiCd and NiMh batteries. The only thing these features are potentially useful for with Lithium cells is measuring actual capacity, there is nothing to be gained for doing so in terms of cell capacity, but Lithium cells generally are good for many fewer cycles than NiMh or NiCd cells, so you end up using up lifetime when you use this feature. In short, these features are generally only useful if you plan to use NiCd or NiMh cells.
