I assume like li-ion they use a CC/CV charging scheme - that's Constant Current/Constant Voltage. The batteries are charged at a constant rate of current until the voltage rises to a set maximum, then tapered off to maintain that voltage. The first 80% or so of charging takes place during the constant current portion. Furthermore multi cell batteries require a battery monitoring system that balances the individual cell charges as capacity and charge level may drift as the battery ages. This can also add a small amount of time to the final charging.

So because the current to charge to that point is no longer constant and the curve is relationship is no longer linear after 90%, giving the total charge time would be misleading when comparing usable capacity across chemistries - you don't have to charge them to 100% every time you use them. In fact If the goal is to swallow up energy as quickly as possible you wouldn't want to.
