Waste-time during charging (Bantam Chargers)

[BrianG]

Maybe it's just a safety feature then that makes sure the difference between charge and float voltages aren't too high. Kinda like if you were to charge a AA NiMH at 5A. The voltage would increase to over 1.7v, but the resting voltage might be 1.2v. This 0.5v difference would be a red flag to the charger that it was set too high and set off an alarm or auto-reduce the charge current.
