Battery charging methods and associated chargers which are capable of rapidly charging a battery while subjecting it to reduced levels of overcharging. The methods described are capable of being utilized within numerous battery charging systems for batteries spanning a range of chemistries, such as lead-acid, nickel-based, and lithium-based batteries. Upon detection of the onset-of-overcharge during the charge process, a variable voltage lid is imposed (VLID=.nu.(.phi.)+.beta.log.phi.+.kappa..phi.) which reduces the maximum voltage that may be applied to the battery as a function of charge acceptance which is typically estimated by a calculation based on state-of-charge. Additionally, the voltage lid can be approximated with step-wise voltage lids which are responsive to the level of charge acceptance within the battery.
