    A 20-volt level was added in a revision named "class B" of the specification. [12] [13] The voltage range of the successor Pump Express Plus 2.0 is between 5 volts and 20 volts, with 0.5 volts steps. The Quick Charge 3.0 protocol supports finer-grain voltage levels with 0.2 volts steps and has a lower minimum voltage of approximately 3.3 volt.

    Most manufacturers claim that overcharging is safe at very low currents, below 0.1 C (C/10) (where C is the current equivalent to the capacity of the battery divided by one hour). [23] The Panasonic NiMH charging manual warns that overcharging for long enough can damage a battery and suggests limiting the total charging time to 10–20 hours. [22]

    en.wikipedia.org/wiki/Nickel–hydrogen_battery

    A nickel–hydrogen battery (NiH 2 or Ni–H 2) is a rechargeable electrochemical power source based on nickel and hydrogen. [5] It differs from a nickel–metal hydride (NiMH) battery by the use of hydrogen in gaseous form, stored in a pressurized cell at up to 1200 psi (82.7 bar ) pressure. [ 6 ]

  5. Battery charger - Wikipedia

    en.wikipedia.org/wiki/Battery_charger

    A battery charger, recharger, or simply charger, [1] [2] is a device that stores energy in an electric battery by running current through it. The charging protocol—how much voltage , amperes, current, for how long and what to do when charging is complete—depends on the size and type of the battery being charged.

    en.wikipedia.org/wiki/Battery_balancing

    Battery balancing and battery redistribution refer to techniques that improve the available capacity of a battery pack with multiple cells (usually in series) and increase each cell's longevity. [1] A battery balancer or battery regulator is an electrical device in a battery pack that performs battery balancing. [ 2 ]
