2. Nickel–metal hydride battery - Wikipedia

   en.wikipedia.org/wiki/Nickel–metal_hydride_battery

   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] Duracell further suggests that a trickle charge at C/300 can be used for batteries that must be kept in a fully charged state. [23]

3. Nickel–hydrogen battery - Wikipedia

   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. Rechargeable battery - Wikipedia

   en.wikipedia.org/wiki/Rechargeable_battery

   Rapid chargers can typically charge cells in two to five hours, depending on the model, with the fastest taking as little as fifteen minutes. Fast chargers must have multiple ways of detecting when a cell reaches full charge (change in terminal voltage, temperature, etc.) to stop charging before harmful overcharging or overheating occurs.

6. Rechargeable alkaline battery - Wikipedia

   en.wikipedia.org/wiki/Rechargeable_alkaline_battery

   The first generation rechargeable alkaline batteries were introduced by Union Carbide and Mallory in the early 1970s. [3] [5] Several patents were introduced after Union Carbide's product discontinuation and eventually, in 1986, Battery Technologies Inc of Canada was founded to commercially develop a 2nd generation product based on those patents, under the trademark "RAM".

7. Electric battery - Wikipedia

   If a charger cannot detect when the battery is fully charged then overcharging is likely, damaging it. [62] NiCd cells, if used in a particular repetitive manner, may show a decrease in capacity called "memory effect". [63] The effect can be avoided with simple practices. NiMH cells, although similar in chemistry, suffer less from memory effect ...
