2. Trickle charging - Wikipedia

   en.wikipedia.org/wiki/Trickle_charging

   Trickle charging. Trickle charging means charging a fully charged battery at a rate equal to its self-discharge rate, thus enabling the battery to remain at its fully charged level; this state occurs almost exclusively when the battery is not loaded, as trickle charging will not keep a battery charged if current is being drawn by a load. [ 1 ...

3. Solar charger - Wikipedia

   en.wikipedia.org/wiki/Solar_charger

   A solar charger is a charger that employs solar energy to supply electricity to devices or batteries. They are generally portable . Solar chargers can charge lead acid or Ni-Cd battery banks up to 48 V and hundreds of ampere hours (up to 4000 Ah) capacity. Such type of solar charger setups generally use an intelligent charge controller.

4. Float voltage - Wikipedia

   en.wikipedia.org/wiki/Float_voltage

   Float voltage is the voltage at which a battery is maintained after being fully charged to maintain that capacity by compensating for self-discharge of the battery. [1] The voltage could be held constant for the entire duration of the cell's operation (such as in an automotive battery) or could be held for a particular phase of charging by the charger. [2]

   A mobile phone plugged in to an AC adapter for charging. 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, current, for how long and what to do when charging is complete—depends on the size and type of the ...

7. Nickel–metal hydride battery - Wikipedia

   en.wikipedia.org/wiki/Nickel–metal_hydride_battery

   A nickel–metal hydride battery ( NiMH or Ni–MH) is a type of rechargeable battery. The chemical reaction at the positive electrode is similar to that of the nickel-cadmium cell (NiCd), with both using nickel oxide hydroxide (NiOOH). However, the negative electrodes use a hydrogen-absorbing alloy instead of cadmium.
