Trickle charging is used to make up for the capacity loss caused by self-discharge after the battery is fully charged, and pulse current charging is generally used to achieve the above purpose. To compensate for the self-discharge, the battery is charged with a continuous small current that keeps it in an approximate fully charged state.
Trickle charging refers to the third charging stage of the battery after rapid charging and continuous charging, after the first two stages of charging the battery, although the power display 100% or has turned the lamp, but in fact the battery has not really reached saturation state, at this time the remaining capacity can only be supplemented by a small pulse current, the battery can really reach a good state of saturation.
trickle charge means that the charger automatically switches to trickle charge mode after charging in order to maintain the battery status and extend the battery life. Trickle charging refers to maintaining the charging state of the battery at a very low current to avoid overcharging and overdischarging, in order to protect the battery and extend the battery life. Trickle charging mode is usually suitable for lithium batteries, cadmium-nickel batteries, lead-acid batteries and other types of batteries.
In plain English, trickle charging means that when the mobile phone is fully charged, it will continue to charge, and then the charger will begin to charge the mobile phone with a small current, knowing that the mobile phone battery power reaches true saturation, that is, the most full state of charge.
