"A method of maintaining a rechargeable battery in a fully
charged condition by continuous, long-term, constant-
voltage charging, at a level sufficient to balance self-
discharge. also called trickle charging. " (source-
babylon dictionery.com)



Trickle charging, also called float charging, means
charging a battery at the same rate as it is self-
discharging, thus maintaining a full capacity battery. Most
rechargeable batteries, particularly nickel-cadmium
batteries or nickel metal hydride batteries, have a
moderate rate of self-discharge, meaning they gradually
lose their charge even if they are not used in a device.
One must be careful, however, that if a battery regulator
is not employed, the charge rate isn't greater than the
level of self-discharge, or overcharging and possible
damage or leakage may occur ( source wikipedia)

Answer / umair qayyum

float has circuitry to prevent overcharging. It senses when
the battery voltage is at the maximum level and temporarily
shuts off the charge (floats voltage at zero or a very
minimal charge until it senses that the battery output
voltage has fallen, then resumes charging ). It may be kept
connected indefinitely.
A trickle charger, on the other hand, will charge no matter
whether the battery is fully charged or not, so it needs to
be connected and disconnected periodically. If left in place
too long, it will eventually boil the electrolyte out of the
cells or damage the plates.
