Answer / sudheer

The difference between a float charger and a trickle
charger is that the 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 ). You can keep it 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'll eventually boil the electrolyte out of
the cells or damage the plates. Trickle chargers will work
to keep the battery charged if used once a month or so for
a day or 2, but the float chargers can be left connected
indefinitely without potential harm to the battery.
For example, a 24 volt battery pack, comprising 12 2-volt
flooded lead-acid cells, which has been deeply discharged,
would normally be restored by a boost charge of
approximately 2.4 volts per cell for a short time (perhaps
around 72 hours). Once the collective cell voltage reaches
a surface charge of 28.8 volts (2.4 volts x 12 cells), the
charge rate would be switched to the sustained lower float-
charging rate of typically 2.23 volts.
Eventually, with the Boost charge removed, the surface
charge will diminish slightly and the battery-bank voltage
will stabilise at a preset float voltage, in the case of
the example above to approximately 27 volts (2.23 volts x
12).

Answer / anil vasu

Float voltage is the voltage applying to the cells to prevent self discharge. boost voltage is the voltage applying to the cells for charging after a discharge.
