Question
What do you mean by boost voltage in case of battery 
charger?
 Question Submitted By :: Electrical-Engineering
I also faced this Question!!     Answer Posted By  
 
Answer
# 1
incase of battery charger you have two mode of charging .
1.float charge/trickle charge
2. boost charge.
incase of boost charge charging voltage will be high i.e 27
to 29 volts and charging current will increased and battery
can be charged fast.
this voltage is called boost voltage,

Answer
# 2
Battery charger having two mode of charging
1)Float charging ( constant voltage charging )
2)Boost charging ( constant current charging )
When battery goes for small discharg up to 10% it could
charged by float charging but if the battery goes to deep
discharge up to 50%it needs boost charging. In boost
charging keep the cell voltage of lead acid battery 2.65 &
charging current set 10% of AH capaicity of battery bank
Due to upper voltage level of batery charger battery takes
current & this current is controlled by charger controller
or by varing potentiometer( ie current limit pot)
