for a rechargable 9 volt, about 4 hours for full battery.
It takes about 6 hours to charge a 7.4 volt battery when using a 5 volt charge. For the best results try charging it over night.
Depends entirely on how much current you use to charge it.
A .6 amp charger is a trickle charger. It would take days to charge a dead 12 volt battery with this charger. You need a 10 amp charger which will charge it in a couple of hours.
You cannot charge 108.5 volts with a 12 volt charger. What are you charging that has that kind of voltage?
How long does it take for an 18v battery to charge
It depends on the brand of the battery and or the charger used to charge it. But an average time of 5 hours is about right.
Yes it will, in the 12-volt position. But with the information given in the question, we can't estimate how long it will take.
Around 4 hours on a dead battery.
About 2 hours if the battery is 100% discharged.
