Thanks for your contribution and thoughts but you CAN use a 4.2 volt charger for a 3 volt battery.JyotNo. You should not use a 4.2V charger for a 3V battery. The charger is specifically designed for the battery. Attempting to use a non rated configuration, unless the charger states clearly on its label that it can handle the 4.2V battery, could result in overcharge, overheat, even fire.Even attempting to place a resistor or zener diode in series with the battery is not a good idea, because some chargers use the voltage/time curve to sense when the battery is fully charged, and this will bias the results.
No, if they are wired in series you have 36 volts assuming each battery is a 12 volt battery. They will have to be wired in parallel to output 12 volts. In that case you can charge them with a 12 volt charger but it will take 3 times as long as charging just one 12 volt battery.
The answer depends upon the construction of the 6 volt battery. If you can treat it as two 3 volt batteries then the answer is YES otherwise NO. Charge each section separately inserting a low wattage torch bulb between the charger and battery cell to limit the current. Choose the bulb to prevent execissive charging rate; an ammeter would come in handy. The main risk is EXPOSION if you charge too fast! Put the battery to be charged inside a strong box for safety. If in doubt buy a new battery charger, they are cheap.
You cannot do this. If it were a 36 volt charger you could connect three 12 volt batteries in series and charge all 3 at the same time. But this is a 32 volt charger which I have never heard of.
Impossible to do with a single 6 volt battery.
You can but the motor may not run, however you will not burn the motor.
Any 12 volt battery charger with an automatic feature. I own a Schumacher 520A-PE and it is an excellent inexpensive charger for the homeowner. It will charge at 10 amp to recharge an auto battery in about 3-5 hours. Also has a 2 amp trickle charge to maintain a stored battery as on a lawn mower. Will shut off when done to prevent overcharging.
There are many different brands for that kind of charger such as Duracell, CTEK 56-353,Yuasa Batteries, Ryobi 12v, and True Gel Cell Battery Tender Plus 12VBattery Charger Deltran Battery Tender JuniorBattery Tender Plus 12 volt 1.25 mp 3 Stage Smart ChargerPower Tender Plus 12 volt 5 amp WaterproofBattery Tender 10-Bank 12V Battery Management SystemBattery Tender 12vPulse Tech Xtreme 2 bank chargerGuest 12V 6 Amp ChargerBatteryMinder 12 volt Charger/Maintainer/Conditioner.

Yes, you can make a 36 volt charger into a 24 volt charger, but it is not as simple as reducing the voltage with a resistor or a regulator.Chargers are designed for the specific requirements of the battery. This includes not only voltage, but current and (sometimes) the slope of the voltage over time. (NiCads are a very specific example of the latter.) Additionaly, you need to consider the power dissipation of the device that drops the voltage from 36V to 24V - As an example, if the charger is putting out 5A, you are talking about a dissipation, just for the step down of 12V, of 60W, and that might be a significant amount of heat that would have to be dissipated safely without setting anything on fire.Better to buy a charger specifically designed for the battery.
They use a 1/3N 3 volt battery. AimPoint models which do not use AA batteries also use the same battery.
