What is the difference between 2amp 4amp 6amp battery chargers?

Do electric golf carts require 110 volt or 220 volt outlet?

Electric golf carts operate from a DC voltage supply which is supplied by batteries. These batteries have to be charged on a regular basis. The voltage the battery charger operates on is governed by the manufacturer of the battery charger. Check the nameplate on the charger to see what voltage AC is required. Usually the chargers operate on 110 volts, but in some high capacity chargers they will operate on 220 volts. The nameplate will tell you what voltage is needed to operate the charger. That depends on the charger being used. Either is available.


Can you charge a 6 volt battery with 12 volt charger?

No. A 12 v battery will actually have a charged peak voltage of 13.54v or 13.58v. A six volt charger will have around a max 7.5v voltage. The 6v charger will think the battery has peaked and will discontinue charging.

Can you charge a 9.6 volt NiCad Battery Pack with a 6 volt charger?

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.
