I need to use an angle grinder to cut locks at a self storage facility (Don't worry, it's legal. I own the facility.). I have looked into cordless grinders but they are expensive, don't provide a whole lot of power and don't last very long.
I want to be able to put a car battery on wheels and plug the 7 amp angle grinder into it.
My first question: Is this possible?
Second question: How do I connect an outlet (or a power inverter) to the car battery?
Third question: How long will a car battery last doing this?
Fourth question: Can I recharge the battery in between uses?
Thanks for your help! Feel free to refer me to another website with the answer.

You would need to connect the battery to an inverter to convert the DC power to AC. I can't give you specifics on how to do this, but it is possible. I would recommend going to your local hardware or auto parts store to see if they have anything. You might also be able to find something from Granger or another industrial supplier.

You do it with an inverter and you get the power you need by buying a big enough inverter. It connects normally to a vehicle battery and is recharged from the vehicle generator and is commonly used in smaller RV's. The outlet is on the front of the box and you just plug in. Sure you can recharge the battery between uses. Car batteries (except deep discharge like for trolling) do NOT like to be completely discharged - damages their capacity. In an RV, there is a box with terminals to go to the alternator and to the vehicle and accessory batteries. It allows recharging the accessory, but does not drain the vehicle battery along with the accessory. With the cost of inverters of this capacity, you may find you would be better off with a 12 volt air compressor and a cheap air drive die grinder with a cut off wheel or a battery powered reciprocating saw with a tungston carbide blade. the latest hot tool for thieves faced with padlocks, succeeding the old standby of small oxy-acetyline tanks and cutting torch.

Yes you will have to buy an inverter that converts 12VDC to 120 AC.
7 Amps at 120 volts is going to equal to approximately 840 watts: So you are going to need at least a 900 to 1,000 watt inverter.
If you can't find on at your local auto parts dealers you can find them at most TSA truck stops. or travel stores at most big Truck stops. You can also fight them at truck dealers. I mean by that dealers that sell 18 wheelers like Peter Built, Kenworth. Internationals.
The biggest I have seen in truck stops was a 5,000 watt unit. That thing could almost power a whole house.
1,000 watt units are fairly common in trucks now days because most drivers have refridgetors in their trucks, entertainment centers and computers in their trucks, and instead of running their engines all night they use electric blankets when it is real cold.
Plus a lot of them have small electric stoves so they can cook and not have to pay the high prices at truck stop restaurants.
You will also need a battery charger to charge up your battery between uses Not cheap rinky dink one, a good one. It might cost you more money up front but cheaper in the long run.
Another place I just thought of you can look is at your local R.V. dealers (Travel trailers) They use a lot of 12 volt self contained appliances like air conditioners, ice boxes, They also do it the other way and have inverters to convert 12VDC to 120 VAC..

If you are trying to remove padlocks, why not just buy large bolt cutters? You could avoid all the electrical.
I have an inverter on my truck battery to run 110V equipment but the problem is the drain on the battery. It will not last very long before requiring a recharge.

Sure we use a car outlet (power plug) in our car to use you computer all the time. Just get a converter from your car's cigarette lighter socket to a regular household outlet (about $35).
Plug it into your car and plug your extension cord into the outlet and use it like any other outlet in your house or garage. I suggest keeping your vehicle running so the motor will charge the battery while you are working.
