Watts are the product of amps times volts. The amperage in a circuit is governed by the resistance of the load. A battery just supplies the potential as voltage, the load determines how much current is going to be drawn out of the battery. Batteries are rated in amp/hours. This means how long can a battery maintain a specific amperage over a period of time.
Remember that watts are voltage x current(amps) The number of watts you can get from a 48V battery will depend on how many amps the battery can deliver and how much the load can draw.
Absolutely not. I think it is possible, but it depends on how many Amps [or Watts] the refrigerator draws [uses], AND the sustained output [Amps or Watts] that the converter is capable of producing. For example, if the converter was rated for a sustained/continuous output of 10 Amps at 120 Volts [that's 1200 Watts], and the refrigerator requires only 6 Amps at 120 Volts [that's 720 Watts], then I say the converter can safely operate the refrigerator.Answer 3 -- Watt?Are you thinking of running a 120 volt refrigerator from a car battery? Back up to "absolutely not". There are RV refrigerators that can run for a short time from a car battery (preferably a deep-cycle type), but they can barely keep the fridge cool under the best of circumstances.Unless the engine is running, the battery will be drained in a couple of hours. If the battery is a deep-cycle, you can recharge it; if not, you'll have to buy a new battery.Also, if the fridge requires 720 watts and the converter is only 50% efficient, it's sucking 1500 watts from the battery, which is a lot more than leaving the headlights on. Even the little "six pack" coolers that run on 12 volts will run a battery down pretty quickly unless the engine is running. Try using an ice chest.
Not sure about how many Watts your 36 volt charger uses, but you can find out by this formula... Volts X Amps = Watts.
Volts * Amps = Watts 12 Volt * 2 amp = 24 Watts

It is called a deep cycle battery
As long as the battery is functional you can continue to jump it. However, know that every time you run a car battery down you shorten its life. A battery that is designed to be run completely down and then recharged is called a deep cycle battery. Automobile batteries are not deep cycle batteries. Discharging them completely causes damage to the battery itself.
Automotive batteries are not known for their "deep cycle" capabilities. If possible, don't allow them to EVER discharge completely.

About 400 watts when cycled on

You get actually energy (Watts) out of a battery, not calories (which is food energy).
There is no such thing as a "Normal" deep cycle battery. There are many common capacities, None are rated in Kilowatt/hour as they usually have less than 1. Most are rated in amp/hours "24DC model" batteries are between 94 amp/hours and 50 amp/hours at a nominal 12 rated volts.
There are several battery car systems that can be considered popular because many people used them. These are the flooded cell batteries, sealed batteries, deep cycle batteries and lithium-ion batteries.
