A 1.5-ton air conditioner typically requires a power supply from an electrical outlet or a dedicated circuit, rather than batteries. Air conditioners of this size are designed to operate on standard alternating current (AC) power. The power requirement for a 1.5-ton air conditioner typically ranges from 1200 to 1500 watts, depending on the specific model and energy efficiency.
Using batteries to power an air conditioner of this capacity would be impractical due to the high power demands. The energy stored in batteries is usually measured in watt-hours (Wh) or ampere-hours (Ah), and the capacity of batteries available for domestic use is significantly lower compared to what is required to operate a 1.5-ton air conditioner for any meaningful duration.
It's important to ensure your air conditioner is connected to a suitable electrical supply with the correct voltage and amperage rating. If you have specific requirements or situations where a battery-powered solution is necessary, it's advisable to consult with an electrical engineer or a professional in the field to explore alternative options and solutions.
