This solution has gained popularity due to the significant price difference between car batteries and generators powered by gasoline, diesel, or gas.
However, despite their availability and affordability, using car batteries for these purposes comes with a number of dangers and limitations.
Using a car battery in an apartment poses a serious threat to health and safety. First, charging the battery releases hydrogen gas, which can accumulate in enclosed spaces and create an explosion risk, especially in the presence of a spark.
Nevertheless, if all safety precautions are observed, car batteries can be used to power certain household devices. These devices include laptops, mobile phones, power banks, televisions, and various lamps.
For this, an inverter is required—a voltage converter that connects to the battery, with devices plugged into the inverter.
However, there are limitations. It is not recommended to connect devices that require stable and high current to a car battery, such as gas boilers, refrigerators, microwave ovens, washing machines, and other sensitive appliances.
The inverter used to power such devices may not provide the necessary quality of current, leading to equipment damage. For example, a refrigerator connected to a battery may fail due to improper sine wave voltage, which can result in breakdown or even fire.
