The batteries can be arranged in different ways to get the voltage you’ll need for your power inverter. If you are using a 1000 watt at12 volt power inverter, you will need 2 units of 6 volts batteries connected in series to come up with the 12 volts.
The most dangerous part of this process is the liquid in the battery. The liquid is sulfuric acid that will seriously burn you. As a safety precocious, always have some baking soda nearby to neutralize the acid in case you spilled some on your body.
Another safety tip says that the gasses that come off from the battery, hydrogen gas (H2), can be hazardous as well. It is highly flammable. Make sure you work with the batteries in an open space and no sparks or open flame nearby.
