Can I just swap out a 9 volt battery with a DC power supply?
However, in general you can simply replace a 9V battery with a regulated 9V DC (!) supply. DC is important. The power supply should have an "equals"-sign printed on it after the 9V, where one of the two straight lines is dashed. If it is labeled "9V~", then it will put out AC (alternating voltage), which is surely not a replacement to a battery.

6 FAQs about [9V battery output power]
What is the voltage of a 9v battery?
Despite its name, the actual voltage of a 9V battery typically ranges from 7.2 to 9.6 volts, depending on its chemical composition and state of charge. While the nominal voltage of a 9V battery is 9 volts, it’s important to understand that this voltage isn’t constant throughout the battery’s life:
How many watts is a 9 volt battery?
A 9-volt battery has a nominal voltage of 9 volts and a typical capacity of around 500 mAh. This means that it can provide around 4.5 watts of power for an hour, or 0.45 watts for 10 hours. How Many Amps are in 9 Volts? There are 9 volts in a single amp. A 9-volt battery has about 400-600 milliamps of current.
How many amps can a 9 volt battery deliver?
When you think about a 9-volt battery, it’s key to know its amp capacity. A standard 9-volt battery commonly delivers about 0.5 to 1 amp-hour. This means you can use 0.5 to 1 amp for a whole hour. But the actual amps your battery can deliver depend on the battery type and age.
What is the maximum current output of a 9v battery?
The maximum current output of a standard 9V battery is relatively low compared to other battery types. It’s worth noting that drawing 500mA is considered an unreasonably high current for a 9V battery, and even 100mA is rather high for sustained use. The capacity of a 9V battery varies depending on its chemistry:
How long does a 9 volt battery last?
A standard 9-volt battery has a capacity of about 0.5 to 1 amp-hour. This means it can supply 0.5 to 1 amp of current for one hour. You can think of it like this: if you use a device that draws 1 amp, the battery will last for about an hour. However, if your device uses only 0.5 amps, the battery will last about two hours.
What is a 9V 1 amp battery?
A 9V 1 Amp Battery is a type of battery that is commonly used in electronic devices. It is a primary cell battery that contains cells with aqueous electrolytes and manganese dioxide as the cathode material. The anode is made of zinc, and the separator between the anode and cathode is usually paper or plastic.
