9 Volt Batteries Contain 6 AAAA Batteries

The batteries in most consumer electronics produce 1.5 volts each.

Different products use different numbers of batteries to achieve different voltage requirements. For example, a TV remote might be designed to run on 3 volts, so two 1.5 volt batteries will provide the necessary voltage when connected in series.

Larger devices, such as radios with large speakers or large kid’s toys, typically have larger batteries, like C and D cells. Smaller devices often use AA and AAA batteries, allowing the devices themselves to be smaller. All of these batteries output 1.5 volts, but the larger batteries have much higher capacities, meaning they last longer. D batteries have four times the capacity as AA’s. So, if you’re going to be blasting music on the beach, you’ll change fewer batteries if your radio uses D batteries.

There are many other types of batteries that are not 1.5 volts. One of the most popular is the nine-volt battery, which is technically called a PP3 battery. Smoke detectors, garage door remotes, transistor radios and a variety of other devices use these batteries.

They’re pretty convenient, giving you the voltage of six batteries after only inserting one battery. In fact, that’s exactly what they are — they’re just containers that link six smaller batteries together. Here’s a picture of a nine-volt battery that I took apart:

Each of the six batteries outputs 1.5 volts, giving a total of 9 volts when connected in series. The name brand nine-volt batteries usually contain six quadrouple A batteries (AAAA) which are rather uncommon in consumer electronics but find a home in medical devices such as glucose meters.

Some of the lesser known battery brands may contain 6 flat cells which are not easily reusable. As you can see in the picture above, AAAA batteries are very close in size to AAA cells. That’s worth noting since they could save the day if you’re short on AAAs:

Keep in mind, device manufacturers often use standard batteries in their rechargeable products and you can replace them yourself.

    This is not true.

      If you have reliable sources that indicate anything contrary to what I have stated, I’d be happy to include the most accurate information possible.

    Very interesting. These are the kind of secrets I like to see.

    9V energizers consist of AAAA cells too – however thay are slighly shorter than regular AAAA – and a tiny bit thinner due to the missing label.

    I have a tablet stylus that takes a AAAA battery. I can’t see buying a package of multiples just for one. I don’t know how long each lasts or how to prevent depletion while the stylus is not in use.

    Forgot to ask the question. . . Can i use one from the 9V pack?

    Not any more.
    I took a dead 9V alkaline apart a week ago & it had 6 flat batteries stacked on top of each other.
    There wasn’t any dead space between each cell.

      different companies probably have different methods of manufacture for these.
