How Many Amps In A 9v Battery

How Many Amps In A 9v Battery – I worked alternately as a theater technician, doing a mix of carpentry and electrical work to build sets and lighting systems.

Once, for a production of West Side Story, our crew hired an old arc welder from Hobart to build parts of the set out of a chain-link fence (subtlety wasn’t in the production budget). We were fascinated to discover that the welder is literally an extremely powerful welder, using high-intensity direct current to simultaneously melt the steel and forcefully eject the molten debris.

I was interested to see if the same effect could be achieved on a much smaller scale with a lower powered DC source. Fortunately, I discovered that another theater I worked at was throwing away a number of half-used 9V batteries from their wireless microphones. These batteries tend to be changed very often, because no theater wants to risk Maria’s microphone cutting out halfway through “I Feel Pretty.”

Since many of the used batteries still had a lot of power left, I started storing them. A useful feature of the 9V batteries are the metal “clips” that allow easy connection to each other, which allowed me to connect all my batteries in series to create a ~100V DC power bank .

Batteries are rated in ampere-hours, which is a unit related to energy content. The idea is that if I have a 10 amp hour battery, I can draw one amp for ten hours, or 10 amps for one hour, or 2 amps for 5 hours, etc. The only limit to the amount of current that can be drawn is the internal resistance of the battery, which will constantly heat up as the current increases.

In the video below, it is obvious what happens when my 81V circuit C with a ridiculous current is discharged through a graphite rod (pencil lead) into a thin piece of steel wire. As the steel wire heats up, it gradually begins to melt, resulting in the orange glow you see at the end of the video. The strange top hat I’m holding was the closest thing I could find to a UV filter at the time, as it’s not advisable to look directly into the arc. Please excuse some of the poor directing decisions involved in making the video, but definitely watch the last ten seconds:

My guess is that the break at the end is the result of the inside of the graphite heating up relative to the outside, resulting in differential thermal expansion across the wire and eventual mechanical failure (this is also why the windshield it breaks if you pour boiling). water it in winter). Fortunately, I was wearing glasses and gloves at the time.

In the end I had to stop my experiments, because the now overheated batteries started to hiss at me. But what I love about this project is that it directly shows the connection between the low-power electrical devices we encounter every day and the dramatic electric arcs we find in science classrooms. A nine-volt battery, or 9-volt battery, is an electric battery that offers a nominal voltage of 9 volts. Actual voltage is 7.2 to 9.6 volts, depending on battery chemistry. Batteries of different sizes and capacities are produced; a very common size is known as PP3, introduced for early transistor radios. The PP3 has a rectangular prism with rounded edges and two polarized plugs on top. This type is commonly used for many applications, including household ones such as smoke and gas detectors, clocks and toys.

The nine-volt PP3 battery is commonly available in primary zinc-carbon and alkaline chemistries, in primary lithium iron disulfide and lithium manganese dioxide (sometimes designated CRV9).

), and in the form of charge in nickel-cadmium (Ni-Cd), nickel-metal hydride (Ni-MH) and lithium ions. Live batteries of this format, once common, are banned in many countries due to their toxicity.

Designations for this format include NEDA 1604 and IEC 6F22 (for zinc-carbon) or MN1604 6LR61 (for alkaline). The size, regardless of chemistry, is commonly referred to as PP3, a designation originally reserved exclusively for carbon-zinc, or in some countries, E or E-block.

In the past, a range of PP batteries was produced with voltages of 4.5, 6 and 9 volts and different capacities; the larger 9 volt PP6, PP7 and PP9 are still available. Other 9 volt battery sizes are available: A10 and A29.

These cells are slightly smaller than LR8D425 AAAA cells and can be used in their place for some devices, although they are 3.5mm shorter. The carbon-zinc types are manufactured with six flat cells in a stack, enclosed in a moisture-proof housing to prevent desiccation. Primary types of lithium are made with three cells in series.

9-volt batteries accounted for 4% of primary alkaline battery sales in the United States in 2007, and 2% of primary battery sales and 2% of secondary (rechargeable) battery sales in Switzerland in 2008 .

Historically, the now popular PP3 battery size was a member of the Power Supply (PP) battery family that was originally manufactured by Ever Ready in the UK and Eveready in the US. The company says it introduced the PP3 battery in 1956.

Only sizes PP3, PP6, PP7 and PP9 are produced, with PP3 being extremely common. Modern batteries have larger capacities and lower internal resistances than early versions.

Before the mid-1950s, in the days when vacuum tube (valve) radios used batteries designed specifically for vacuum tubes, there was a nine-volt mains polarized battery, or “C” battery (USA), which had taps for different voltages. 1.5 to 9 volts.

Early transistorized radios and other equipment needed a miniature battery of suitable voltage. Early transistor radios required a 22+ 1⁄2 volt battery. Although the transistors would theoretically operate from lower voltages, the point contact transistors used in 1954 had to operate very close to their V.

Limit to obtain the required frequency response. However, a miniature battery suitable for hearing aids (vacuum tube) was already being sold.

The PP3 (physically identical to the 6LR61 or 1604A) appeared when portable transistor radios became common and were labeled as a transistor battery or transistor-radio battery.

The PP3 battery has both plugs in the socket to hold a d. The smaller round (male) terminal is the positive and the larger hexagonal or octagonal (female) terminal is the negative contact. The battery connectors are the same as the charging device; the smaller connects to the larger and vice versa.

The same clip style connector is used on other types of batteries in the Power Pack (PP) series. Battery polarity is usually obvious, as mechanical connection is only possible in one configuration.

A problem with this type of connector is that two loose batteries with open terminals can touch and short, discharge, and cause heat and possibly fire.

Three different types of internal 9-volt primary batteries: rectangular zinc-carbon cell (6F22), rectangular alkaline cell (6LP3146), and cylindrical alkaline cell (6LR61).

Most often, a “9-volt” battery refers to a transistor radio size called PP3 or IEC 6F22 or NEDA 1604, although there are less common nine-volt batteries of different sizes.

Batteries of all types are produced in consumer and industrial grades. More expensive industrial-grade batteries may use chemistries that provide a higher power-to-size ratio, have less self-discharge and therefore a longer life when not in use, greater resistance to leakage, and e.g. , the ability to cope with high temperatures. and the humidity associated with medical autoclave sterilization.

Battery Chargers & Rechargeable Batteries

Most battery testers and chargers that can also test nine volts need another bracket to hold the battery, while cylindrical batteries often share a bracket that can be adjusted for size.

Because of the close proximity of the positive and negative terminals on the top of the battery and the relatively low speed of most common batteries, an informal method of voltage testing is to place the two terminals across the tongue. A strong tingling would indicate a battery with a heavy charge, an abscess, a dead battery. Although stories of unfortunate results circulate, the process is rarely dangerous under normal circumstances, although it can be uncomfortable.

9 volt lithium batteries are high energy disposable batteries. In the PP3 size, they are typically rated between 0.8 and 1.2 Ah (eg >1.2 Ah @ 900 ohms at 5.4 V @ 23 °C for one type),

Approximately twice the capacity of alkaline batteries. Some manufacturers claim that the energy can be five times that of alkaline. When it comes to powering small electronic devices and gadgets, batteries play a vital role. And a popular type of battery used is the 9V battery. But have you ever wondered how many amps are in a 9V battery? Understanding your battery’s current capacity is critical because it determines how much power it can deliver to your devices.
