I've disassembled some Radio Shack brand 9V batteries in the 1970s and found that they contained a stack of six almost-rectangular cells, rather than the usual six long skinny ones. 9V is louder than 3V. (The design that allows cheap wall clocks to run off a single AA battery is quite neat, and I'd like to see a good reverse engineering of it.). More than one doctor bill has been attributed to something along the lines of kids who wanted to snack ona battery. A great alternative is to get yourself a rechargeable replacement or discover another type that operates on C or D cells instead. PX625 397 Take a look at any battery, and you'll notice that it has two terminals. 384 And the maximum power available is at a load current that drops half the battery voltage across that internal resistance. The 9V battery is an extremely common battery that was first used in transistor radios. Smoke alarms and multimeters are a couple of examples - redesigning would cost money and wouldn't substantially reduce the BOM cost or increase marketable functionality. Common applications for 9V batteries include smoke detectors, carbon monoxide detectors, wireless microphones, and LED flashlights. Bulk Key Fob Batteries And that's why you don't see them in many flashlights, for example. This is partially due to the chemistry types being open to interpretation (especially for lithium cells) and partially due to the possibility of different geometric constructions (e.g. So yes, there are many different form factors represented in your junk drawer. However, a suitable miniature battery was already marketed for (vacuum tube) hearing aids. 321 Keep them out of reach of children or pets. If you have a security system that uses 9V, disposable ones will help keep you safer for longer.
