This is what happened to the dog that bit the power bank. sparks flewThey set the blanket on fire and the fire spread throughout the house. There were no people there at the time.

AA Batteries vs 18650 Batteries

In general, you should always keep batteries on hand. away from children and petswhatever type they are. But it is true that not all of them are equally dangerous.

The most common type of battery used in small electronic devices is AA batteries. These are small batteries, about Diameter 15 millimeters and length 50 millimeters.and can be disposable or rechargeable. Their small size gives them many uses, but also some drawbacks that are eliminated by the 18650. Diameter 18 mm and length 65 mm.; but, in addition, they have a much higher charge density.

There are 18650 batteries. Large capacity and longer service life than the AA type. But its biggest advantage, at least when it comes to the Oklahoma dog incident, is its safety. To prevent short circuits, the positive and negative electrodes of the battery are separated. In addition, a protective plate can be installed to prevent overload, further increasing the service life.

With AA batteries, any break can cause the positive and negative electrodes to touch, causing sparks and potential fire. It is for this reason, among other advantages, that 18650 batteries are the most commonly used in Electric vehicles.
