Biting a Battery: Old Wives' Tale or Scientific Fact?

Battery life is a pressing concern for many consumers. However, an age-old suggestion for extending battery life is to bite it. This practice has various proponents and detractors, leading to a mix of folklore and seemingly scientific explanations. Let's delve into the truth behind biting batteries for longevity.

Why Biting a Battery Might Actually Work

Some enthusiasts swear by the practice of biting or denting batteries, particularly AA or AAA types. They argue that dented batteries can enhance their performance for several days, especially in low-drain devices like remote controls. This belief stems from personal experiences such as:

Biting batteries to test if they still work. Restoring dead batteries by denting them. Improving remote control function by denting the batteries.

These practices can sometimes rejuvenate battery performance by shifting internal chemicals and potentially exposing previously unreachable cathode or anode material. However, these claims are often anecdotal and lack scientific validation.

Proponents’ Arguments

Proponents of biting batteries cite various reasons for their effectiveness:

Increased Contact and Power Output: Dented batteries might provide better contact with the device's contacts, leading to improved power output. Chemical Redistribution: The process of biting might redistribute internal chemicals, providing a temporary boost in performance. Soft Batteries: In the past, some batteries had softer cases, making them more prone to denting. These soft cases could allow for greater contact with electrodes, thus enhancing battery performance.

Scientific and Safety Perspective

However, the scientific and safety community strongly advises against biting batteries. Here’s why:

Risks of Chemical Exposure: Biting a battery can cause physical damage leading to leakage of harmful chemicals. This can pose a significant health risk. Short Circuiting: The act of biting or denting can create a short circuit, leading to overheating, fire, or even explosion. This is particularly concerning with batteries designed to be sealed and non-rechargeable. Warranty Voiding: Performing such actions voids the manufacturer's warranty, leading to potential financial and liability risks.

The Case of the Samsung Note 7

A stark example of the dangers of bites and dents in batteries comes from the infamous Samsung Note 7. The batteries in these devices contained issues that led to internal shorts and subsequent explosions. This led to the recall of millions of units, underscoring the risks associated with damage to battery integrity.

Conclusion

In conclusion, while biting a battery might restore some functionality in low-drain devices, it poses significant risks and is not recommended. Proper usage, such as maintaining appropriate temperature and cleaning contacts, is the best way to extend battery life. If you experience issues with device batteries, consider using replacement batteries or consulting an expert for proper handling and care.
