With the improvement of living standard, electronic products such as mobile phones, notebooks computers, and digital cameras have been widely used in people's daily life. Lithium batteries play an important role in these high-tech consumer electronics.
Most electronic products currently available on the market are equipped with lithium batteries instead of Ni-MH ones. However, there are still some manufacturers who claim to use lithium batteries but actually use nickel cadmium and nickel hydrogen as usual. How to identify the fake lithium batteries?
Without special tools, you can try the following methods:
1. Weigh by hand: Of the same size, a lithium battery weighs lighter than a nickel hydrogen/cadmium one.
2. Use a lithium battery charger to charge the battery. If the battery temperature gets hot during the charging process, it is a Ni-MH battery or Ni-CD battery. If the temperature does not change greatly, it is a lithium battery.
3. Short-circuit the the negative electrode. If no electricity is produced, it is a lithium battery; otherwise, it is a Ni-MH or Ni-CD battery.
