Obviously the appearance is not enough and it is easy to counterfeit, but measuring the voltage with a multimeter, the capacity with a smart charger and testing the discharge rate can be very indicative.
Actually the article does not provide any info about that and it just misses what is promises in the title.
Asking chatgpt seems more useful than reading the article ;-)
- Too light: Counterfeit batteries often weigh less because they use smaller or inferior cells.
- Overheating or fast discharge: Fake batteries often fail to hold charge properly and heat up quickly.
- Use a charger to measure actual capacity. If it’s far below the claimed value, it’s fake.
- Use a multimeter to check actual voltage. If it’s far off from the expected range (e.g., below 3.0V or above 4.2V per cell), the battery might be damaged or fake.
