Hello:
——★1. This is the phenomenon of Nikon digital camera lithium battery over-discharge: the lithium battery needs to be charged in time when it is exhausted.
——★2. Don't worry: once the battery voltage is over-discharged, the voltage will drop quickly, and you need to charge it in time at that time. If you have difficulty charging, you can charge it directly with a suitable charger (put the camera away), and then use the camera to charge it after the voltage is increased.
Principle: The camera is designed with a power management module, which will enter a protection program when it detects that the battery voltage is too low. Just throw away the protector and start charging.
Why can't Canon camera batteries be charged?
If the battery is not used for a long timeiodine, it will discharge automatically. Even if it is very low, the voltage will drop. significantly over time. I think your battery is too low. If possible, you can use a seat charger or universal charger to directly charge the battery. If it can still be charged, it won't be a big problem once fully charged, it can be used normally! If this doesn't work, the battery is useless, replace it with a new one!
Today's rechargeable batteries are generally lithium batteries. If the battery cannot be charged, there are no more than three reasons: Battery damage, battery leakage, wire disconnection, etc.
After a long period of non-use, the battery plates are passivated and need to be “activated”.
When the battery is stored for a long time, due to low power, it is inferiorure to the protection voltage after self-discharge and the circuit is locked.
You can do this by activating it, and it will slowly recover after charging and unloading it several times. If the circuit blockage is not serious, it can be recovered by trickle charging and discharging.
If the battery is damaged, you should go to a battery repair shop to confirm whether it can be repaired and find out the repair cost.
