It was submerged in the ground for 10 hours from 7:00 am to 5:00 pm, but when tested again, it was found that not a single point of the specified voltage was exhausted.
It is a practical experiment.
Depletion of power due to the weak wet ground does not touch the two positive (+ -) positive and negative battery poles.
1. Light
2. sound
3. Heat
4. Magnet
5. Reluctant movement
6. Leakage of lead in the battery
Only one of the above six points will drain the battery. Otherwise, it is guaranteed that the battery will never run out, even if it is left on the ground.
I left it on overnight without removing the plug, but I could not get it out again. I dropped the battery on the ground.
I was informed that I could not run out of energy even though I left it.
