Yes, energy will be lost to the battery. In electric batteries, electrochemical reactions which take place inside the battery, in addition to other factors such as material resistivity and temperature, will cause the battery to possess an internal resistance.
When switched off there is no significant drain on a battery regardless of its type. However they will over time lose some of their charge due to the nature of batteries, which are essentially contained chemical reactions that produce an electrical current. Even when not use, this process continues to go on, but at a much slower rate.
That's approximately 3.4kWh gone up in the air, which is 34% of the battery. And this is happening a couple of times a week. I ran a couple of tests, and it appears that 1kWh of battery charge is lost per day! Of course, we have raised this issue with GE (GivEnergy), and initially, they told us that recalibrating the battery would fix the problem.
If the protection circuit or the detection cabinet is out of control, the charging voltage will be greater than 5V, causing the electrolyte decomposition, violent reaction inside the battery, rapid rise of internal pressure of the battery. Eventually the battery explodes.
Root cause 2: Too long storage time. Lithium batteries are stored for too long, resulting in excessive capacity loss, internal passivation, and increased internal resistance. Solution: It can be solved by charging and discharging activation. Root cause 3: Abnormal heat.
Of course, we have raised this issue with GE (GivEnergy), and initially, they told us that recalibrating the battery would fix the problem. Recalibrating simply means discharging the battery to 0% and then charging it to 100% so the software can learn the bottom and top values.
