How much does battery go down overnight?
Usually, my iPhone battery drains 15% to 20% overnight; but when this percentage borders to 30%, you need to think about the problem. Before you go for a battery replacement program, you can check some tips and tricks to fix iPhone idle battery drain issues.
What should car battery voltage be After sitting overnight?
That’s called a surface charge, and it drops back to the “rested” fully charged voltage after an hour or two, or after a small load has been applied for a short time. I hope this helps. Thanks for the question.
What should battery voltage drop after 6 months?
If you have had the battery continually undercharged for 6 months, it may have lost a lot of capacity. If you measure the voltage immediately after the end of a drive, it should be more like 13.2, and drop to 12.7 within a few minutes as the chemical reactions in the battery slow down and stop when you stop charging it.
Is it normal for a battery to lose charge?
During none-use hours it is normal for a battery to lose some charge due to normal parasitic discharge caused by computer modules. The electricity is used to keep computer memory alive. Since a battery is at its peak storage ability when it is new it will lose storage ability as it ages.
What’s the lowest voltage I should accept on a brand new car battery?
Batteries do lose charge over time. Frequently, a car battery will be around 13.5V or higher, but if the charge drops to 90% (normal shelf storage percentage), the voltage will drop to ~12.6 to 12.8. ( Source)

Why does my ATV battery keep losing charge?
To test if your battery holds a charge, simply disconnect both terminals and fully charge the battery. Use a multimeter to measure the voltage. If it still loses its charge over a day or two, you likely have a bad battery. Notice that this behavior may be due to internal sulfation, which sometimes can be fixed.
