• In the RC circuit shown, the battery has fully charged the capacitor, so Q0 = C E. Then at t = 0 the switch is thrown from position a to b. The battery emf is 20.0 V, and the capacitance C = 1.02 μF. The current I is observed to decrease to 0.50 of its initial value in 40 μs. (a) What is the value of Q, the charge on the capacitor, at t = 0?
Battery life doesn''t depends on count cycle but it temperature dependant since high temperature may decrease the capacity concern and also keeping with low charge also affect the life since the battery would have some percentage of discharge rate would be better if you would Only charge when battery is down to 20%.

What you need to know about battery charge current
Basically, A battery voltage is maintained at 4.2V, the charging current gradually decreases, and the charging speed becomes slower. This stage is mainly to ensure that the battery is fully charged.The battery is fully charged when the charging current is lower than 0.1C or 0.05C.
The ABSORPTION stage (the remaining 20%, approximately) in the AGM/flooded 12 volt charger has the charger holding at the absorption voltage (between 14.4 VDC and 14.7 VDC, depending on charger set points) and decreasing the current until the battery is fully charged. If the battery won''t hold a charge, or the current does not drop after the ...

21.6: DC Circuits Containing Resistors and Capacitors
This voltage opposes the battery, growing from zero to the maximum emf when fully charged. The current thus decreases from its initial value of (I_9 = frac{emf}{R}) to zero as the voltage on the capacitor reaches the same value as the emf. When there is no current, there is no (IR) drop, and so the voltage on the capacitor …

Do''s and Don''ts: 6 Things to Keep in Mind When Charging Your Car Battery
How do I know when my car battery is fully charged? The car battery will last approximately 1.5 hours without being charged. This depends on many factors, including how cold it is outside and how much the car is driven. The best way to charge a car battery is to do it right before you are driving the car.
The battery is initially at zero volts, so no charge is on the capacitor. Slide the battery slider up and down to change the battery voltage, and observe the charges that accumulate on the plates. Display the capacitance, top-plate charge, and stored energy as you vary the battery voltage.
It''s normal for a laptop battery''s full charge capacity to decrease over time due to factors like charge cycles, temperature, and usage.
