Battery Pack Calculator | Good Calculators
Here''s a useful battery pack calculator for calculating the parameters of battery packs, including lithium-ion batteries. Use it to know the voltage, capacity, energy, and maximum discharge
by linking to Amazon.com and affiliated sites. A lithium-ion battery voltage chart shows the relationship between a battery's voltage and its state of charge (SOC), helping users understand how charged or depleted the battery is.
What this means is that the maximum voltage of the cell is 4.2v and that the "nominal" (average) voltage is 3.7V. As the battery is used, the voltage will drop lower and lower until the minimum which is around 3.0V. You should see the number 3.7V written on the battery itself somewhere.
The voltage of lithium batteries typically ranges from 3.2 to 3.7 volts per cell, depending on the chemistry. The capacity, measured in milliampere-hours (mAh) or ampere-hours (Ah), can vary significantly, usually ranging from 500 mAh to over 5000 mAh. The capacity impacts the battery's run time and suitability for different devices.
No. 3.7V is the nominal (average) voltage, not the fully charged state. A battery at 3.7V is about 50% charged. For full charge, the voltage should reach 4.2V. At what voltage is a lithium-ion battery considered dead? When a lithium-ion battery drops to around 3.0V or below, it is considered fully discharged or “dead.”
