The conversion of 650 mah to volts results in approximately 3.25 volts.
To convert milliamp-hours (mah) to volts, you need to understand the relationship between capacity (mah), voltage, and battery chemistry. Since mah measures charge capacity and volts measure electrical potential, a direct conversion requires knowing the battery’s voltage rating. For example, a typical lithium-ion battery with 650 mah capacity and a voltage of 3.7V will have 650 mah at 3.7 volts, so the voltage remains constant for that battery, but if you want a pure conversion of capacity to voltage without context, it’s not straightforward because they measure different things.
What is the conversion of 650 mah to volts?
Converting 650 mah to volts depends on the battery’s voltage rating. If you have a battery rated at 3.7V and 650 mah capacity, the voltage is that rated voltage, which is 3.7V. The capacity (mah) does not change the voltage but indicates how long the battery can supply power at that voltage. Therefore, 650 mah at 3.7V equals a battery with a charge capacity of 650 mah and a voltage of 3.7 volts.

Conversion Formula
Since mah measures capacity and volts measure potential difference, their conversion is based on battery chemistry. For a battery with known capacity and voltage, the voltage remains constant regardless of mah. For example, a lithium-ion battery rated 650 mah at 3.7V has a fixed voltage of 3.7 volts. The formula involves knowing the battery’s voltage and using it as a constant value. If you want to find volts from capacity, you need additional info about the battery’s chemistry and design, because capacity alone doesn’t determine voltage. To illustrate, if a battery’s capacity increases, it doesn’t change the voltage, but it allows longer use at that voltage.
Conversion Example
- Suppose you have a 1000 mah battery at 3.7V:
- Capacity: 1000 mah
- Voltage: 3.7V
- To convert 1000 mah to volts, since voltage is fixed, it stays 3.7V. Capacity tells us how long it lasts.
- Another example: 500 mah battery at 3.7V:
- Capacity: 500 mah
- Voltage: 3.7V
- Again, the voltage remains 3.7V, but the capacity is less, meaning shorter usage time.
- Finally, 1500 mah at 3.7V:
- Capacity: 1500 mah
- Voltage: 3.7V

Conversion Definitions
mah
Mah (milliampere-hour) measures the charge capacity of a battery, indicating how much current it can supply over time. It reflects the total stored energy, with higher mah meaning longer usage before needing recharge, but it doesn’t specify voltage or power directly.
volts
Volts (V) measure the electrical potential difference between two points. It determines the force that drives electric current through a circuit. In batteries, volts depend on chemistry and design, remaining constant for a given cell type, regardless of capacity.
Conversion FAQs
How does battery chemistry influence the voltage when converting mah to volts?
Battery chemistry defines the nominal voltage of a cell, affecting the voltage reading regardless of capacity. For example, lithium-ion batteries typically have 3.6-3.7V, while nickel-metal hydride cells are around 1.2V. Capacity (mah) doesn’t change with chemistry, only voltage does.
Can I determine the volts of a battery just by knowing its mah rating?
No, mah alone does not give information about volts. Mah indicates capacity, whereas volts depend on the battery’s chemical makeup. To find volts, you need to know the battery type or its voltage rating, which is usually specified on the battery label.
Why does increasing mah not necessarily increase a battery’s voltage?
Mah relates to charge capacity, while voltage is a measure of potential difference. Increasing mah means longer operation time at the same voltage, but it doesn’t alter the voltage itself. Voltage is determined by the materials and construction of the battery, not its capacity.
