The conversion of 650 mah to volts results in approximately 3.25 volts. This is because, assuming a typical lithium-ion battery, 1 mah roughly equals 0.005 volts when converted directly, considering the capacity and voltage relationship.

In more detailed terms, milliamp-hours (mah) measure battery capacity, while volts indicate the electrical potential. To estimate volts from mah, you need to know the battery’s voltage rating, usually around 3.7V for lithium-ion cells. Multiplying the capacity by the voltage per unit gives an approximate voltage, but since capacity and voltage are different characteristics, the conversion is only rough unless specific battery details are known.
Introduction
Converting mah to volts involves understanding the relationship between a battery’s capacity and its voltage. While they measure different things, knowing how to estimate volts from mah can be useful in selecting or comparing batteries.

Conversion Formula
The formula to convert mah to volts is based on multiplying the capacity in mah by the voltage per unit of capacity. For example, most lithium-ion batteries have a voltage of about 3.7V. Therefore, the calculation is: volts = mah * 0.005. This works because 1 mah roughly equals 0.005 volts in many small batteries, but this is an approximation.
Step-by-step math for 650 mah: 650 mah * 0.005 = 3.25 volts. This shows that a 650 mah battery with a voltage of 3.7V would output around 3.25 volts when fully charged, although actual voltage can slightly vary depending on battery chemistry and condition.
Conversion Example
- Convert 700 mah: 700 * 0.005 = 3.5 volts.
– Take 700 mah.
– Multiply by 0.005 (volts per mah).
– Result: 3.5 volts. - Convert 600 mah: 600 * 0.005 = 3.0 volts.
– Take 600 mah.
– Multiply by 0.005.
– Result: 3.0 volts. - Convert 750 mah: 750 * 0.005 = 3.75 volts.
– Take 750 mah.
– Multiply by 0.005.
– Result: 3.75 volts. - Convert 800 mah: 800 * 0.005 = 4.0 volts.
– Take 800 mah.
– Multiply by 0.005.
– Result: 4.0 volts. - Convert 625 mah: 625 * 0.005 = 3.125 volts.
– Take 625 mah.
– Multiply by 0.005.
– Result: 3.125 volts.

Conversion Definitions
mah
Mah (milliamp-hours) measures the capacity of a battery, indicating how much current it can supply over a specific time. Higher mah means a longer-lasting battery for devices but does not directly indicate voltage or power output.
volts
Volts measure the electrical potential difference or pressure in a circuit, indicating how much energy each unit of charge carries. Voltage determines the power a device receives and is independent of battery capacity.
Conversion FAQs
How reliable is converting mah to volts using the 0.005 factor?
The 0.005 factor is a rough approximation based on typical lithium-ion batteries with an average voltage of 3.7V. Actual voltage can vary depending on battery chemistry, age, and charge level, so this conversion provides an estimate, not an exact value.
Can I use this conversion for all types of batteries?
No, this conversion is primarily applicable to lithium-ion batteries with a voltage around 3.7V. Other battery chemistries like NiMH or lead-acid have different voltages and capacities, making this calculation inaccurate for them.
Why does my battery’s voltage not match the conversion result?
Because actual battery voltage varies during discharge, and the mah rating reflects capacity rather than voltage. The conversion gives an estimated voltage based on typical values; real-world measurements can differ due to battery condition and load.
Is it possible to convert mah directly to watt-hours?
Yes, by multiplying mah by volts and then dividing by 1000. For example, a 650 mah battery at 3.7V has watt-hours of (650 * 3.7)/1000 = 2.405 Wh. This conversion accounts for both capacity and voltage, giving energy content.
