This is at the voltage of the battery, typically 3.7V. What does 2500 mAh mean? The energy E (Wh) in watt-hours is equal to the electric charge Q (mAh) in milliamp-hours times the voltage V (V) in volts (V) Battery life = Battery capacity in mAh / Load current in mAh So, if your phone has a capacity of 2,500 mAh and has a load of 500 mAh, then your calculation will look like this: 5 hours = 2,500/500 mAh Meaning, if you charge your phone to full capacity, then it mAH is the amount of milliamperes which a battery can provide (to a circuit or device) for the amount of hours [math]\text{Voltage of a battery can not be known from its ampere hour capacity.}[/math] This is done at the batterys voltage, which is usually 3.7V. But it depends on Description. Its a battery rating for the devices battery. For example, with a 1300mAh battery, you could continuously draw 1300mA. Youve provided insufficient data. mAh only has meaning if the voltage is specified in advance. Without a specific voltage, an (Amps for a set Time 2500 mAh means that the battery can produce 2500 milliamp hours of power. 1-48 of over 1,000 results for "2500mah battery" RESULTS Price and other details may vary based on product size and color. The mah means milli-amperes hour. Nominal Capacity: 2500mAh. Maximum Voltage: 4.2V. Amazon.com: Tenergy Premium Rechargeable AA Batteries High Capacity 2500mAh NiMH AA Battery AA Cell Battery 12 Pack : Health & Household EBL AA Rechargeable Batteries 1.2V 2500mAh High Performance Pre Consequently, the larger the capacity in mAh the higher the amount of energy. The capacity of batteries is indicated as XXXX mAh (milliampere/hour). Last updated on Oct 03, 2022 19:29:06 PDT View all revisions. Wh to mAh calculator milliamp-hours to watt-hours calculation. If the smartphone uses 100 mA for an hour from the battery of 2500 mAh , then that battery can deliver energy upto 25 hours solidly. What does Mah mean when youre in a battery? Milliampere-hours to ampere-hours formula. The formula for calculation is as follows: Capacity $17.95. Volt is a unit of energy per unit of charge, defined as[math] 1\frac{Joule}{Coulomb}=1Volt[/math]. Ampre-hour is a unit of capacity, defined as [m Li-Ion, 2500mAh, BT110 Battery,The BT110 battery is designed for Business radios.
