So, for example, a typical AA Ni-MH rechargable battery has a nominal cell voltage of 1.2V. If you find one with a capacity of 2,000mAh, it would have a 2.4Wh rating. If you want to take a Wh rating and convert it to mAh, divide it by the voltage of the battery ; and multiply that by 1000. For example: A 90Wh battery that has a voltage of 12V.
Let''s look at an example using the equation above — if a battery has a capacity of 3 amp-hours and an average voltage of 3.7 volts, the total energy stored in that battery is 11.1 watt-hours — 3 amp-hours (capacity)
1. Understanding Battery Capacity Definition and Measurement. Battery capacity is the amount of electrical energy a battery can store and is typically measured in milliampere-hours (mAh) or watt-hours (Wh).Milliampere-hours denote the charge capacity, while watt-hours represent the energy capacity. A higher capacity means the battery can store more energy,

With it, you should be able to calculate the maximum charging or discharging power given the storage capacity, i.e. maximum power in MW = storage capacity in MWHr x C-rating.

The relationship between voltage and power capacity of lithium batteries is a complicated one. The answer depends on the material used to make the battery. The electrodes have varying thickness, which affects their discharge rates. Smaller particles of active materials are used to improve rate performance. Higher concentration of lithium salt in the electrolyte
The relationship between voltage, amperage, and power is defined by the equation: Power (Watts) = Voltage (Volts) × Current (Amperes). For example, at 12 volts, a battery providing 50 amps results in 600 watts of power. Battery capacity is indirectly related to both voltage and amperage. It refers to how much energy a battery can store and

Battery Capacity vs. Discharge Rate. The capacity of a battery refers to the amount of energy it can store, and the discharge rate refers to how quickly that stored energy is released. Understanding the relationship between battery capacity and discharge rate is essential for optimizing charging and discharging processes.
battery can be discharged for pulses of up to 30 seconds. This limit is usually defined by the battery manufacturer in order to prevent excessive discharge rates that would damage the battery or reduce its capacity. Along with the peak power of the electric motor, this defines the acceleration performance (0-60 mph time) of the vehicle.
The higher the capacity, the longer a battery can power a device. For example, a battery with a 100Ah capacity can theoretically supply 100 amps for one hour or 10 amps for ten hours. However, real-world performance may vary depending on the application, environmental conditions, and depth of discharge (DoD). The Relationship Between
In conclusion, the relationship between voltage and amps in a battery has a significant impact on its performance. The choice between higher voltage and higher amps involves a trade-off between power output, battery capacity, and device size. Careful consideration of these factors is necessary to select the best battery for a given application.
The higher the power, the quicker the rate at which a battery can do work—this relationship shows how voltage and current are both important for working out what a battery is suitable for. Capacity = the power of the battery as a function

Power Tools: Power tools, such as drills and saws, commonly use lithium-ion battery systems rated between 4 to 20 amps. These batteries provide the high power necessary for short bursts of high-demand usage. For example, a cordless drill may use a battery rated at 12 amps, designed for extended use without losing charge.
There are high-capacity cells, with higher energy density, and cells with less nameplate capacity. One important thing for power tools is an ability to supply high peak
As such, the overall power density (given the same volume of the cell) is smaller. That's why mass-produced power tools use cells of seemingly lower capacity, say 1500 mAh. Now, to increase total battery capacity they use a bunch of same cells (or series string of cells) in PARALLEL.
One important thing for power tools is an ability to supply high peak currents to overcome start-up inrush currents for motors, and to handle load. So the battery cells must be of "high-discharge" type. High discharge means smaller internal resistance (ESR) and therefore require thicker foil electrodes and current collectors.

One important thing for power tools is an ability to supply high peak currents to overcome start-up inrush currents for motors, and to handle load. So the battery cells must be of "high-discharge" type.
Load: The connected load affects battery performance, with higher loads often resulting in lower voltages and decreased capacity. Age and Usage Patterns: Over time, batteries naturally degrade, and frequent deep discharge cycles can further reduce capacity.
Thus the battery becomes more "powerful" automatically (can deliver more current). So there is no artificial "current limiter" inside power tool battery pack (besides the fire protection), the limitation comes from property of individual primary cells used to make the battery. I see. That makes sense.
You are very quick to judge. "Typical measure for the power-to-energy ratio is C or P-rate... C-rate refers to battery's rate in constant current charge/discharge rate vs. its capacity whereas P-rate, a term commonly used by battery manufacturers, is the battery's rate in constant power charge/discharge rate vs. its capacity.
