The maximum current that a battery can deliver is directly dependent on the internal equivalent series resistance (ESR) of the battery. The current flowing out of the battery must pass through the ESR, which will reduce the battery terminal voltage by an amount equal to the ESR multiplied times the load current (V = I X R). X R).
The Amp-hour capacity of a battery (or cell) is its most important figure of merit: it is defined as the amount of current that a battery can deliver for 1 hour before the battery voltage reaches the end-of-life point. The "c" rate is a current that is numerically equal to the A-hr rating of the cell.
2. Historical development of rechargeable batteries Batteries are by far the most effective and frequently used technology to store electrical energy ranging from small size watch battery (primary battery) to megawatts grid scale enenrgy storage units (secondry or rechargeable battery).
Which means (assuming ideal converter) that each battery has the capacity of 4.2 Wh. At 8.4 initial volts (and likely 7.6 running volts) it makes the battery capacity as about 550 mAh, which is likely it's real capacity. So, I would say that the discharge rate of about 55 mA is the right one for this battery.
high capacity, normal current (up to 2A discharge, usually 1A) - they exist up to 3400mAh currently. medium capacity, high current (the 10A ones) - they usually are around 2150mAh capacity values low capacity, very high current (25+A) - they are the power tools batteries, usually 1300-1600mAh capacity (2000 in certain cases)
The unit "mAh" is not amperage but is, instead, electric charge (the product of electric current and time). Further, the product of the battery's voltage and the electric charge rating is the amount of energy the fully charged battery can (ideally) supply.
