   The remaining capacity can also be withdrawn by reducing the current. For example, when the battery in the previous example reaches the cut-off voltage at 200 A, tapering the current down as necessary to keep the voltage at the low voltage cut-off value will enable nearly all the missing capacity to be taken from the battery (albeit over a ...

3. AA battery - Wikipedia

   en.wikipedia.org/wiki/AA_battery

   A Li-ion 1.5V AA-size battery, sold by the Chinese company Kentli as "Kentli PH5" since 2014 and with similar batteries later available from other suppliers is a AA-sized battery housing containing a rechargeable 3.7 V Li-ion cell with an internal buck converter at the positive terminal to reduce the output voltage to 1.5 V. [19] The Kentli ...

   A Battery: Eveready 742: 1.5 V: Metal tabs H: 101.6 L: 63.5 W: 63.5 Used to provide power to the filament of a vacuum tube. B Battery: Eveready 762-S: 45 V: Threa­ded posts H: 146 L: 104.8 W: 63.5 Used to supply plate voltage in vintage vacuum tube equipment. Origin of the term B+ for plate voltage power supplies.

5. Ampere-hour - Wikipedia

   en.wikipedia.org/wiki/Ampere-hour

   An AA size dry cell has a capacity of about 2,000 to 3,000 milliampere-hours. An average smartphone battery usually has between 2,500 and 4,000 milliampere-hours of electric capacity. Automotive car batteries vary in capacity but a large automobile propelled by an internal combustion engine would have about a 50-ampere-hour battery capacity.

6. Alkaline battery - Wikipedia

   en.wikipedia.org/wiki/Alkaline_battery

   An AA-sized alkaline battery might have an effective capacity of 3000 mAh at low drain, but at a load of 1 ampere, which is common for digital cameras, the capacity could be as little as 700 mAh. [12] The voltage of the battery declines steadily during use, so the total usable capacity depends on the cutoff voltage of the application.

7. Rechargeable alkaline battery - Wikipedia

   en.wikipedia.org/wiki/Rechargeable_alkaline_battery

   [8] [9] The capacity of a recharged alkaline battery declines with number of recharges, until it becomes unusable after typically about ten cycles. Low-ripple direct current is not suitable for charging disposable alkaline batteries; more suitable is a current pulsed at a rate of 40 to 200 pulses per second, with an 80% duty cycle.

8. Primary battery - Wikipedia

   en.wikipedia.org/wiki/Primary_battery

   A variety of standard sizes of primary cells. From left: 4.5V multicell battery, D, C, AA, AAA, AAAA, A23, 9V multicell battery, (top) LR44, (bottom) CR2032 A primary battery or primary cell is a battery (a galvanic cell) that is designed to be used once and discarded, and it is not rechargeable unlike a secondary cell (rechargeable battery).

9. Cutoff voltage - Wikipedia

   en.wikipedia.org/wiki/Cutoff_voltage

   The cut-off voltage is different from one battery to the other and it is highly dependent on the type of battery and the kind of service in which the battery is used. When testing the capacity of a NiMH or NiCd battery a cut-off voltage of 1.0 V per cell is normally used, whereas 0.9 V is normally used as the cut-off voltage of an alkaline cell ...
