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 ...
Some versions have a tap at 22.5 volts. GB Battery: C Battery Eveready 761: 1.5 to 9 V: Threaded posts or banana sockets H: 76.2 L: 101.6 W: 31.75 Originally used in vintage vacuum tube equipment for grid bias. Still popular for school science class use as a variable voltage supply as the current version has several taps at 1.5 volt intervals ...
The sum of all areas (multiplied by the current of 100mA) is the total energy extractable from the cell by constant-current discharge. Note: as the voltage and current are measured externally, the energy calculated in this way is explicitly work done in the load, that is, electrical work that the battery can do.
A zinc-carbon lantern battery, consisting of 4 round "size 25" cells in series. Terminated with spring terminals. 4LR25-2: 4: L: R: 25: 2: An alkaline lantern battery, consisting of 2 parallel strings of 4 round "size 25" cells in series 6F22: 6: F: 22: A zinc-carbon rectangular battery, consisting of 6 flat "size 22" cells. Equivalent to a PP3 ...
The amount of electrical current an alkaline battery can deliver is roughly proportional to its physical size. This is a result of decreasing internal resistance as the internal surface area of the cell increases. A rule of thumb is that an AA alkaline battery can deliver 700 mA without any significant heating. Larger cells, such as C and D ...

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).
A battery bank used for an uninterruptible power supply in a data center A rechargeable lithium polymer mobile phone battery A common consumer battery charger for rechargeable AA and AAA batteries. A rechargeable battery, storage battery, or secondary cell (formally a type of energy accumulator), is a type of electrical battery which can be ...
