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 ...
4.5 + 4.5: H: 91.3 L: 65.1 W: 52.4 This battery contained two independent 4.5 V batteries, and had a four-pin connector. 9 V with a center tap was available by wiring in series. There were two ⌀3.2 mm negative pins spaced 9.5 mm apart and two ⌀4.0 mm positive pins spaced 14.3 mm apart. Negative and positive pins were spaced 18.1 mm apart.

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.

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).
In April 2015 researchers at Stanford University claimed to have developed an aluminium-ion battery with a recharge time of about one minute (for an unspecified battery capacity). [7] Their cell provides about 2 volts, 4 volts if connected in a series of two cells. [7] [25] The prototype lasted over 7,500 charge-discharge cycles with no loss of ...
The remaining capacity can also be withdrawn by reducing the current.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 ...
