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 ...
Maximum discharge current: 1 mA. Maximum pulse discharge current: 5 mA. CR1612: 16 × 1.2 Rare, used in Casio Film series watches. CR1616: 50–55: 0.1: 16 × 1.6 Used in automobile key remotes and in Game Boy cartridges (for powering the RAM for saved games). CR1620: 5009LC: 75–78: 0.1: 16 × 2.0 Used in automobile key remotes and early ...
Because the current is constant, the area under the graph is proportional to the energy extracted from the battery (i.e. the work done in the load). An area of 1 hour * 0.1V is equivalent to an energy of 3600s * 0.1V * 100mA = 10mWh or 36J. Marked on the graph are two voltages: 1.1 and 1.3V.
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.
The first generation rechargeable alkaline batteries were introduced by Union Carbide and Mallory in the early 1970s. [3] [5] Several patents were introduced after Union Carbide's product discontinuation and eventually, in 1986, Battery Technologies Inc of Canada was founded to commercially develop a 2nd generation product based on those patents, under the trademark "RAM".

By 1934, the system had been revised and extended to 17 sizes ranging from NS at 7 ⁄ 16 inch diameter by 3 ⁄ 4 inch height, through size J at 1 + 3 ⁄ 4 inches diameter by 5 + 7 ⁄ 8 inches high, to the largest standard cell which retained its old designation of No. 6 and which was 2 + 1 ⁄ 2 inches in diameter and 6 inches high.
