Chemistry
In an alkaline battery, the anode (negative terminal) is made of zinc powder (allows more surface area for increased rate of reaction therefore increased electron flow) and the cathode (positive terminal) is composed of manganese dioxide. When describing standard "AAA battery", "AA battery", "C", "sub-C" and "D" type cells, the anode is the flat end while the cathode is the end with the raised button.

Alkaline batteries are comparable to zinc-carbon batteries, but the difference is that alkaline batteries use potassium hydroxide (KOH) as an electrolyte rather than ammonium chloride or zinc chloride, have the ability to deliver more current (although not necessarily more amp-hours), and have a longer shelf-life than zinc-carbon and zinc chloride batteries. The chemical compound potassium hydroxide, (KOH) sometimes known as caustic potash, potassa, potash lye, and potassium hydrate, is a metallic base. ...
An electrolyte is any substance containing free ions that behaves as an electrically conductive medium. ...
Ammonium chloride (NH4Cl) (also Sal Ammoniac, salmiac, nushadir salt, zalmiak, sal armagnac, sal armoniac, salmiakki, salmiak and salt armoniack) is, in its pure form, a clear white water-soluble crystalline salt of ammonia with a biting, slightly sour taste. ...
Zinc chloride (ZnCl2) is a colorless or white compound of zinc and chlorine that is extremely hygroscopic. ...
The half-reactions are:[1]
- Zn (s) + 2OH− (aq) → ZnO (s) + H2O (l) + 2e−
- 2MnO2 (s) + H2O (l) + 2e− →Mn2O3 (s) + 2OH− (aq)
Capacity Unlike NiMH rechargeable batteries, alkaline batteries are normally not sold with a nominal capacity. Alkalines have a high internal resistance, and a high thermal coefficient of resistivity — the faster an alkaline battery is drained, the higher percentage of the load it dissipates as heat. Therefore, the capacity of an alkaline battery is strongly dependent on the load, even at moderate loads. An AA-sized alkaline battery might have an effective capacity of 3000 mAh at low power, but at a load of 1000 mA, which is common for digital cameras, the capacity could be as little as 700 mAh.[2] A nickel metal hydride battery, abbreviated NiMH, is a type of rechargeable battery similar to a nickel-cadmium (NiCd) battery but has a hydrogen-absorbing alloy for the anode instead of cadmium. ...
Capacitance is a measure of the amount of electric charge stored (or separated) for a given electric potential. ...
The output impedance, source impedance, or internal impedance of an electronic device is the opposition exhibited by its output terminals to the flow of an alternating current (AC) of a particular frequency as a result of resistance, induction and capacitance. ...
Electrical resistivity (also known as specific electrical resistance) is a measure of how strongly a material opposes the flow of electric current. ...

Current The amount of 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 general rule of thumb is that an AA alkaline battery can deliver 1000mA without any significant heating. Larger cells, such as C and D cells, can deliver more current. Applications requiring high currents of several amps, such as high powered flashlights and boom-boxes, will require D sized cells to handle the increased load. Volume for volume, alkaline batteries have inferior current handling capacity when compared to other chemistries like NiCd and NiMH. However, alkaline batteries cost significantly less.
Recharging of alkaline batteries -
Main article: Recharging alkaline batteries Some alkaline batteries are designed to be recharged, but most are not. Attempts to recharge may cause rupture, or leak hazardous liquids which will corrode the equipment. 2 Duracell-Brand AAA Alkaline batteries Recharging Alkaline Batteries is a way of renewing expended alkaline batteries. ...
Leaks Over time, alkaline batteries are prone to leaking potassium hydroxide, a caustic agent that can cause respiratory, eye and skin irritation. This can be avoided by not attempting to recharge alkaline cells, not mixing different battery types in the same device, replacing all of the batteries at the same time, storing in a dry place, and removing batteries from devices for storage. The chemical compound potassium hydroxide, (KOH) sometimes known as caustic potash, potassa, potash lye, and potassium hydrate, is a metallic base. ...
Disposal Unlike other types of batteries, Alkaline batteries can be disposed of as regular domestic waste in some locations. [3][4] The state of California, however, has made it illegal to throw alkaline batteries as regular domestic waste.[5] In Europe the battery disposal is controlled by the WEEE regulations, and as such alkaline batteries must not be thrown in with domestic waste. They should be disposed through local recycling stations / waste dumps. In the EU also most stores which sell batteries (i.e. supermarkets) can be used to dispose old batteries because they are required by law to recycle old batteries. WEEE is the European Community directive on Waste Electrical and Electronic Equipment which together with the RoHS-Directive became European Law in February 2003, setting collection, recycling and recovery targets for all types of electrical goods. ...
