2. Zinc–carbon battery - Wikipedia

   en.wikipedia.org/wiki/Zinc–carbon_battery

   The zinc-chloride cell, frequently referred to as a heavy-duty, extra-heavy-duty, super-heavy-duty, or super-extra-heavy-duty battery, is an improvement on the original zinc–carbon cell, using purer chemicals and giving a longer service life and steadier voltage output as it is used and offering about twice the service life of general-purpose ...

4. 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 ...

5. List of battery sizes - Wikipedia

   en.wikipedia.org/wiki/List_of_battery_sizes

   The series comprised multi-cell carbon-zinc batteries used for portable electronic devices. Most sizes are uncommon today; however, the PP3 size (and to a lesser extent PP8, used in electric fencing, and PP9) is readily available. [ 251 ]

6. Battery leakage - Wikipedia

   en.wikipedia.org/wiki/Battery_leakage

   A leaking AA alkaline battery. Alkaline batteries use manganese dioxide and zinc electrodes with an electrolyte of potassium hydroxide.The alkaline battery gets its name from the replacement of the acidic ammonium chloride of zinc–carbon batteries with potassium hydroxide, which is an alkaline.

7. Alkaline battery - Wikipedia

   en.wikipedia.org/wiki/Alkaline_battery

   Alkaline batteries are manufactured in standard cylindrical forms interchangeable with zinc–carbon batteries, and in button forms. Several individual cells may be interconnected to form a true "battery", such as the 9-volt PP3-size battery. A cylindrical cell is contained in a drawn stainless steel can, which is the cathode connection.
