We have assembled this illustrative guide to help you safely pack and ship many kinds of batteries. In some cases, such as with alkaline or certain nonspillable lead-acid batteries, your responsibilities may be limited to simple steps such as: selecting strong outer packaging; carefully protecting battery terminals to prevent sparking or short circuit; and carefully preparing the interior
A standard AA battery typically has an average of 2000 to 3000 mAh or 2 to 3 Ah. These AA batteries have a voltage of 1.2V to 1.5V (equivalent to 2 to 4 Wh per cell) depending on the specific battery. As a result of multiple cells being connected in series, as with the use of a battery holder or pre-made battery packs, voltage increases, but
Batteries can explode through misuse or malfunction. By attempting to overcharge a rechargeable battery or charging it at an excessive rate, gases can build up in the battery and potentially cause a rupture. A short circuit can also lead to an explosion. A battery placed in a fire can also lead to an explosion as steam builds up inside the battery.

Zinc–carbon batteries of various sizes. A zinc–carbon battery (or carbon zinc battery in U.S. English) is a dry cell primary battery that provides direct electric current from the electrochemical reaction between zinc (Zn) and manganese dioxide (MnO 2) in the presence of an ammonium chloride (NH 4 Cl) electrolyte.

Technically, this is not an acid, but a strong base. However, it can still cause chemical burns. Lead batteries, such as car batteries, have sulfuric acid. Sulfuric acid can cause damage to the eyes and burn skin on contact. Another type of battery used in, for example, mobile phones, are rechargeable lithium-ion batteries. 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.
