Battery leakage is the escape of chemicals, such as electrolytes, within an electric battery due to generation of pathways to the outside environment caused by factory or design defects, excessive gas generation, or physical damage to the battery.
Self-discharge is a phenomenon in batteries. Self-discharge decreases the shelf life of batteries and causes them to have less than a full charge when actually put to use. [1] How fast self-discharge in a battery occurs is dependent on the type of battery, state of charge, charging current, ambient temperature and other factors. [2]
"In an alkaline battery, the anode (negative terminal) is made of zinc powder (which allows more surface area for increased rate of reaction therefore increased electron flow) and the cathode (positive terminal) is composed of manganese dioxide." I just opened a big stack of them, the zinc is the solid outer casing, cathode.

Just prior to World War II, a standard 90-degree battery-operated flashlight was adopted for the U.S. Army with the designation TL-122. [4] The TL-122 was itself a slightly altered version of the angle-head, brass-bodied Eveready Model No. 2694 Industrial flashlight and the No. 2697 Boy Scout flashlight, first introduced in 1927.
Lantern batteries are physically larger and consequently offer higher capacity than the more common flashlight batteries. Lantern batteries comprise multiple cells inside a housing. The most common variant in the US is the 6-volt square-base battery with spring terminals. In Europe the most common one is the 4.5-volt flat pack.
A truck driver ignored cops’ warnings Thursday that his tractor-trailer was too big to make it through the Brooklyn-Battery Tunnel — and yes, he got stuck, plugging traffic between Brooklyn ...
Progressive corrosion of zinc–carbon batteries This picture shows the zinc container of fresh batteries at (a), and discharged batteries at (b) and (c). The battery shown at (c) had a polyethylene protection film (mostly removed in the photo) to keep the zinc oxide inside the casing.
