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.
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.
I've added the battery size (AA), and changed the 33 ohm to 330 mW. Without the full context the 33 ohm made no sense (the battery was powering a boost converter, and the 33 ohm load was connected to the output of the converter, not to the battery). At 1.5V, a 33 ohm load would only draw 68mW. Prevalence 19:59, 12 May 2019 (UTC)

Typical Duracell 9V battery. Duracell Inc. is an American manufacturer of alkaline batteries, specialty cells, and rechargeables; it is a wholly owned subsidiary of Berkshire Hathaway since 2016. The company has its origins in the 1920s, through the work of Samuel Ruben and Philip Mallory, and the formation of the P. R. Mallory Company.
Most manufacturers claim that overcharging is safe at very low currents, below 0.1 C (C/10) (where C is the current equivalent to the capacity of the battery divided by one hour). [23] The Panasonic NiMH charging manual warns that overcharging for long enough can damage a battery and suggests limiting the total charging time to 10–20 hours. [22]
An electric battery is a source of electric power consisting of one or more electrochemical cells with external connections [1] for powering electrical devices. When a battery is supplying power, its positive terminal is the cathode and its negative terminal is the anode. [2] The terminal marked negative is the source of electrons.
An "inside-out" form with a carbon cup and zinc vanes on the interior, while more leak-resistant, has not been manufactured since the 1960s. [7] 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 ...
