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.
Corrosion of the external metal parts of the lead–acid battery results from a chemical reaction of the battery terminals, plugs, and connectors. Corrosion on the positive terminal is caused by electrolysis, due to a mismatch of metal alloys used in the manufacture of the battery terminal and cable connector. White corrosion is usually lead or ...
Service life of several thousand hours (continuous operation) [9] Shelf stable over several years (retaining 90% of initial capacity) [10] Silver oxide cells are a primary battery and do not have a cycle life or a rate of charging and discharging. [2] Typical silver oxide cells are stable at temperatures below 100°C, at which point leakage can ...
Severe PCB corrosion from a leaky PCB mounted Ni-Cd battery. Printed circuit boards (PCBs) are vulnerable to environmental influences; for example, the traces are corrosion-prone and may be improperly etched leaving partial shorts, while the vias may be insufficiently plated through or filled with solder. The traces may crack under mechanical ...
A typical 12 V, 40 Ah lead-acid car battery. An automotive battery, or car battery, is a rechargeable battery that is used to start a motor vehicle.. Its main purpose is to provide an electric current to the electric-powered starting motor, which in turn starts the chemically-powered internal combustion engine that actually propels the vehicle.

General Motors, and other automobile manufacturers, have also begun using side-post battery terminals, which consist of two recessed female 3/8" threads (SAE 3/8-16) into which bolts or various battery terminal adapters are to be attached. These side posts are of the same size and do not prevent incorrect polarity connections.
Vessels, pipelines and tanks (including ballast tanks) which are used to store or transport liquids can also be protected from corrosion on their internal surfaces by the use of cathodic protection. [ 39 ] [ 40 ] ICCP and galvanic systems can be used. [ 41 ]
