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 ...
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.
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. [1]

An LED flashlight has a longer battery life than an incandescent flashlight with comparable output. [10] LEDs are also less fragile than glass lamps. LED lamps have different spectra of light compared to incandescent sources, and are made in several ranges of color temperature and color rendering index. Since the LED has a long life compared to ...
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.
The 2nd generation iPad Pro and The 3rd generation iPad Air models can develop a glowing white spot on the display which is located above the home button. This is a problem caused by the display cable underneath pushing against the back of the display, creating a pressure point. [13] [14]
