The controversy first emerged in late-2016, when it was reported that since a recent iOS update, some iPhone handsets had begun to experience unexpected shutdowns when their battery capacity reached 30%, caused by drops in the battery's terminal voltage below a threshold of around three volts required for operation of the device.
Capacity loss or capacity fading is a phenomenon observed in rechargeable battery usage where the amount of charge a battery can deliver at the rated voltage decreases with use. [ 1 ] [ 2 ] In 2003 it was reported the typical range of capacity loss in lithium-ion batteries after 500 charging and discharging cycles varied from 12.4% to 24.1% ...
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] Primary batteries are not designed for recharging between manufacturing and use, and thus to be practical they must have much lower self-discharge rates than older types of secondary cells.

A battery management system (BMS) is any electronic system that manages a rechargeable battery (cell or battery pack) by facilitating the safe usage and a long life of the battery in practical scenarios while monitoring and estimating its various states (such as state of health and state of charge), [1] calculating secondary data, reporting that data, controlling its environment ...
The fine-grain structure also provided better anti-corrosion properties and enhanced battery performance in a 4 mol/L NaOH solution. At a current density of 10 mA/cm², the fine-grain anode showed a 41.5% increase in capacity density and a 55.5% increase in energy density compared to the coarse-grain anode.

The Remington Versa Max, also styled as VERSA MAX, is a gas-operated semi-automatic shotgun introduced by Remington Arms in 2010. It is chambered to use 12 gauge shells of 2 + 3 ⁄ 4 inches (7.0 cm), 3 inches (7.6 cm), and 3 + 1 ⁄ 2 inches (8.9 cm) in length. [4] It was named the shotgun of the year for 2011 by American Rifleman. [5]
