<div align=justify>What is the Secrets of <A href="http://www.good-battery.com/">Battery</A> Runtime? What is the runtime of a portable device directly related to the size of the <A href="http://www.good-battery.com/">battery</A> and the energy it can hold? In most cases, the answer is yes. But with <A href="http://www.good-battery.com/digital-camera-battery.html">digital </A>equipment, the length of time a <A href="http://www.good-battery.com/digital-camera-battery.html">battery</A> can operate is not necessarily linear to the amount of energy stored in the <A href="http://www.good-battery.com/digital-camera-battery.html">battery</A>. we examine why the specified runtime of a portable device cannot always be achieved, especially after the <A href="http://www.good-battery.com/">battery</A> has aged. We address the four renegades that are affecting the performance of the battery. They are: declining capacity, increasing internal resistance, elevated self-discharge, and premature voltage cut-off on <A href="http://www.good-battery.com/battery-charger.html">discharge</A>. The amount of <A href="http://www.good-battery.com/battery-charger.html">charge</A> a battery can hold gradually decreases due to usage, aging and, with some chemistries, lack of maintenance. Specified to deliver about 100 percent capacity when new, the <A href="http://www.good-battery.com/camcorder-battery.html">battery </A>eventually requires replacement when the capacity drops to the 70 or 60 percent level. The warranty threshold is typically 80 percent. The energy storage of a <A href="http://www.good-battery.com/pda-battery.html">battery </A>can be divided into three imaginary sections consisting of available energy, the empty zone that can be refilled and the rock content that has become unusable. Figure 6-1 illustrates these three sections of a <A href="http://www.good-battery.com/mobile-phone-battery.html">battery </A>. In nickel-based <A href="http://good-battery.com/power-tools-battery.html">batteries</A>, the rock content may be in the form of crystalline formation, also known as memory. Deep cycling can often restore the capacity to full service. Also known as ‘exercise’, a typical cycle consists of one or several discharges to 1V/cell with subsequent discharges. The loss of charge acceptance of the Li-ion/polymer batteries is due to cell oxidation, which occurs naturally during use and as part of aging. <A href="http://www.good-battery.com/digital-camera-battery.html">Li-ion batteries</A> cannot be restored with cycling or any other external means. The capacity loss is permanent because the metals used in the cells are designated to run for a specific time only and are being consumed during their service life.
