What's the best battery for Digital Camera Batteries? What's the best battery for Digital Camera ? The Digital Camera market uses mostly Li-ion batteries. In the last few years, environmental agencies have been attempting to discourage the use of Li-ion , especially in Europe. Li-ionhave been tried and tested in Digital camera for a number of years but the results are mixed. Shorter cycle life compared to NiCd is the major drawback.
The reasons for the relatively short life ofLi-ion are multi-fold. Li-ion is less robust than NiCd and has a cycle life expectancy that is half or one third that of the standard NiCd. In addition, NiMH prefers a moderate discharge current of 0.5C or less. A digital Camera , on the other hand, draws a discharge current of about 1.5A when transmitting at 4W of power. High discharge loads shorten the life of the Li-ion battery considerably. Li-on has the advantage of maintaining a low and steady internal resistance throughout most of its service life. Although low when new, Li-on increases the resistance with advanced cycle count. A battery with high internal resistance causes the voltage to drop when a load is applied. Even though energy may still be present, the battery cannot deliver the high current flow required during transmit mode. This results in a drop in voltage, which triggers the 'low battery' condition and the radio cuts off. This happens mostly during transmission.
The Li-ion has been tested for use with Digital Camera but has not been able to provide the ultimate answer. Higher replacement costs, restrictions posed by the safety circuit and aging pose limitations on this battery system. more info:www.good-battery.co.uk
