The Yongnuo Speedlite YN686EX-RT is compatible with Canon’s RT- series of flashes‚ but contrary to Canon’s units uses a lithium-ion battery said to be faster and offer 750 full-power flashes from a single charge. When lithium batteries became a common thing in the market‚ some photographers managed to fry their flashes‚ because they picked a set of AA lithium batteries and used them

ABSTRACT The Batteries form a significant part of many electronic devices. Typical electrochemical batteries or cells convert chemical energy into electrical energy. Batteries based on the charging ability are classified into primary and secondary cells. Secondary cells are widely used because of their rechargeable nature. Presently‚ battery takes up a huge amount of space and contributes to a large part of the device’s weight. There is strong recent interest in ultrathin‚ flexible‚ safe energy storage

Introduction Batteries are used every day in a variety of different devices. They allow us to charge an object and store power for later use. While batteries are a big part of daily human life they also present a challenge to society in terms of environmental sustainability. Not only do these batteries have harmful chemicals which can end up in landfills‚ but they also encourage over consumption because the more products you buy‚ the more batteries you need‚ and the more batteries must be produced

Cell Lead acid cells were invented in 1859 by the French Physicist Gaston Plante‚ and are the oldest types of rechargeable batteries. These types of batteries typically weigh at 5kg‚ but can range from half a kilogram to over 30 kilograms on the consumer market. Though their chemistry means a very low energy-to-weight and energy-to-volume ratio in comparison to other modern batteries‚ their ability to supply high surge currents means that the cells maintain a large power-to-weight ratio. This makes
