Chargers: Some are pure battery killer

NiMH batteries take - depending on the model - different amounts of energy and therefore need different charging currents as well as a corresponding loading control. Cheapest chargers that are often available for less than 10 euros, including Dell Vostro 1510 battery, ignore the battery-specific characteristics and load each inserted cell continuously with a constant charge current. In addition, they usually lack a charging time control with shutdown and reverse polarity protection, so that an incorrectly inserted Dell Y9943 battery inevitably breaks down. Since the charger does not know when the Dell xps m1330 battery is fully charged, it does not reduce the charge current to the end of the loading phase. The result is that the cell is heated by strong and wears out sooner. These battery chargers are the most pure Dell Inspiron 1520 battery killer and shorten the life of your batteries significantly. In the best case, you charge the Dell Inspiron 6400 battery in such a bad charger only - to the detriment of the operating time while shooting. Inexplicably, some chargers that come with digital cameras are one of those battery destroyers.
