The rechargeable battery on the market now turns out to be a wide range of brands are present. For digital cameras, the commonly used batteries can be divided into lithium-ion batteries, nickel metal hydride batteries, nickel-chromium batteries, alkaline batteries, the most popular of which is also the most mature battery technology also comes as nickel-metal hydride batteries.
Finally, I hope in the use of digital cameras and other digital devices can be more time efficient, safe to play the battery potential. Rechargeable battery is a miniature batteries can be said. The basic principle is the same with the car battery, from a metal material composition of positive and negative electrodes, in which adding a chemical energy storage media. Rechargeable battery in the factory is active in the production line, punching power and discharge. Laptop battery ACER Laptop Battery
Rechargeable batteries and alkaline batteries different from ordinary one. Ordinary battery with the discharge voltage decreases linearly, and can not be restored. The rechargeable battery while in use (loaded) when the voltage drop with the reduction in power, but to stop using (off load), the remaining amount of power regardless of how much the voltage will return to 1.2V or slightly below. Charging, the charging voltage higher than the battery voltage, charge, charge the battery voltage up to 1.4V or so general, but shelved for a while, the battery will charge back to 1.2V.
Any batteries, including batteries and rechargeable batteries, can not over-discharge. If light were reduced battery life, weight will be back into the battery short-circuit the battery completely damaged. The representation is the battery voltage drops below 1V, may have only a few tenths of V, a charge immediately washed over soon, but no one immediately connected electrical load.
It should be clarified, and very important. If you do not charge the battery long-term, should be let go of power, rather than washed over. Fully charged rechargeable batteries, such as long-term need, the role of the chemical within the battery will shorten the battery life, or even damage the rechargeable battery. This is not the same with the battery. The new rechargeable battery in the factory have been fully discharged. Rechargeable battery has no electricity can not see voltage. Rechargeable battery with or without electricity, voltage is 1.2V. By the following methods to verify: the new rechargeable battery (it did not red power) into DC, you will find not a few took no electricity.
In addition, the new rechargeable battery subject to 3 - 5 times the full charge and discharge, be at their best. Use rechargeable batteries should develop good habits, compulsory completely discharged (DC auto power off), then charging. Whether or not automatic charger, red immediately after the electricity and remove the rechargeable battery.
