当你开启数码相机,打开LCD构图时,当你在一个美丽的风景区使用数码相机留影时……突然,数码相机的LCD显示屏出现了一个红色的警告标志——电池没电;或者当你在使用数码相机过程中,突然从电池仓中冒出浓浓的焦味;更加让人痛心的是由于使用假冒电池而使让爱机终身“瘫痪”。由此可见,数码相机电池的选购相当重要。下面介绍数码相机电池的相关知识,供你选购和使用时参考。1.镍氢电池镍氢电池是早期镍镉电池的替代产品,相对于镍镉电池来说,镍氢电池具有以下优势:它极大减少了镍镉电池存在的“记忆效应”,使镍氢电池的使用更方便,循环使用寿命更长。此外,镍氢电池还具有容量高、放电深度大、耐过充和过度放电、充电时间短等优点。最重要的是镍氢电池不再
When you turn on the digital camera, open the LCD composition, when you use a digital camera to take a picture in a beautiful scenic area ... Suddenly, the digital camera’s LCD display shows a red warning sign - the battery is dead or when you In the process of using a digital camera, suddenly emerge from the battery compartment thick burning smell; even more sad is due to the use of fake batteries and let love machine lifelong “paralyzed.” This shows that the purchase of digital camera batteries is very important. The following describes the digital camera battery knowledge, for your purchase and use of reference. 1. NiMH batteries NiMH batteries are an early replacement for nickel-cadmium batteries, compared to nickel-cadmium batteries, nickel-metal hydride batteries have the following advantages: It greatly reduces the nickel-cadmium batteries exist “memory effect” so that NiMH The use of battery more convenient, longer cycle life. In addition, the nickel-metal hydride battery also has the advantages of high capacity, large depth of discharge, overcharged and overcharged, short charging time. The most important thing is nickel-metal hydride battery no longer
