数码相机应该怎样充电？英文双语对照

　　不同的数码相机充电方式是不同的，有的是放在相机里充电的，有的是拿出来用专门的充电器充电。　　关于充电时间　　我们可以确定“头三次充电要充满12小时以上”这句话放在几年前那是完全正确的，因为镍氢（镉）电池拥有记忆效应，前三次要把它的“胃”撑到最大，让电池了解自己的最大饱和度，以达到长时间使用的效果。而现在普遍使用的锂离子电池，自身没有记忆效应，这样就完全没有必要再多充好几个小时，不仅浪费电量，而且对电池本身的寿命也有很大的影响。建议各位消费者首先根据充电器、充电电池和相机说明书来进行操作。有很大一部分消费者是懒得去看说明书特别是充电这一块的，而最终导致了错误的操作方法。　　电池身上的注意事项　　下面我们来详细讲解一下锂离子电池的正确充、放电方法：　　当锂电池搁置一段时间不用后，则进入休眠状态，此时使用时间逐渐变短。不过锂电池激活很简单，只需要进行3－6次正常的充放电循环就可激活电池，恢复正常容量。关于充电时间，我们建议各位遵循产品说明书上的指示来进行操作。锂电池在电池充满后都会自动停充，并不存在镍电充电器的持续多小时的“涓流”充电，长时间充电则使电池的充放电保护电路长期处在危险的边缘徘徊，对电池的寿命会造成很大的消减。　　尼康相机说明书充电说明　　充电如此，那放电呢？同样不能过度的进行放电操作。过度放电同样是镍电池流传下来的方法，当时是为了减少记忆效应，但这对锂离子电池却是有所损害的。曾经就有人因为过度放电导致锂离子电池电压过低，无法开机致使返回客服维修。因为锂电池的设计特殊性，它比镍电池更容易受到损伤。通常要长时间充电我们只好利用晚上的时间来进行操作，但一般情况下夜间的电压会比白天高一些，对娇贵的锂离子电池来说也是一个潜在的危险。　　佳能相机说明书充电说明　　作为结尾，我们再强调一下锂离子电池的正确使用方法：　　①电池若长时间不用，请充电70%左右存放于干燥、阴凉处。镍氢电池3月左右再足量充电一次；锂电池6月左右再充电一次；　　②按照说明书标准的时间和程序充电，即使是前三次也要如此进行，一般情况下卡片机锂电池在2－5小时之间即可充满；　　③当设备出现电量过低提示时，应该尽量及时开始充电，不要过度放电；　　④锂电池的激活并不需要特别的方法，在正常使用中锂电池会自然激活。　　最后希望各位在使用数码相机和其它数码设备的时候能够更加的高效、安全的来发挥电池的最大潜力。

Distinct digital watch for an opportunity charges means is different, have a plenty of those who be put in camera to charge, have a plenty of take charge with special charger. About charging we can decide time " the head charges 3 times should be full of 12 hours of above " before this word is put in a few years, that is completely correct, because of nickel hydrogen (cadmium) batteries has memory effect, before 3 secondary it " stomach " maintain the biggest, let batteries understand his the biggest degree of saturation, with achieving the result that uses for long. And the lithium ion cell that uses generally now, oneself does not have memory effect, not was necessary completely to charge several hours more again so, waste n not only, and also have very big effect to the life of batteries itself. Proposal everybody consumer above all according to charger, charge batteries and camera manual will undertake operating. Have very big one part consumer is to be disinclined to go to this one seeing a manual charge especially, and the operation method that caused an error finally. What we explain lithium ion batteries in detail below the note on batteries body is correct fill, discharge method: Lay aside period of time when lithium battery need not hind, enter dormancy state, right now use time shortens gradually. Lithium battery activation is very simple nevertheless, need to undertake only 3 - fill discharge normally 6 times to be able to activation circularly batteries, return to normal capacity. About charging time, we suggest everybody abides by the directive on product manual to undertake operating. Lithium battery stops automatically in the metropolis after batteries is full of fill, of charger of report of nonexistent nickel last many hours " tiny stream stream " charge, charge for long to make the it is critical to fill discharge to protect circuit to lie for a long time margin of batteries wanders, the life to batteries can cause very big pare. Manual of Ni Kang camera charges the specification charges such, where is that discharge? Same cannot exceeding undertakes discharging operating. Excessive discharge is nickel batteries sheds the method that hand down likewise, at that time is to reduce memory effect, but this ionic to lithium cell is harmed somewhat however. Once brought about lithium ion because of excessive discharge with respect to somebody batteries voltage is too low, cannot switch on the mobile phone cause return customer service maintenance. Because of the design specific characteristics of lithium battery, it is injured more easily than nickel batteries. Should charge for long normally we are forced to use the time in the evening to undertake operating, but nightly voltage will be usually a few taller than by day, to the lithium ion of enervated also is a potential risk for batteries. Beautiful can camera manual charges the specification serves as coda, we emphasize lithium ion using a method correctly of batteries again: If ① batteries is long need not, charge please 70% the left and right sides is deposited at dry, shady and cool place. Nickel hydrogen batteries controlled again full amount to charge in March; Lithium battery controlled recharge in June; ② charges according to the time of manual standard and program, even if also should undertake before 3 times so, usually battery of card machine lithium is in 2 - 5 can be full of between the hour; ③ crosses low clew when equipment occurrence n when, should begin in time to charge as far as possible, do not want excessive discharge; The activation of ④ lithium battery does not need special method, in be used normally lithium battery can activation naturally. When last hope everybody is using digital camera and other number device can more the greatest potential that efficient, safe coming develops battery.
