What is sulfation of batteries?
Sulfation is the formation or deposit of lead sulfate on the surface and in the pores of the active material of the batteries' lead plates. If the sulfation becomes excessive and forms large crystals on the plates, the battery will not operate efficiently and may not work at all. Common causes of battery sulfation are standing a long time in a discharged condition, operating at excessive temperatures, and prolonged under or over charging.

感性負載

Batteries are divided in two ways, by application (what they are used for) and construction (how they are built). The major applications are automotive, marine, and deep-cycle. Deep-cycle includes solar electric (PV), backup power, and RV and boat "house" batteries. The major construction types are flooded (wet), gelled, and AGM (Absorbed Glass Mat). AGM batteries are also sometimes called "starved electrolyte" or "dry", because the fiberglass mat is only 95% saturated with Sulfuric acid and there is no excess liquid. Flooded may be standard, with removable caps, or the so-called "maintenance free" (that means they are designed to die one week after the warranty runs out). All gelled are sealed and a few are "valve regulated", which means that a tiny valve keeps a slight positive pressure. Nearly all AGM batteries are sealed valve regulated (commonly referred to as "VRLA" - Valve Regulated Lead-Acid). Most valve regulated are under some pressure - 1 to 4 psi at sea level.

What is the "Memory Effect" that I have heard about?
NiCad batteries, and to a lesser extent NiMH batteries, suffer from what's called the "memory effect". What this means is that if a battery is repeatedly only partially discharged before recharging, the battery "forgets" that it has the capacity to further discharge all the way down. To illustrate: If you, on a regular basis, fully charge your battery and then use only 50% of its capacity before the next recharge, eventually the battery will become unaware of its extra 50% capacity which has remained unused. The battery will remain functional, but only at 50% of its original capacity. The way to avoid the dreaded "memory effect" is to fully cycle (fully charge and then fully discharge) the battery at least once every two to three weeks. Batteries can be discharged by unplugging the device's AC adapter and letting the device run on the battery until it ceases to function. This will insure your battery remains healthy.

Do I need to charge my new Laptop or Notebook battery?
A new battery comes in a discharged condition and must be charged before use (refer to the devices manual for charging instructions). Upon initial use (or after a prolonged storage period) the battery may require three to four charge/discharge cycles before achieving maximum capacity. When charging the battery for the first time the device may indicate that charging is complete after just 10 or 15 minutes. This is a normal phenomenon with rechargeable batteries. Remove the battery from the device, reinsert it and repeat the charging procedure.

Do I have to condition my Laptop or Notebook battery?
Yes, it is very important to condition or fully discharge and then fully charge the battery every two to three weeks. Failure to do so may significantly shorten the battery's life (this does not apply to Li-Ion batteries, which do not require conditioning). To discharge, simply run the device under the battery's power until it shuts down or until you get a low battery warning. Then recharge the battery as instructed in the user's manual.

My new laptop battery is not Charging. What is wrong?
New batteries are shipped in a discharged condition and must be charged before use. We generally recommend an overnight charge (approximay twelve hours). Refer to the user's manual for charging instructions. Rechargeable batteries should be cycled (fully charged and then fully discharged) two to four times initially to allow them to reach their full capacity. (Note: it is normal for a battery to become warm to the touch during charging and discharging).

New laptop batteries are hard for the device to charge; they have never been fully charged and are therefore "unformed". Sometimes the device's charger will stop charging a new battery before it is fully charged. If this happens, remove the battery from the device and then reinsert it. The charge cycle should begin again. This may happen several times during the first battery charge. Don't worry; it's perfectly normal.

Is it Possible to Upgrade the Device's Battery to a Newer Chemistry?
NiCad, NiMH and Li-Ion are all fundamentally different technologies and cannot be substituted for one another unless the device has been pre-configured from the factory to accept more than one type of rechargeable battery. The difference between them stems from the fact that each technology requires a different charging pattern to be properly recharged. Therefore, the portable device's charger must be properly configured to handle a given type of rechargeable battery. Refer to your owners manual to find out which rechargeable battery types the particular device supports or use our QuickFind search engine to find the device in our database. The database will automatically list all of the battery types supported by the machine.

（）產生的磁場
交變磁場的勵磁電流是電感勵磁電流和電壓的分支，在接近度的電流的相位滯后。由于電機轉動力矩充分，應具有足夠強的磁場，磁化能力磁化曲線充分利用了鐵芯材料的“硅”表達式，讓磁通達到了高磁通密度。然而，當磁通密度接近飽和磁通密度、勵磁電流的有效值和非線性電流明顯增加，峰值，和鐵心的損耗明顯增加，從而影響電機的性能。因此，磁通密度的設計要適當，交流電源使用電壓不應超過額定值太多。
例如：額定電壓、勵磁電流約的額定電流。
（）負載分支將電能轉化為機械能
這里我們只討論轉子電機的轉動部分是穩定的旋轉，當機械功率輸出軸轉角的增大，負載等效電路功耗分支增加，有功功率是由相應的阻力的體現。
然而，“電機繞組（線圈”）是電感，定子繞組和轉子（旋轉體）的磁場線纏繞，不是所有的每一點，有的磁回路的一部分，稱為“漏”和“感應磁漏”在負載支路對應的系列。
（）交流感應電機
兩支路功率因數電感電流：
勵磁電流的支路電流是非線性的，這是輸入電壓有關；
當負載電流僅用于分析穩定的速度，它的輸出功率有關。
額定工作條件下，功率因數約為。
（）交流感應電機分為線性負載”
交流感應電機分為“線性負載”的標準，其原因是：從現實來看，勵磁電流比較小，只有的總會計。zui重要的是，的輸出電感負載具有大容量，足以吸收諧波電流。
負載性質不同的不同措施
的輸出必須有一個電容，電容的大小，對的負載特性的優點得失有很大關系。
（）在通信的輸出電容器是基于非線性負載
限制輸出電壓波形畸變
電容濾波整流器的輸入電流波形的脈沖寬度較窄，其輸出端口電容器主要是限制輸出電壓波形失真不超過。
降低逆變器輸出
電容濾波整流諧波電流電流變非線性負載功率因數，雖然只有，但要注意的是，這是由諧波電流引起的，諧波頻率高，基波頻率好幾倍，濾波器比較小。在輸出端的電容旁路諧波電流，電感可以限制諧波電流，功率晶體管的電流有效值也相應減少，相應減少了功率損耗，散熱容易，降低了成本，提高了效率。
為線性電阻負載，逆變器的工作狀態基本上是非線性負載條件相同。
“溝通”這兩種載荷，是一個非常專業、經濟、實用的品種。
（）感性負載
感性負載的功率因數，逆變器的輸出電流，輸出端口與大電容器的電容電流的感應電流廣告提供，如果電容器*可以提供“感性負載電流，逆變器的設計可以是zui小的。
例如：負載的功率因數電感，是有功電流是額定電流的；可以作為感性無功電流額定電容器的電流為；如果大容量的選擇，電容器的電流達到額定電流的。此時，逆變器必須承擔的有功電流，即的額定電流，逆變器可以設計得更小。
這是“*”的感應功率因數設計。然而，當其他負載，如電阻、電容、設備的利用率很低。
（）通用協調需要考慮多個負載特性
各種負載電容對輸出端口有不同的要求：電流大的電容補償電感的電感性負載，電感反饋能量，限制電容器不宜過小；
