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.

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.

（）产生的磁场
交变磁场的励磁电流是电感励磁电流和电压的分支，在接近度的电流的相位滞后。由于电机转动力矩充分，应具有足够强的磁场，磁化能力磁化曲线充分利用了铁芯材料的“硅”表达式，让磁通达到了高磁通密度。然而，当磁通密度接近饱和磁通密度、励磁电流的有效值和非线性电流明显增加，峰值，和铁心的损耗明显增加，从而影响电机的性能。因此，磁通密度的设计要适当，交流电源使用电压不应超过额定值太多。
例如：额定电压、励磁电流约的额定电流。
（）负载分支将电能转化为机械能
这里我们只讨论转子电机的转动部分是稳定的旋转，当机械功率输出轴转角的增大，负载等效电路功耗分支增加，有功功率是由相应的阻力的体现。
然而，“电机绕组（线圈”）是电感，定子绕组和转子（旋转体）的磁场线缠绕，不是所有的每一点，有的磁回路的一部分，称为“漏”和“感应磁漏”在负载支路对应的系列。
（）交流感应电机
两支路功率因数电感电流：
励磁电流的支路电流是非线性的，这是输入电压有关；
当负载电流仅用于分析稳定的速度，它的输出功率有关。
额定工作条件下，功率因数约为。
（）交流感应电机分为线性负载”
交流感应电机分为“线性负载”的标准，其原因是：从现实来看，励磁电流比较小，只有的总会计。zui重要的是，的输出电感负载具有大容量，足以吸收谐波电流。
负载性质不同的不同措施
的输出必须有一个电容，电容的大小，对的负载特性的优点得失有很大关系。
（）在通信的输出电容器是基于非线性负载
限制输出电压波形畸变
电容滤波整流器的输入电流波形的脉冲宽度较窄，其输出端口电容器主要是限制输出电压波形失真不超过。
降低逆变器输出
电容滤波整流谐波电流电流变非线性负载功率因数，虽然只有，但要注意的是，这是由谐波电流引起的，谐波频率高，基波频率好几倍，滤波器比较小。在输出端的电容旁路谐波电流，电感可以限制谐波电流，功率晶体管的电流有效值也相应减少，相应减少了功率损耗，散热容易，降低了成本，提高了效率。
为线性电阻负载，逆变器的工作状态基本上是非线性负载条件相同。
“沟通”这两种载荷，是一个非常专业、经济、实用的品种。
（）感性负载
感性负载的功率因数，逆变器的输出电流，输出端口与大电容器的电容电流的感应电流广告提供，如果电容器*可以提供“感性负载电流，逆变器的设计可以是zui小的。
例如：负载的功率因数电感，是有功电流是额定电流的；可以作为感性无功电流额定电容器的电流为；如果大容量的选择，电容器的电流达到额定电流的。此时，逆变器必须承担的有功电流，即的额定电流，逆变器可以设计得更小。
这是“*”的感应功率因数设计。然而，当其他负载，如电阻、电容、设备的利用率很低。
（）通用协调需要考虑多个负载特性
各种负载电容对输出端口有不同的要求：电流大的电容补偿电感的电感性负载，电感反馈能量，限制电容器不宜过小；
