lithium battery pack by using different materials and processes as well as rigorous quality control to varying degrees, but it was a big difference. In particular, greater price difference. The prices between high and low are almost twice.
Why is there such a difference in Na? So why lithium iron batteries will be so good cheer? Where is the difference? How to choose?
lithium battery pack  The production of lithium-iron battery and environmental requirements of the production process are more stringent, a neglect of non-performing rate slightly will improve immediately reduce the price it had lower standards. Because of this, some grade B or C grade will flow on the market. As lithium-iron Dell Inspiron 1501 battery is still a relatively new, many buyers today do not know whether it is also, therefore, wishes to provide some distinguishing features of this method and the importance of the battery for your reference.
lithium battery pack  is good or bad judgments, the most basic points that can be analyzed from the following:
1. Uniformity
Battery harder to do is homogeneous, but the largest chain of battery is also homogeneous. If the 10 batteries strung, there is a first to arrive on-protection standards of the discharge, while several others are still plenty of power, this string of hp 361742-001 battery pack that can power capability is not all over low? Were made with a first place is the same reasoning.
The inconsistency of the battery without the added protection board is very easily broken, it is easy to overload or excessive discharge; have unprotected board sony VGP-BPS2A battery pack may be using more electricity capacity will also be more weak. There is also a lot of battery factory launched the production of batteries, but it was not necessary for the chain of causes product group. And the whole manufacturing process is very strict to achieve uniformity in controlling.
Simple Test Method: Series 4 batteries, so 1C and 3C charge-discharge, and the concept of charge-discharge process of the investigation, the battery voltage to see if differences in the lifting of the situation will. It is better to do 4 to 5 times.
2. lithium battery pack  Self-discharge rate
Lithium iron battery self-discharge rate, the theoretical value must be less than 2% per month over this value is not a good Dell 75UYF battery. Not a problem in the method is to use the material in question.
Low-rate self-discharge has always been the characteristics of lithium-iron battery, if self-discharge rate, when you install finished goods delivered to customer sites, he had no power, and customers feel? And a lot of energy wasted.
Channel in the group context, it will affect the balance of the hp PB992A battery, the battery can be installed less, and that the battery life is reduced.
Method of simple test: take roughly equal to the capacity of the battery 10, the congestion charge put aside for a month after switching on, then measure the value of the ability to calculate the self-discharge rate. (The sets aside a call after that amount of voltage value, what changes in battery voltage.)
3. Charge-discharge rate (load C-rate)
Quick charge and discharge is actually a lithium-iron batteries, one of the most advantageous because of its fast charge and discharge, which has very similar characteristics and a super capacitor but its super-capacitor capacitor important than hundreds of times. If the charge-discharge characteristics sufficiently rapid, the use of lithium-iron apple A1079 battery is not very meaningful.
In general, the charging rate of good quality lithium-iron battery is 3C (about 20 minutes power saturation charge), while the speed can reach 30 degrees centigrade. Special needs can achieve a higher magnification of the charge and discharge. The above situation is quite the battery life is the premise.
Method of simple test is, in order to manufacturer specifications can be used to test the maximum load, the rate of discharge, if the testing process, the cells fire very serious, then the quality of BTP-43D1 batteries n is not very good.
4. lithium battery pack  Stages
In general, the user can not be measured, and can only trust the data supplied by the manufacturer or appointed by a professional unit on behalf of the measure. Good quality lithium-iron batteries, in 3000 the use of 1C charge cycles and discharge its electricity capacity; mitigation will be less than 15%.
In short, the lithium iron Dolphin alone, the problem spots are not large, but after the series parallel connection to use and the features described above should give special attention to the. Especially in the high strings high voltage VGP-BPS2B batteries power capacity in the group, but also pay particular attention to the quality of batteries.
