Learn the details about laptop battery

Use rechargeable batteries for laptops, one of the advantages of the desktop, it can greatly facilitate a variety of environments using laptops. Introduced the first VGP-BPS2 VGP-BPS2A battery is nickel cadmium batteries (NiCd) battery but has a “memory effect”, each charge is required before the evacuation, very easy to use, and soon found himself nickel-metal hydride battery (NiMH ) replaced, NiMH not only failed to “memory effect”, but can do more per unit weight of 10% of electricity. The battery most commonly used is lithium-ion battery (Li-Ion), it is also ineffective “memory, compared to NiMH per unit of weight gain more power, the price two times higher than the NiMH . In the same weight, these three kinds battery is 1:1.2:1.9 ratios.

Notebook batteries currently used in three main categories: 1. Nickel-chromium batteries, 2. Ni-MH battery, 3. Lithium, they are generally expressed as: Ni-Cd Ni-Cd, Ni-MH Ni-MH, lithium-ion battery LI.

The purchase or replace the battery when the laptop for many users, “battery” may be unfamiliar. At the outset, batteries and batteries are two concepts. A battery is composed of several slightly bigger than your thumb, cylindrical, up to about 7.8 cm, the voltage is 3.6V small units, a professional name that is called 18650, Sanyo and Samsung is the first manufacturer in China. Batteries as a small GK479 U4873 battery, thanks to the combination series, that is, we see that the battery a. Then talk about how to judge the battery are several nuclei:

One way: Disconnect the battery for the number of contacts to see, there are a few tens of cores. But it is a “minister” approach. Let’s take a look at “Cao Chong” is how, “said the elephant”: the look of your battery nominal number of v, such that 14.4v, then divided by 3.6 to 4, then turned out to be four batteries together in series. And then take a look at the capacity of the battery pack, for example 4400mAh, then prove that the two aforementioned sets of batteries in series, because the battery capacity is low for 2000 — 2200mAh or more, and together the two groups can be achieved must be 4400mAh. In both cases, the battery is 4 × 2 = 8 cores.

The composition of laptop battery

Notebook battery from the shells, printed circuit boards and batteries belonging lithium ion battery. People talk about batteries in general refers to the number of batteries in the battery mAh refers to the ability of the laptop battery.

Mainly by the protection circuit (or the secondary circuit protection), and the capacity of the circuits in two parts, the laptop PP2182D PP2182L battery charge and discharge management and safety.

Time Laptop Battery standby mainly by the value mAh decide. Under normal circumstances, a little more battery, the mAh value is greater than longest standby time. Battery life for notebook mainly by the charge and discharge times to measure the quality of the products is generally eligible to 500-600 times. Therefore, efficient use of laptop batteries within two years expired the battery is aging, standby affect the strong decrease of the mobility of laptops.

Abstract:

Most laptops today use lithium batteries, in which over 13 inch notebooks, especially over high capacity 6-cell battery, while the 13-pad of thumb to ensure portability, many products have chosen the 3-pin thin around the battery. To get the most A1185 A1045 battery life of portable, many manufacturers have started to develop fuel cells, I believe that sooner or later we can see the production version of the fuel cell, then you really can-office Portable weather.

Digital Camera Battery maintenance tips

For a digital camera battery, the length of using time, not only relate with the quality, power, in fact, the user’s operation also has great relevance. Most photographers are accustomed to place the camera inside the camera bags after use, or placed inside cabinets, batteries are not out to save individually, this approach sounds like no problem, but not conducive to Dell Inspiron 1420 battery protection.

Generally speaking, if you do not use the camera more than 15 days, then best to remove the battery from the camera to separate storage, preservation of the environment is best dry and shady place, and do not store the battery together with metal objects.

According to our survey, currently in the market the majority of digital cameras use lithium batteries, it is relatively easy storage. The only caveat is that if not used for a long-term, preferably at intervals of 2 months, once to activate the hp PP2182L battery, that is, charge and discharge, this can effectively extend battery life.

As for the Ni-MH battery, the memory effect will reduce the total capacity of the battery and the using time, and as time goes on, stored charge will get less and less, the battery also will be consumed faster and faster. Therefore, we should try to recharge after power all used up, each charge must be sufficient.

If you go out and temporary use the alkaline batteries, you must remember taking out in time, or else if not used for a long time, the battery is easy to corrupt circuit, the camera could not escape the scrapped destiny . 

About the rechargeable Ni-MH batteries and lithium batteries, for just bought back the general power is very low or no power, the first charge must be adequate. Lithium sony VGP-BPS2 battery charging time are generally more than 8 hours, while the Ni-MH battery charging time are generally more than 16 hours. To achieve the best results, that is, the battery reached its maximum power, there are generally three or more times repeated charge-discharge. Battery tends to be more heat after charging, it is best to be cooled and then loaded camera battery.

However, note that the lithium batteries don’t have memory effect, so do not discharge, otherwise it will destroy the battery structure, and loss of battery life.

In addition, in order to avoid the loss of electricity, remove the battery after charge, do not let the battery poles in contact with conductors at the same time, for example, do not use your fingers at the same time at both ends of the battery contacts. The lithium batteries users should try to keep the camera battery box battery positive and negative contact points clean, if necessary, you can use a dry cloth gently wipe the swab and then install the battery.
