Four Questions Service

Batteries such treatment has not been improved due to be purchased separately, in general, new batteries (including compatible battery) are only eligible for 3 months or 6-month warranty period, if it is second-hand batteries, there will be approximately 7 days to 1 months the warranty period. Therefore, consumers in the payment be sure to ask before the battery warranty period and conditions, do not forget to ask for proof of purchase to the merchant (such as the invoice or a receipt stamped), HP pavilion dv9000 Battery and let the businesses indicate the battery warranty. Overall, the market supply of laptop batteries are mainly official website of the brand notebooks and maintenance of points, laptops, and other merchants and online shops. The official website of the brand notebook batteries and maintenance of point of sale positive for the original goods, and users can also enjoy the regular after-sales service, drawback is that prices generally higher; computer businesses in town are mostly stocked with all brand laptop batteries sales, the advantage of much cheaper price than the official website, inadequate quality of service vary widely, there are "Depot" was secretly "changing the core" phenomenon! Against such incidents, Sony, Dell, Asus and other manufacturers repair centers, said there is the problem laptop battery should be replaced as a whole, and should use the original batteries, regular service center does not provide repair (ie change of the "core" to activate, etc.) business. Recycling batteries will be centrally, there is no "Depot Maintenance" one said.HP pavilion dv9600 Battery This shows that the value service firms have to buy the regular product!
At present, the battery of the more common batteries based on combinations of two or three batteries as a set of batteries in series, and then 23 groups together in parallel (eg: 4-core = two strings of two and, 6-cell = Series 2 and 3). Then the battery mAh value is how come it? The answer was batteries mAh value × number of batteries in parallel batteries. For example, the use of B class of the two strings of batteries, and two 4-cell battery, the capacity is 4400mAh. Third. Count battery life
We can target based on the parameters of the battery is generally inferred battery life. Formula is: the battery voltage (V) × battery capacity (Ah) ÷ load power = battery time (hours). ASUS Eee PC1000HE with the standard battery, for example, its parameters are as follows: 6-core, 8700mAh, 7.4V. First, the battery capacity of the unit converted into Ah (1Ah = 1000mAh), which is 8.7Ah. Actual use, the small, the average power consumption is 13W. Well, according to formula, the small battery life time is 4.95 hours (7.4V × 8.7Ah ÷ 13W = 4.95 hours). It is worth mentioning that this estimate is very conservative way, in actual use, due to the application of different power consumption will produce a corresponding change, so the actual battery life is often higher than the values obtained by this formula. Of course, we can also use the Windows operating system comes with a "meter" or related to the battery management software to view (as shown in Figure 4), was informed that the battery life time (see any software to the battery life are the theoretical values, and The actual battery life there is a certain deviation).
Original, reliable, cost-effective, deputy factory Original battery quality assurance, but the price is very expensive (some profiteers in a very low price to consumers to sell the so-called non-mainstream original battery,HP pavilion dv8000 Battery this part of the battery probably is to refurbish the battery or the battery assembly, it is recommended you do not gain petty cheap, runs the risk). The brand is the budget, deputy plant cells of choice for small consumers, as most of the brand launched by Vice-plant products in the quality of basic energy and comparable to original battery, while the price is a lot cheaper. As for the assembly of the battery, although the price is cheap, but quality is poor, even the existence of potential safety problems, we recommend you not buy.
