The FAQ To Dell Laptop Battery

All rechargeable batteries are depleted with use and over time. As time passes and use increases, performance decreases. For a typical user, from 18 to 24 months there will be a considerable reduction in operating time. For advanced users, reducing the operating time will be observed before 18 months. We recommend buying a new Dell battery when the time does not fit your needs.

Generally, a higher value of watts per hour (W / h) in the same system and under the same conditions gives a running time longer. For example, for the same system, running the same applications, a battery of 53 W / h gives a running time approximately 65% higher than a battery of 32 W / h. Dell takes as reference the industry standard benchmark for the demands of running time of batteries.

There are multiple factors affecting operating time can provide a laptop battery before it needs recharging. These factors include the configuration, processor, memory and so on. The types of applications that are running and the brightness of the screen. For more information on running times and the benchmark battery, see “Understanding the battery life of portable computers” online.

The battery charges when the computer is connected to an AC power source via the AC adapter. A Charging time varies depending on the system. If your system supports ExpressChargeTM, drums exceed 80% charge in one hour and will be fully recharged in two hours with the system off. In a system with ExpressChargeTM function, the battery usually exceed 80% charge in one hour and will be fully recharged in two hours with the system off.

You should remember that no loading and unloading extend the life of a battery with lithium ion technology. The battery is designed for the loading process stops once it is completed. It is easy to install a battery. First, make sure to save all open files. Then plug the AC adapter directly to the laptop or set the system hibernate or unplug it. Actuate sure you are using the battery and install just the battery.

Dell has a rigorous qualification process by which all Dell batteries are validated to ensure continued, adequate performance and security. In the market batteries from other manufacturers that claim to be compatible with Dell systems. Dell can not guarantee the veracity of these claims or whether it is safe to use on Dell systems. Dell strongly encourages its customers to use only Dell batteries listed for your model of laptop.

Only Dell batteries are warranted for 1 year, are designed for optimal performance and security on Dell systems and have the Dell technical support during the warranty period.

Take Care Of Notebook Batteries

Take Care Of Notebook Batteries

Cells Lithium Ion battery can be drained or explode if heated to temperatures above 60 degrees, or if they are loaded beyond their power limit. Another problem is that the cells are rapidly oxidized when they are fully discharged, which demands close attention if the battery is completely depleted. To make reliable batteries, all Li-Ion batteries used commercially have some sort of intelligent circuit that monitors the battery charge. This stops charging when the battery voltage reaches a limit and stops the supply when the battery is discharged, in order to avoid discharge.

Another interesting question, especially notebooks, is that the batteries are composed of 3-9 independent cells. The circuit is monitoring the voltage of individual cell, but only the set. This means that in situations where the cells are out of balance, or in cases where a cell is defective premature, the circuit interrupts the power supply after a short time of use. Then come the many cases where a battery that originally lasted 2 hours, 15 minutes passes last, for example.

In most notebooks, the battery circuit works in conjunction with the BIOS of the motherboard, which creates a possibility of various errors. Commonly, after several partial loads, the monitor is out of balance BIOS and go to calculate the capacity of the battery the wrong way. Then whenever you are making partial refills, which will make the battery last less and less, although the cells remain perfectly healthy.

This is why so many notebooks include utilities to “calibrate” the battery, available in the setup. This tool performs a charge and discharge cycle complete, updated measurements. When you leave it unused, Li-ion batteries deteriorate faster when fully loaded or unloaded, therefore, it is best to leave the battery with a 40% load. Heat also speeds up the process, therefore, the colder the environment, the better. A fully charged battery, stored in an oven at 60 C, you may lose more than 40% of its capacity after only 3 months, while a battery retains the 0 C, with 40% load, will lose only 2% after one year.

Avoid discharging the battery when not needed. The best thing is simply to use and charge battery according to its cycle of use. Another tip is that the battery life is less when subjected to fast downloads, so burn DVDs with the notebook using the battery power is not a good idea. Every 20 or 30 cartridges, it is interesting to make a complete cycle of loading and unloading, in order to “calibrate” the measurements of the chip and the BIOS monitor.

At first, removing the battery from a laptop that is connected to making the most of the time would be a good idea to increase its life. The problem is that most notebooks use battery and surge protection from the mains. Removing the battery, this protection is lost, which can shorten equipment life.
