dell laptop battery

Batteries are perishable goods, the collapse of the manufacturing process begins when you leave. With simple preventive measures, the user can, however, the aging process Dell Inspiron 1525 battery slow. This article gives some guidelines on how that can be reduced with the aging related loss of capacity, and how new and stored batteries formats, respectively. should be prepared.

The recommended storage temperature for most batteries is 15 ° C. While lead acid batteries must be recharged more fully, nickel and lithium-based batteries should be stored at a 40% state of charge (SoC). This charge reduced most associated with the aging of the capacity loss, and keeps the Dell Inspiron 1545 battery still in good working condition. Figure 1 illustrates the recoverable capacity over a year, in dependence of different storage temperatures and loading conditions.

High charge levels and elevated temperatures hasten the capacity loss.

In the family of lithium-ion Dell Vostro 1520 battery offer a small advantage over cobalt-manganese (spinel) in terms of higher storage temperatures. Even with nickel-based batteries dell xps m1330 battery is the impact of higher storage temperatures negatively, but to a lesser degree than lithium ion.

Most of today's laptop computers are powered by lithium-ion batteries. During operation, the temperature rise inside the Dell Inspiron Mini 9 battery compartment of a laptop at about 45 ° C. The combination of high charge state and the increased ambient temperature has a negative effect on the battery. This explains the comparative short life expectancy of many laptop batteries.

Sealed lead acid batteries can be stored for up to 2 years. A periodic charge, also called 'Refresh' / refresher charge is necessary to prevent the cell voltage falls below 2.10V (Some lead-acid batteries allow somewhat lower voltage level). Dell Vostro 1500 battery charge Insufficient leads to sulfation, a  on the negative plate, which impedes the current flow during charge and discharge. A full charge and / or regeneration can sometimes correct early in the loss of capacity.

Priming new batteries

The manufacturers recommend a slow charging of nickel-based batteries for 24 hours for brand new batteries and those that have been stored for long periods. Such maintenance brings all cells to an identical state of charge and distributes the electrolyte in turn on the dry spots caused by the gravity of the electrolyte. It is advisable to check before using the battery capacity with a battery analyzer. This is especially important in critical applications.

Cyclic format is recommended in order to compensate for a loss of capacity, which can in nickel-based batteries after storage for 6 months or more occur. This is achieved through a DELL Latitude D620 battery charge slowly, followed by one or more discharge / charge cycles. The recovery rate is determined by the circumstances under which the battery was placed in storage. The longer the storage and the higher the storage temperature was, the more cycles are needed. The program of the Prime Cadex battery analyzer automatically performs the necessary number of cycles to reach maximum capacity.

Nickel-based batteries are not always fully formatted when they leave the factory. The implementation of multiple charge / discharge cycles, either in normal use or with the aid of a battery analyzer completes the formatting. The number of cycles required to achieve the maximum capacity is different, depending on the cell manufacturers. Cells reach the quality specifications after 5 to 7 cycles. Insufficient formatting can take 50 or more cycles until an acceptable capacity level is reached.

What is the difference between 'priming / preparation' and 'Format forming /' is? For the user, both terms mean that insufficient capacity was found. The difference can be explained that the format only once when the battery is brand new, must be carried out during the preparation should be done several times and each time after a prolonged storage of the Dell Inspiron 1720 battery.

Lithium-ion batteries to start as soon after the first charge at full capacity. The manufacturer of lithium-ion cells to stress that no formatting is necessary. Nevertheless, a formatting control  and useful as the battery power can be. An excessive number of cycles should be avoided due to wear or the effect.
