Battery care

aptops

Unfortunately, nickel-metal hydride batteries extremely vulnerable: The water content at temperatures they lose heavily just before and beyond the freezing point of performance: The chemical reaction of oxygen and hydrogen is hindered. Moreover, like Ni-MH batteries are not when they are over-or total discharge: The limits of the chemical reaction are reached, a buffer zone should indeed actually prevent the worst. Since the DELL Studio 1537 battery is never completely “sealed” as oxygen and hydrogen are highly reactive and volatile elements, the battery loses it over time. Oxygen and hydrogen react with the metal components of the cell and the surrounding air, causing the Dell Latitude E6400 battery can lose depending on manufacturing quality rather quickly to capacity.

Care almost impossible

A care of the nickel-metal hydride batteries is hardly possible. Once it is damaged, will not help aeration measures: the battery is ready for the hazardous waste. Maintenance measures are prudent loading and discharge, which will not hit the limit. This means that the DELL Latitude D830 Battery should never fully developed and loaded. Unfortunately, here the Chargers are not necessarily helpful: A poor power management in battery charger, laptop, mobile phone and digital camera battery in the shortest possible time to do after less than 50 cycles, an end.

Sudden Battery Death: The lithium-based battery

The lithium-ion battery and its development, the lithium-polymer battery, are the most advanced form of commercially available batteries. Nearly all modern devices currently have a corresponding energy source. The advantages of this DELL XPS M1530 battery type are obvious: Unlike the No-Cd battery have no memory effect, unlike Ni-MH batteries, they are more robust in terms of ambient temperatures and loading errors. They also have a higher chemical stability and durability. The main reason for its current widespread use is the fact that they offer plenty of performance in a small space. This makes them perfect for use in laptops, digital cameras, PDAs and mobile phones.

The advantages of lithium-ion batteries to nickel-metal hydride-energy sources are in fact relatively small: Even a lithium-ion battery can not endure low temperatures. From -25 ° C is the lithium-ion battery circuit. Also, over and discharge can not stand the lithium-ion Dell Inspiron 1520 battery. It speeds up as the Ni-MH battery, the chemical aging. The Lithium.Ionen battery lives so assume he must be charged only briefly and at low load times hardly loses theoretical capacity, which should be another perfect reason for the use in laptops, cell phones and MP3 players.

Chemical reaction

Capacity loss is unfortunately still before: As with nickel-metal hydride battery ages, the cell chemically. The problem is that the built-in battery electrode of lithium-graphite compounds, or by charging cycles gradually dissolves. Sometime it is so far “washed out” that can not produce enough ions. Ions, electrically charged particles, are responsible for the voltage in lithium-ion battery. If the accounting value of the ion, is also the performance. Falls below these a certain value, the cell is unusable. This may be the problems arising within a few cycles of the case for years.
