Battery newcomers boast of miracles batteries which were running very high energy density, process 1000 charge / discharge cycles and are paper thin. Such properties are certainly achievable, but not in one and the same laptop battery.

A certain battery may be built for small size and big performance, but this Dell Inspiron 1501 Battery is a highly limited life expectancy. Another battery may be constructed for long life expectancy, but it is thick and bulky. A third battery can have a high energy density and long life expectancy, but it is prohibitively expensive for the consumer.

Battery manufacturers know customers’ needs and offer batteries that meet these requirements best. The mobile phone industry is an example of this clever adaptation to the market. Here, have small dimensions and high energy density compared to the advantage of long life expectancy. Short life expectancy here is not a problem because the devices are replaced before the Dell Inspiron 6400 Battery is worn out.

Let’s look at different battery types, beginning with nickel-metal hydride. The cylindrical nickel-metal hydride batteries have an average energy density of 80Wh/kg and allow an estimated 400 cycles. The prismatic nickel-metal hydride Dell Inspiron 640m Battery is designed for slim geometry and agreed energy density and number of cycles. The battery is estimated to be moderate 60Wh/kg and offers approximately 300 cycles. Especially long-lasting nickel-metal hydride batteries for industrial purposes are constructed as cylindrical cells and revealed modest 70Wh/kg, but are designed for approximately 1000 cycles.

Lithium-ion batteries can be built for different energy densities in a similar manner. To pack more energy in a cell at the expense of safety. While commercial lithium-ion Dell Inspiron 1420 Battery have good security, which are super-high-capacity lithium-ion batteries for safety reasons not made available to the general public.

The following is a summary of the strengths and limitations of today’s popular batteries. Although the energy density has the priority, there are also some other important issues such as life expectancy, charge characteristics, maintenance expenses, self-discharge and operational costs. Since nickel-cadmium Dell Latitude D830 Battery are still considered to be standard for comparisons, we will evaluate different chemistries against this classic battery type.

Nickel-cadmium — mature, but has only moderate energy density. Nickel-cadmium is used where emphasis is placed on a long life expectancy, large Entladekoeffizienten and wide temperature range. Important applications include radios, medical equipment and tools. Nickel-cadmium containing toxic metals.

Nickel-metal hydride — offers a greater energy density than nickel-cadmium, but has a shorter life expectancy. Does not contain any toxic metallic Sunstanzen. Applications include wireless telephones and laptop computers.

Lead Acid — cheapest solution for larger installations, where the weight does not matter. Lead-acid Inspiron E1505 Battery is mainly used in hospitals, for wheelchairs, emergency power and lighting unterbruchsichere meals.

— Lithium-Ion batteries with the greatest growth potential. Offer high energy density with low weight. Protection circuits are needed to limit voltage and current for safety reasons. Applications include notebook computers and cellular phones.

Lithium-polymer — Similar to lithium-ion, Dell Latitude D520 Battery , slim build, this system allows in a simple construction, but at higher cost for watt-hours. Main applications are cellular phones.

-Reusable alkaline batteries — your limited number of charge cycles and the low charging current to be compensated by a long shelf life, which makes the battery for portable entertainment devices and flashlights ideal.
