With the development of technology there has been a lot of difference in the power or energy used by different devices. There are some devices which run on electricity, whereas the others need batteries to operate. There are these new high current portable electronic devices like the cameras which do not need batteries to work and thus the use of quality batteries is rising highly. These portable electronic devices which are easy to carry require...more
Duracell batteries are considered to be one of the top most and best quality batteries worldwide as it is capable of withstanding the climatic conditions around the globe and are even environmental free. The battery is fully covered with a metal body that prevents the leakage in or out of the cell. The performance that a Duracell battery gives cannot be compared to any other ordinary batteries in the market. Any Duracell rechargeable battery will...more
WHAT ARE LIPO BATTERIES AND WHY ARE THEY SO POPULAR IN THE RC WORLD?LiPo batteries are a type of rechargeable battery that has taken the electric RC world by storm, especially for planes and helicopters. They are the main reason electric flight is now a very viable option over fuel powered models.The lithium-polymer differentiates itself from conventional battery systems in the type of electrolyte used. The original design, dating back to the 1970s, uses a dry solid polymer electrolyte. This electrolyte resembles a plastic-like film that does not conduct electricity but allows ions exchange (electrically charged atoms or groups of atoms). The polymer electrolyte replaces the traditional porous separator, which is soaked with electrolyte.AdvantagesVery low profile - batteries resembling the profile of a credit card are feasible.Flexible form factor - manufacturers are not bound by standard cell formats. With high volume, any reasonable size can be produced economically.Lightweight - gelled electrolytes enable simplified packaging by eliminating the metal shell.Improved safety - more resistant to overcharge; less chance for electrolyte leakage. LimitationsRC LiPo batteries are still...more
In the earlier days, the Duracell rechargeable batteries were used among the professionals such as sound technicians, police department and hospitals. The Duracell AA size batteries available in the market are the type of non-rechargeable batteries. They have long lifespan and use the alkaline technology. The features of Duracell rechargeable...more
Lithium batteries are very popular now due to its competing technology and has certainly reduced the good old alkaline battery. Lithium has the highest specific energy of all and is much lighter than other types of rechargeable batteries of the same size. They have a longer life than the other batteries, to say it last more than 3 times the...more
NiMH battery is the shorthand used for Nickel-Metal-Hydride battery. These batteries are similar to the nickel-cadmium batteries with the difference of using cadmium as an active element at the hydrogen absorbing negative electrode. The main components of NiMH batteries include a Nickel-hydroxide cathode, the anode of hydrogen absorbing alloys and an electrolyte of Potassium-hydroxide. This electrode is composed of a metal hydride containing the alloys of Lanthanum which serves as a solid source of reduced hydrogen. This is oxidized to form protons. The electrolyte developed is of the alkaline potassium hydroxide.The voltage of NiMH battery is 1.2 volts. The density of this battery is more than the double of the Lead acid and about 40% more than NiCd battery. These batteries are prone to memory effect although to a less extent. They are better for the environment because no mercury or lead is used. The costing of NiMH batteries is more than that of Lead-acid and NiCd batteries.It has been demonstrated that there are up to 3000 cycles at 100% depth of discharge by using NiMH batteries. These batteries can tolerate over charge and discharge conditions. They have low impedance....more
Rechargeable AA batteries almost always make economic sense. There are various types of rechargeable AA batteries and their capacity varies with the technology used. Rechargeable AA-sized batteries based on Li-ion chemistry have also been...more
The holiday season is the best time for poster printing. There are plenty of advantages for small and large businesses alike when they invest in a little poster printing at this time. Do not believe me? Well, let me spell out to you the...more
ECC or Error Correction Codes and is a method utilized to correct and detect errors initiated during transmission or storage of data. Certain types of RAM or Random Access Memory chips within a computer apply this strategy to right data errors and...more
In Linux operating system, the hard drive volumes are mounted by the disk labels, in place of the device paths. It is a quite effective approach because the disk path and name can get changed when you boot your system and so can create...more
