Recent developments have produced a range of new environmentally friendly cathode active materials based on Lithiated transition metal phosphates for Lithium-ion applications.


ACER Aspire 5742 battery feature:

Battery Type:  Li-ion 
Voltage:  10.8V or 11.1V
Capacity: 48Wh / 6Cell
Weight:  364g
Property: ACER Replacement Battery
Color: Black


With the international Standard Control from R&D, Manufacturing and test, battery have passed CE, UL, ROHS, ISO9001, QS9000 and TS16949. It can fully charge/discharge at least 300-500 times.

The Fraunhofer technology uses an organic electrolyte and the cell voltage is 4 Volts. It is claimed that their the cell chemistry is more tolerant to abuse.


Lithium Sulphur is a high energy density chemistry, significantly higher than Lithium-ion metal oxide chemistries. This chemistry is under joint development by several companies but it is not yet commercially available. Lithium Sulphur cells are tolerant of over-voltages. The cell voltage is 2.1 Volts

When long time without using laptop, Keep it in standby or sleep mode. It can both save the power and extend the ACER Aspire AS5253G notebook battery life.

If without using notebook long time(more than 3 weeks) or found that your battery charge/discharge time become shorter and shorter, you have to fully discharge the battery before next time charge again.


One doesn't necessarily expect great things ergonomically from a laptop in this price range, but the NV51B05u proved a mostly pleasant surprise. The Chiclet-style keyboard with medium-throw keys has good tactile response, though the clicks have a hollow sound that cheapens the audible effect.

Are an eco-friendly trio. All three are pretty spirited, they can go from 0-60mph in less than 11 seconds. The E-Cell uses a pure ev design with lithium ion HP laptop batteries and electric motors. The E-Cell Plus uses lithium ion batteries and electric motors to drive the wheels but also features a petrol-powered engine to charge the batteries. The F-Cell uses hydrogen fuel cells to power the electric motors. Only the E and F have zero tailpipe emissions. Confused? Heck, so am I!!! The vehicles are also expected to come in the funkiest of colors.

While the basic technology is well known, there is a lack of operating experience and hence system design data with some of the newer developments which also hampers their adoption. At the same time patents for these different chemistries tend to be held by rival companies undertaking competitive developments with no signs of industry standardisation or adoption of a common product. (The original patent on Lithium Cobalt technology has now expired which is perhaps one explanation for its popularity).


These drawbacks are far out weighed by the advantages of Lithium cells and are now being used in an ever widening range of applications.
