The following is a post I found a few months ago about a rechargeable Lithium batteries for notebook computers. I've tried to e-mail and regular-mail the sender of this post for addition infomation about these batteries. I am interested in knowing what sizes these batteries are, what computers do there fit in, how much do they cost, where can I find/order them, and after 200 charging cycles to what degree does their performance degrade? Thanks in advance, Anita Krajnc (Internet: akrajn@epas.utoronto.ca). >Article: 3433 of comp.sys.laptops >Newsgroups: comp.sys.laptops >From: dima@redox.quorus.e-burg.su (Dmitry Kargapolov) >Subject: New chargeable litium battery ... >Reply-To: dima@redox.quorus.e-burg.su >Organization: JSC >Date: Tue, 23 Jun 92 12:09:35 +0600 > > INFORMATIVE COMMUNICATION > > Trying to increase the in-service time of Notebooks > OPLUS Company has developed a new rechargeable litium battery with > high specific properties, permitting to approach the computer's > off-line mode in-service time, meeting the consumers' requirements. > > The rechargeable litium battery capacity is higher than > that of the best rechargeable nickel-cadmium batteries by 900%. > The table provides the data on the in-service time of the Notebook > on the basis of the CPU 80286 with the employment of > nickel-cadmium and lithium batteries. > > -------------------------------------------------------- > : Rechargeable : Nominal : Nominal : Average : Battery : > : battery pack : Voltage : Capacity: Weight : Life : > : : (V) : (Ah) : (g) : (Hours) : > -------------------------------------------------------- > : : : : : : > : Ni-Cd : 9.6 : 2.25 : 500 : 2.3 : > : : : : : : > : RPS1004 : 9.6 : 20.4 : 500 : 20.4 : > : : : : : : > -------------------------------------------------------- > > RPS1004 rechargeable battery service life consists of > 200 cycles without changing the residual capacitance.
