I believe the reason the battery life has increased beyond what I though possible is due to how some Lithium-Ion batteries work. The higher the resistance (amps), the lower the battery life (mAh). According to NHC, my laptop draws an average of about 17 watts from the battery. Watts = Amps * Volts. So 17w / 14.8v = 1.15a. With the original battery, The 1.15 amp load was divided into two 14.8v series (four 3.7v cells per series). This gave a load of 0.575 amps per series. Now the load is divided into 4 series of 4 cells each (16 cells total). This brings the load down to 0.2875 amps per series. I'm guessing that higher amp requirements caused these batteries to lose their mAh rating much faster than a lower amp requirement. With the amps now spread out between 16 batteries (0.072 amps per battery), this is allowing the cells to produce optimal performance. This idea comes from a chart posted in this thread (page 2). Note the results for the two 3000mAh cells.
I could be totally off on my theory, but whatever the reason is for the great battery life, I am very happy to have such great results.
Next project..... adding a third battery! How will 24 cells work? 28 cells? I'm hoping to find out.
