What are the specifications of a Dell e1505 battery?
"The specifications of a Dell e1505 battery is that it is an Internal Notebook Battery. The technology is 9-cell Lithium ion, the Voltage Provided is 11.1V and the Capacity is 85Wh."
Which is better the 6600 mah or 4400 mah li-ion battery for a laptop?
It depends on the voltage. WH = Watt Henry, mAH = milliamp Henry, watts = amps * volts and milliamps= 1000 * amps. Thus the conversion is: mAH = 1000 * WH / V, where V is the voltage. I'm looking at the battery for my Dell Studio and it's rated 85WH and 11.1V. So it's 1000 * 85 / 11.1 = 7658 mAH, so in this case 85WH is better than 6600 maH. If we solve 1000 * 85 / V = 6600, we get V = 12.9. When converting from WH, the bigger the voltage the lower the mAH. So for voltages bigger than 12.9 V, 6600mAH is better than 85WH. Hope this helps.
