Re: Laptop Battery Question
no
Volts * Amps = Watts 85W / Watts = How long the battery will last I believe. |

Re: Laptop Battery Question
It means that if your laptop needs 1w an hour it will last for 85 hours.
it will last waaay more than an hour in your laptop, aprox 4-5 hours at a guess. the lower 65Whr battery will last upto about 2-3 hours i'd guess. exact figures could be given if i could find somewhere how much power the laptop needs

Re: Laptop Battery Question
standard laptop batteries can run for upto 2 hrs on average (depending on how you use the computer). Turn the speaker volume up, turn the LCD backlight up and run multiple apps will drain your battery faster.

Re: Laptop Battery Question
Energy Density
The amount of energy that can be contained in a specific quantity of the fuel source. Typically quoted in watt-hours per pound, wh/lb, or watt-hours per kilogram, wh/kg. For example, flooded lead-acid batteries generally have about 25 wh/kg, the latest advanced lead-acid designs claim about 50 wh/kg, and newer battery technologies such as NiMH and LiON are in the 80-135 wh/kg range. |
