How long the battery lasts depends on which kind you got. The average lifespan of such a battery is two years.
Yes, it mAh or Ah is how long the battery lasts, it does not affect performance.
The 6 cell battery lasts about 2 to 4 hours, the 6 cell is a little smaller and a little cheaper. The 9 cell battery is a little larger, costs a little more, and lasts a little longer.
My cellphone battery
I think the walkman battery lasts about 12 hours when fully charged.
the battery life depends on how high or low the light is. when it is on minimum brightness, the battery lasts 13-17 hours. when it is on maximum brightness, it lasts 4-5 hours. it also depends on how long you charge it. hope this helps!
