Hi I am interest in purchasing Lenovo - IdeaPad Model: P500 – 59347559 laptop.
I notice reading the tech specification, the laptop has a 4 lithium battery permanently installed.
From reading a review of this model on Google, a user stated he was getting only 2.5 hours of battery time before recharging.
Can someone explain what should be the normal average time of this battery before recharging?
Also 4 lithium seems rather small size compared to other brands(HP, Dell) having a 6 to 8 cell lithium.
Is 4 lithium that max size that can be use for this model? If no, can I upgrade it on my purchase?

From my experience, a 6 cell lithium battery can give you 2-4 hrs and a 4-cell lithium battery will give you 2-3 hrs.(depends on usage).
For the battery life, OEM's usually do a battery lifespan test from a 100% charge until the battery drains out. What they do is set the computer to idle & maximum power saving (setting power options to power saver, lower the brightness, etc.) then the recorded minutes from the test would be the maximum battery life. As for the usage, if you play videos, games, music non-stop then getting 1-2hrs battery life is normal. For moderate surfing and spreadsheet documents, you should get up to 2-3 hrs.
As for upgrading the battery, 4 cell is already the maximum capacity as this battery is a special design for this model (see page 40 of the hardware maintenance manual on how to replace the battery).. For charging, you can safely charge the battery when it goes down to 15 percent or less (about 2-3hrs of usage). To maximize the full potential of the battery, it must undergo 3 cycles (drain the battery then charge it back to 100%).

Hope this helps.
