Is it possible to upgrade a macbook pro 15 late 2008 memory upgrade to 8 go

Question

Hi from Belgium,
Is it possible to upgrade a macbook pro 15 late 2008 memory from 4 to 8 go. And if yes would i have to replace both memory modules.
I'm also experiencing problems with the battery. Could you tell me if the new replacement batteries are based on the new techonology (long lasting) or if the replacement battery will be the same as the original one.
Thanks and have a good day.

Hi CMCSK and thanks.
Maybe it's because of the SMC reset I've done.
My computer wasn't responding to the power button when pressed and used to shut down unexpectedly so I did the SMC reset as per the procedure hereafter.

So according to you, the battery seems to work properly and doesn't need to be replaced.
Don't know if it's important but the figures I gave where the one with magsafe connected.
In fact for the time beeing I only use my computer with magsafe plugged.
I just unplugged the magpower and here are the new figures after 10 minutes.
Charge Information:
  Charge Remaining (mAh):          3103
  Fully Charged:          No
  Charging:          No
  Full Charge Capacity (mAh):          3491
  Health Information:
  Cycle Count:          245
  Condition:          Normal
  Battery Installed:          Yes
  Amperage (mA):          -1431
  Voltage (mV):          11816
Are these figures still ok ? Thanks for your help and have a good day.
