laptop ddr3 8gb
does installing ram on laptop reduces its battery life?

I am having one dell inspiron n5010 model and my laptop specifications are as follows-
i3 processor
320gb hard disk
3gb ram ddr3 upgradable to 8gb
and i want to know that if i install 4g(2×2) ram more then will it reduce my laptop’s battery backup and does it can create any problem because i am buying used memory from my one friend who is selling me memory by removing ffrom is acer laptop which also have ddr3 ram

but my most important question is does it will reduce my battery life..
please answer fast because if i will not pay him today then he will sell memory to someone else..

It does not effect the life expectamcy of your battery at all. OK
