    If i get a replacement battery for my mid-2009 mbp 15" will it be better, longer lasting, than the original one or will it be exactly the same? ie. will it be old tech battery or new tech battery?

    I appreciate how long the battery lasts is, to a large extent, a combination of battery size + tech + mbp component efficiency.

    Mid-2009 battery was meant to last 6-7 hours i think whereas the current mbps battery life is 8-9 hours.

    What do you think?

    Im at 423 cycles / 96% health on my current battery after 1 year of usage so it prob wont be until mid next year before i notice a drop in performance.... thought id ask for opinion now anyway.
