Opening a Laptop Battery for replacement

[Ella]

Hi All,

I am looking to replace a rather tired lappy battery. From 2.5 hrs it is now down to 1.25 hrs and most of the time I cannot rely on it for any time that matters.

I can get a replacement for £80 to £100 but this seems an awful lot of money for a two year old lappy. I see that some sites want up to £160? That's over ten per cent of what the computer cost and over fifty per cent of what it's worth now!

If I open the casing, can I match and replace the actual cells at lesser expense. If so where do I go for the replacements.

I suspect that the battery is a Fujitsu Seimans model. The only references on it are as follows;

BTP-44A3
Model; MS2111
Part No 49.0010.001.001.010
LI-ION 14.8v 5880mAh.

Thanks for any help available.
