A few times it's just went to sleep with no warning with anything up to 50% still showing on the meter. Then when i plug in the power cable it is showing 0%.

I bought this new 24months ago and it's a MacBookPro5,1. Intel Core 2 Duo 2.4 GHz

Condition says poor there, but I'm sure it was in good condition a month or two ago... it's deteriorated badly recently. I do calibrate the battery every couple of months.

It says it is 1755mAh at full capacity, that was 4600mAh when it was new.

There's an Apple store I could take it to in Glasgow, what we talking for a new one?

$129 for a new one retail or $99 for a service part (USD). Difference is a retail battery will have a full 1-year warranty, while the service part will only have a 90-day warranty. Apple warrants removable batteries for 1 year or 300 charge cycles, whichever comes first, and you're outside the window for both.
