Recommend somewhere to buy laptop battery-should I fit?

So it looks like the battery in my Fujitsu Siemans Amilo L6825 has died.

Their website isn't much use.

I've checked the usual suspects

Elara
Marx
Komplett
Peats

(No joy)

as well as www.computerbatteries.co.uk (anyone heard of these?)
Haven't got access to Ebay.

Is there anywhere around Dublin where I could buy such a battery?

Secondly-it seems fairly straightforward to replace-one thing to watch is for electrical shock-should I do it myself?

CCOVICH, I found one on eBay — from what looks like a reputable seller — for Stg£45.99 plus £12.99 courier delivery to Ireland (=+€88?). [broken link removed] the link, in case you can access it elsewhere later, and a clickable thumbnail, if not. 2-4 days for delivery, according to the seller.

If you like — seeing as we 'know' each other! — I'd be happy to order it for you and you could fix me up later. Pm me a delivery address, if so.

Thanks Dr. M-your offer and work much appreciated.

The price compares very favourably with what I found on www.computerbatteries.co.uk

Shucks! Let's just call it the 'Friday feeling'...

As long as you let me call 'round and watch you fitting it?
