HP DV7 Laptop Battery recommendations

Hi all,
I have a DV7 Laptop and the battery has gone again.
Whether I buy HP branded or no name the battery only seems to last for 12-15 months - it's mostly connected to the power anyway.
Any good places to go or avoid, does it matter whether I spend £18 or £60?
Thanks in advance!

For example this page has the original spec 14.4v 5200mAh for £18 and another at 7200mAh for £28, 1 year guarantee:

and this one 14.8v 4800mAh and 3 year guarantee:

Just wondering if the mAh matters...and I guess I should be taking the battery out if plugged in to a socket?

To put things in a simple context, the mAH is the amount of charge it can hold, So the cheaper one has about 92% of the capacity of the more expensive one.
As for guarantees with batteries, you will generally find them not to be worth the paper their written on, due to batteries generally being classed as consumables, the guarantee usually only cover actual faults and not "It doesn't hold charge anymore" - Think of it like a guarantee with a printer ink cartridge, if you use all the ink, that's your problem, it worked.
Personally, Id buy the cheaper one, and with regards to being plugged in, yes, technically you should take the batter out when fully charged on and mains power to get the best lifespan, Id also recommend completely charging and completely draining the battery a couple of times a month as this also helps maintain lifespan.

Thank you Paul.
Right, got the mAh thing. Funnily enough I was draining/recharging regularly but I guess just over a year is all I can expect.
Which? have something to say about only using UK based retailers.
