I need to get a replacement battery for an old laptop I have. I have found a site with good prices, but I have a choice of two options.

SPECIFICATIONS: Type: Li-ion
Voltage: DC 10.8 V
Capacity: 4400 mAh
Color: Black
£39.90

or

SPECIFICATIONS: Type: Li-ion
Voltage: DC 10.8 V
Capacity: 8800 mAh
Color: Black
£59.90

what I don't understand is what the difference is between the 4400 and 8800 mAh batteries? I'm assuming the 8800 last longer when used? But I can't find any details. Another sites has the 8800 mAh listed as "Hi-Capacity". Do these batteries have generic times for home long they last? i.e 4400 2 hrs, 8800 4 hrs?

The second one should roughly last twice as long as the first one.

You can't really say how long as it depends what you are using the computer for, but whatever you are doing the second one will always last about twice as long.

Okay thanks, now just need to decide whether to pay the extra £20 for longer life battery (its a pretty old laptop) I know it varies depending on what you do (i.e using video as opposed to just using MS office, etc), but I wish these things gave some indication. Didn't most older laptops only have a 2-3 hr battery life or am I mistaken?

About 500 grams more and maybe an extra a inch and a half sticking out the back.

Just relate it to the size and longevity of your current battery.
The small one's capacity is 47.5 watt hours (Amps multiplied by Volts)

Okay and that means? I'm tried calling the company to see if they can give me estimated battery life (not lifetime, but how many hours it'll keep my laptop running without charging), but just get their automated voicemail system at the moment.

What laptop do you have? Make and model if possible.

Just look at your current battery and remember how much life you got when new.
A tiny bit of maths and thats your answer.

And far more exact than any guesswork from a 3rd party considering individual specification and operating system play a major factor.

Its a Compaq Presario V5234TU (V5000 series), according to Windows 7 (which I have running on it) it has a Celeron M, 410 1.46GHz processor and 768 MB ram.

As for the battery. The problem is I don't have a battery at the moment. Its an old laptop (approx 2004/05) that a friend hadn't got around to throwing away (it was a bit battered looking and wouldn't boot up) anyway, on the basis that it was getting binned, they sold the battery on ebay. I saw it one day and they were happy for me to have it. Turns out, although its a little battered it only needed reformatting and reinstalling windows. For the past few months I've used it, but always powered by the mains power supply. Getting sick of having to shut it down completely everytime I turn it off to move it (it even loses the time/date if its off longer than 4-5 hrs) hence, finally deciding to get a battery.

Well expect about 2.5 to 3 with the small one and 5 to 6 with the big one.

Personally I would plump for a big one at £40 direct from Hong Kong via ebay.

Genuine standard '5000 series' HP ones will be cheaper too there so you might just decide on that.
£60 is about half the value of the laptop.

Thanks, always a little weary of sellers from Hong Kong/China. Don't mind when its just a cheap lead or something but worry when were talking £40, etc. I'll have a look though.
