Macbook Pro replacement battery help, for the completely technically useless...

[Noise annoys]

Hi!
Completely stupid question here, I am sure, but I'm completely unable to work this out, so I'd really appreciate some help.
I'm trying to get a replacement battery for my macbook pro 7.1, 13". I think its from 2010 but I'm really not sure. I bought it in the UK. I already ordered the wrong model once (duh) so I don't want to do that again. Where can I find out which battery to get? Please help!
Thanks in advance!

Amazon is my go-to. The vendors might be different in the UK or not, but I'd bet they carry something like this below. Without knowing how you ordered the wrong battery, can't say how to avoid that. They go by model number and have a compatibility list usually, so hard to mis-order.

Apple's part number for the correct battery is 661-5557
That might help to determine if the part is correct.

iFixit, as usual, is a good place to look - https://www.ifixit.com/Guide/MacBook+Pro+13-Inch+Unibody+Mid+2010+Battery+Replacement/4300
