Battery replacement

[1.6mk4GOLF16v]

cars on a 51 plate and still got the original factory batery in it

while the cars at stand stil if i press the electric windows button everything dims for a second, never noticed it before so not sure if it should be like that

had a look in halfords and they recomended a battery that was £100, looked on ebay and its a diff battery for half the price
heres a link to them both:

Mine does the same mate when at a stand still if i push the electric window button the headlights dim quickly and also miine does it when not idling properly (probably the case of a throttle body clean with that issue) ill get round to it at some point lol

Changed mine today....not impressed went to euro car parts. Quoted $30 something on the phone got there and they charged me just shy of $80. I needed it though so bought it. Battery is  a bosh silver.
