Toyota Corolla Battery keeps failing, need a new one... How much are they...

[ttMadtttt]

...normally... UK... Plz help!? I have a toyota corolla solaire, 1300cc, petrol.
I know nothing about cars.
My battery keeps failing about 5 times aday and i have to keep using the charger. I think its about time for a new one.
Ive never personally taken my car to a garage before and have to now. How much does a battery normally cost. I thought i'd do my research first.

Thanks

Is the alternator charging the battery correctly? Maybe you need to tighten or change the belt? Don't just assume it to be the battery, which will rapidly flatten if it is not charged correctly!

$50-$150 not sure what that is in UK money.
