flat battery

I have gone to the car this morning and it looks like the battery capacity has become insufficient to start the car. Bought the Varta E44 just over four years ago and it has been great up until today. Has anyone had any experiences getting a refund/replacement battery within the warranty period...

Hi, ***TLDR*** Is a battery condition reading via the charging post under the bonnet reliable? All I know is it's a Yuasa machine the guy used. ***TLDR*** I've recently had a breakdown where the car struggled to turn over, it had been progressively getting worse and I gambled that one time too...
