Had a £90 battery with a 5 year warranty after it was bought mate :( I thought it was the battery too. I even took the battery back and swapped it for another just to make sure. Then had it all tested. battery was fine as you would guess just wasn't getting full charge when running then would be flat unless I have the side light's on. but doesn't get driven far either the Bugeyes my main baby. I just banged them led strips around the side of the lights so look's like daytime running lights with aftermarket headlights also with led's on look's pretty cool I think :D It's never bothered me to look into it once I figured out just keeping the side lights on worked
