IbizaPartyBoy 34 Posted January 27, 2016 Report Share Posted January 27, 2016 Ive had mine years.. got red, yellow and blue.. all go flat.Usually leave them hooked up as auxilary power in boot of car for a few days and they take a charge and come back to life. boab3 1 Link to post Share on other sites
