Hi all, advice needed, purchased a 468w/hr battery from Allbatteries as an additional battery for my Haibike SduroTrekking Trekking with Yamaha PW motor. Bought it in January, but has had little use up to now, used it and drained it fully, recharged it again but caught dreaded flu bug, so was a gap in time til today when I switched it on, it showed full charge on battery indicator but the bike screen shows all the symbols as if it on test mode, then switched off. There is no drive to the motor. Put the original Haibike battery in and it works perfectly. Any ideas anyone, before I contact Allbatteries on Monday?
