Wow - I have never got anything like 7 years out of any battery. My FZ1 came with a cheap "Powerline" battery and to be honest it seems better than the Yuasa I normally buy. My track bike has a Shido Lithium battery and it keeps its charge almost indefinitely without any recharging. It is supposed to be charged with a Lithium specific charger but as long an old fashioned plain DC charger will work fine too. Just not a modified waveform type charger that uses pulses or sawteeth and such like as these damage the battery.
