Hi. I need some help. I went out to the bike last week and had a flat battery. My own fault because hav,nt started the bike lately. I borrowed a battery charger, recharge it, started no problem. But now i need to buy a battery charger, but which one. I can find plenty but they list 3,5,6,8, or 12amp/hour charging rates. but what would be the best to get. My bikes a Suzuki burgman 200 K9. My hand book says charging rate is 0.9A x 5 to 10 hours, max rate is 9A x 0.5hour. Would appreciate any help. Thanks Ginnelli.
