I am using Exide batteries in four motorcycles that I get from Rural King (it's a farm store). So far, great experience with these batteries, two of them are past the two year point. TSC also carries this brand around here, but their price is higher. Right now the recommended one for the XS650's is on sale for $35.00 USD, regular price is $40.00 USD. I do not baby these batteries or constantly tickle them with a charger, just top off with distilled water and charge them at the beginning of the season. I check the water/acid level only once again mid-season, anything different than that is the bikes fault.....not the batteries'.
