Anyone up on battery chargers? I have an old charger that doesn't seem to work with the AGM battery in the Triumph. The Battery Tender Jr. does seem to work OK with it so I'm fine, but I want to get a new one. I'm looking at the Clore 4520, a 20/12/2 Amp charger that should work well with cars and bikes. PS We already have several Deltran Battery Tenders or BT Jr, I want something that can quickly charge an automotive or motorcycle battery.
