Yep, Yuasa is pretty common. If it's an AGM (as it should be), there are still specific charging requirements to get best outcomes. Lots of folks have run their Odysseys on common chargers, but I have certainly seen better performance with a correct charger. It can be done manually with any charger 6 amps or more and a careful eye on the voltmeter.
My last PC545 (2014) came from Amazon, $99.84 +about ten bucks sales tax.
