That is not true. A battery charger that is putting out too high VOLTAGE can overcharge a battery, so some really cheap chargers with nothing but a transformer and rectifier in them can possibly overcharge. A properly designed charger will not overcharge one though.
Think of this: Your alternator is capable of putting out over 60 amps, a charger is nothing but a substitute for the charge current from an alternator.
If ou use a charger rated at 10 amps, that does not mean that it will force 10 amps through the battery. It only means that that is the MAXIMUM the charger can supply. The state of charge of the battery is what determines the current (amperage) that will be drawn from the charger. If you use a 10 amp charger on a depleted battery it will draw near 10 amps at first, but as the charge builds up the amperage will drop until it reaches a low current, determined by the voltage of the charger.
One can charge a motorcycle battery just as safely using a 100 amp service station charger as you can with a small trickle charger. In fact, the Odyssey may not charge at all with a cheap 1 amp charger.
This is just the same as the myth that you cannot jump start a motorcycle with a car. Total bunk. The motorcycle battery cannot tell where the 13.5-14 volts is coming from, be it it's own alternator, a car, truck, or charger of any type that is putting out the proper voltage. The source VOLTAGE is the determining factor. Current (amperage) is the result of the voltage versus the state of charge of the battery.
