These might seem like odd questions but just bare with me. 8)
It depends on the type of battery charger I guess but basically I can't see a problem with that. The voltage at the bulb will be a bit higher than just the battery on its own, but as you say no different to what the light gets on a car or motor bike. If you use a fancy battery charger that monitors the state of the battery I'm thinking it will indicate a duff battery. This is because the bulb will be drawing current and making it seem like the battery is discharging itself.
