The "battery" light means the generator has stopped charging the battery. You can run the engine on the battery, but it will only last about a half hour if you do not use the lights, heater fan, and wipers.
It is possible your new generator has a problem, but there can be wiring problems related to it also that stop it from working. The place to start is by having the charging system tested, but if the warning light continues to be intermittent, that testing has to be done while the light is on, meaning while the problem is occurring, to be valid.
