But when the engine is running the batteries only job is to get charged. If you don't have enough juice with the engine running it's a bigger alternator you need.
Only time the battery should supply current is if you have something like a winch or a 12v hydraulic setup drawing big power for a short period otherwise the alternator needs to meet demand, especially from electronics
