Re: [Help] Eating up car batteries

driving, mostly city, 15-20ms each way, 5 days a week.

This is your problem, with a standard alternator, your looking at best case about 200 watt hrs or about 20% put back in. This will lead to cronic undercharging and sulfation of the battery plates. If you can use a trickle charger to keep the battery fully charged

I drove 6 minutes to and from the train station for a decade, and my battery lasted just fine.

That really depends on the sizing of the charging system and a few other variables.

It may be his problem, but it's not possible to say until other possibilities are eliminated, or this one is confirmed in some way.
