2016 Forester Touring -Battery Drain

[KayakME]

I have 2016 Forester that has gone through 5 batteries in 3 years. Has had new starter, wiring harness and alternator checked good. Two local Subaru dealerships have run the service bulletin I got for the Starlink module drain and they say it doesn’t meet the requirements for replacement, only drawing 40.3 not the 70 required. We pulled the fuse which seems to fix it but can’t go without that as it controls radio too and we are try to sell now. If it sits for 3 days or more battery is dead. I am at a loss of what to do next. Don’t want to sell as someone did to us. Any suggestions as to what else it could be. I still believe it’s the module with the bulletin but. No one will fix it. Frustrating as we have owned Subarus for many years.

As a last gasp you could install a tender charger and plug it in when you park for long periods. A tender charger is just a low Amp output battery charger that keeps the battery topped up. I installed one in my tractor, plugged in my rock crawler and both of my backup generators have them. Be sure to get one that's designed for the type of battery thats in your car. Regular flooded cell lead acid batteries and AGMs are a bit different.
