I have a 2017 P500 and I could not go more than 3 days before it wont start, dead battery. I put a disconnect switch on the module for my remote winch and now I get 6 days before the battery is dead. No other battery drain found other than the factory computer. I have a few questions; 1. There are very few battery choices available, any specific recommendations? 2. The battery housing looks like there is a bit of extra room beside it if I cut out a plastic support in the battery box. Does anyone have experience putting a larger capacity battery in the factory battery box? 3. The Honda dealer says it is normal to replace the battery every 3-4 years. Is this true?
Thanks
