I imagine it depends on the type of battery and the usage, but if you have a battery meter you could measure it. Use the house bank for a day, measure the voltage, run the engine for an hour, measure it again. Looks like the number you want to get to is probably 12.8 V: https://naturesgenerator.com/blogs/news/lead-acid-battery-voltage-chart
I love blackberries. Once they're establish is almost a guaranteed harvest if you can beat the birds. Enjoy!
I still scream the aiiiieeeiioooiii song when I need to get someone's attention. Sometimes they think I'm having a stroke.
