How long will the battery keep charged on the shelf, or in an occasional use car?

• conjecTech 11y ago
  On a shelf: upwards of 6 months. In a car: around a month if it's powering all the electronics. We also intend to have a switch that can electrically disconnect the battery. It would stop powering everything, but it would also allow you to store it in the car for the same 6+ months, switch it back on, and still start the engine.

    Oh, please do! Some of my cars will sit for a month and then the battery is dead due to parasitic drain. It's a pain to plan ahead and use tools to disconnect the posts.
