Warranty Details


How long will the battey last unused? If I were to just store it for use in an emergency what would I need to do to maximise the life of the battery?

The shelf life of RIVER is up to a year, but in good storage condition. In order to maximize the life span of the battery we still recommend you discharge RIVER to 30%, then charge to 85% every 3 month.
