One of the most user-hostile companies on earth. My John Deere lawnmower came with a fuel gauge that runs off a CR2032 that's embedded in epoxy. The battery runs out of charge in about six months and the gauge stops working. If you saw the gauge open and replace the battery it doesn't start working again. If you disconnect the gauge the lawnmower won't start. Replacement gauges are $60.

Don’t buy their stuff then.
