Purchased new in November 2016. Total operating time is only about 32 hours. It was operated for over an hour in September 2025, so I believe the battery is in good condition. The exterior appears to be in good condition with no damage or noticeable stains. I have cleaned it briefly, but please understand that I haven't cleaned every small detail.
