> An excavator or a tractor deprecates far more slowly, and many private owners keep them for 20-30 years. There are still tractors and excavators from the 50's in regular use. > Battery-powered equipment will probably need new battery packs before that. It's a tiny 10kWh battery, $1000 - $2000. It looks like about 6 hours / cycle, so that's ~4000 of work time, longer if you don't mind reduced capacity. That's quite comparable to a diesel which needs an overhaul every ~10,000 hours.
