That’s… a lot of cycles. That’s almost a decade. Plenty of time to build an electric generator from scratch by traveling on foot to a copper mine and smelting the wire yourself. Unless you manage to pull an alternator from a car that can’t find gasoline and save yourself the trip. From that you could make a gravity battery or any number of other options.

Point being, after 3000 cycles, it’s toast and there’s no fresh bread available.
Yes, you could construct something, but I think you’d be pretty amazed at how maintenance intensive a 1kWh gravity battery is.

Point is that 3000 cycles is more than enough time to find or make a replacement even if society doesn’t rebuild.

If you’re living somewhere with enough easy food, water and shelter that you’re not spending all your time just handling that. Making groceries takes a lot of time and effort.
