- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/AA0289:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)

Note 1: This charger may not fit all 20700 and 21700 cells (which are by definition 70.0 mm long). If the the manufacturer has added protection circuitry to the end of a 700 size cell, this often changes the physical size of the casing by a few millimetres. As a result not all "700" size lithium cells will fit.
