That’s not very clear. How easy is ”readily”? I replaced a few and found the biggest obstacle being the glue they use to keep them in place inside (they must sit in compartments larger than the battery since it changes size). But would it be enough to not have glue and instead Velcro there? Would still require plugging and unplugging tiny cables and screwing out 20 tiny screws. Or does ”readily” mean ”hatch”? Not so sure people want hatches…
