Many laptops just use regular M.2 SSDs which are easy enough to replace. For me this is a requirement not just for repairs but also for the initial configuration - bundled storage options are usually too limited.
Batteries are harder because the race to reduce thickness and weight means that they are usually optimized for that rather than being some standard format you can find replacements for.
