If you don't like it, buy (heavy!) batteries using a different chemistry.

If that's based on what "some bloke in the pub told me", I strongly
counsel you to check if it applies to the chemistry you're using.
This is not my field, but I know that best practices are not portable
between e.g. NiMH and Li chemistries.
I run two Panasonic toughbooks both with lithium cell packs, it has a mode in the BIOS that restricts charging to 80% to prolong battery life when permanently connected to an external PSU as might happen when mounted to the dash of a police car or ambulance so if that practice is no good for lithium tech then why would a manufacturer implement it on their hardware ?
