Sealed battery designs shorten instrument life without disclosure
Around 44% of controllers ship with no user-replaceable power source, and the rechargeable cell inside is rated near 500 charging cycles while the pump, motor and housing comfortably outlast it several times over. The device therefore fails on a component nobody compares during purchasing, since specification sheets emphasise weight, speed and ergonomics instead. Commercially this converts a ten-year instrument into a three-year one and shifts a laboratory's cost of ownership substantially, which purchasing departments discover on the second replacement rather than the first. Specification sheets never mention it at all.
