As I understand it, that's the main reason for avoiding rechargeables - nothing to do with causing damage. With an alkaline (where voltage degrades slowly), the 'low battery' warning will give you plenty time to do something about it. With a rechargeable (voltage drops off a cliff when it runs out), you might not even get a warning before it shuts off. As with most inconveniences in aviation, that's guaranteed to be at the least opportune moment!
