The voltage dropoff is pretty steep so you may not get a low battery warning in a timely manner. I lost a 48GX when this happened, so the usual rule of removing batteries when not in daily use applies.

Did the drained eneloops destroy the 48GX or just wipe your stored items?

Not entirely sure about the damage. The screen briefly shows some pixels when ON is pressed, then no longer responds until the batteries are removed and the contacts shorted. I would guess (hope!) damage to the power supply somewhere, but have had no time to investigate. Everything is SMT anyway, except for a couple of discrete capacitors...

Relying on another 48GX that requires pressing beneath the display to get the ON key working
