RE: 50g battery warning
The '50 was designed with primary (non-rechargeable) cells in mind so it won't recharge its batteries when USB power is available. And good thing, too - the differences between nickel cadmium, nickel metal hydride, various lithium and other rechargeable cells combined with the potentially disastrous effects of trying to recharge primary cells would almost certainly guarantee many damaged calculators had they included charging.
Generic but good alkaline AAA cells are inexpensive and great for travel - a small set of spares takes little room and allows immediate replacement when needed. The USB option is good when working extended sessions at the desk. It's nice to have both options! |
