> Newer appliances have solved these problems. For example, the Yamaha PSS-A50 (a fantastic, inexpensive portable keyboard) has an option to configure the low-battery indicator for alkaline or NiMH chemistry. Different NiMH chemistries have slightly different voltage curves. Its an insidious problem. Different brands of NiMH just discharges in a "flat" manner, and all of them are at slightly different voltages. The electronics assume a voltage curve of Eneloop (typically, since Eneloop is the most popular NiMH brand), and other brands with their slightly different voltage-curves will throw it off. ----------- I find it more important to locally source NiMH batteries (ie: what I can buy from Walmart / Home Depo down the street, rather than paying for Amazon shipping) rather than standardizing upon the Eneloops that everyone else is buying, lol. When I need a new AA cell, I buy it in my typical shopping runs, rather than waiting for shipping. I don't care enough about the voltage-curve problem to mass buy Eneloops yet. I largely just accept that the "low-battery" indicators are perpetually wrong.
