@SammysHP The reason I use Alkaline in some applications is I have some devices where voltage is important and they will not run on 1.35 NiMH voltage but they will run on 1.6 Alkaline voltage. But I agree, performance is bad. Unfortunately the 1.5v lithium ion cells aren’t really 1.5v, they’re 3.7 or so and regulated down. This causes two issues, the regular introduces a lot of RF noise, and the voltage is flat right up to the point of complete exhaustion so you can’t tell when the battery is ready to crap out.
@SammysHP Again, the devices in question actually use three cells (4.5v nominal) will tolerate 4.8 but not 4.05. So can’t substitute one cell for two in series. Could probably regulate down from a higher voltage but then you get the noise issues again.
