UPDATE: I added a 25mA discharge (which took forever) to really highlight where Alkaline starts to shine, under light loads like in a TV remote or smoke detector for example. Given, you can't recharge them when they finally do die, but still, light loads are their specialty.
My brother was in town over Thanksgiving and we got going on a conversation about batteries. After talking I realized although I have done post in the past about discharging different brands of batteries, It can be beneficial to just have a very simple comparison between battery chemistries
Below are the plots comparing Alkaline AA cells with rechargeable NiMh AA cells under 4 different loads. The voltage during discharge is plotted with the capacity in milliamp hours (mAh) on the bottom. All charts are the same scale for easy comparison.
