Each battery is 35 Wh, so that&#8217;s 0.14 kWh total. The two battery electrodes are actually zinc (Zn) and nickel oxyhydroxide (NiOOH), giving the cell a nominal potential of about 1.8 V. The benefit of these batteries is that they last a long time, being able to cycle at 100% capacity more than 3000 times. There are a few tricks to doing this. One is to have the electrolyte flowing, which is why we call it a &#8220;flow-assist&#8221; battery.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>I&#8217;m getting a new website started, quietly posting things until I point my URL to it.
