They also have a calendar life. It is generally accepted that LIFE batteries have 5000 deep cycles and 10,000 equivalent cycles if they are shallow, slow discharge and slow charge. In a LA battery the discharge state is about 1.8 x thicking of the plate. The LIFE plates thicken about 4%? so they do have a mechanically determined cycle life. AGM pure lead plates in Outback and Kilovault have a cycle life of 3000 equivalent cycles if the cycles are shallow. (meaning 50% DOD, 6000 times) The NCO type high energy density batteries have a shorter cycle life of about 1500 cycles, however Jeff Dahm has additives in Some Tesla batteries that extend this, however, you can not buy these batteries and why would you want to unless you are doing an electric car? </div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Mon, Aug 24, 2020 at 5:52 PM jay <<a href="mailto:jay.peltz@gmail.com">jay.peltz@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><br>
Dear lithium experts<br>
<br>
Do lithium LFP or NMC batteries have a break in period ( a certain number of cycles or any other specific parameters) to have full capacity?<br>
<br>
Thx<br>
