There is no difference, the term is the same everywhere. You aren't using a full cycle every time you recharge your battery.

Here is another link.

"You don't need your 100% discharge and 100% recharge equivalent cycle theory to come to that conclusion. "

If you accept the idea that a discharge to 80% DOD only uses .8 cycles, then I guess we...

"Explain how these 100% discharge and 100% recharge equivalent cycles can be used if it is a meaningful measure of battery life."

I already did. If you look at how many KW you will get over the...

"We are talking about Lifelines definition, their chart, there specs,"

But apparently not their conclusion that it makes a "dramatic" difference in battery life?

"In APPENDIX A, they define a cycle as one sequence of discharge and charge. This seems contradictory, no? "

Not to me. I think if cycle meant how many times you can charge your battery it would...

I have not seen any reference that treats a cycle as a anything other than a fixed depth of discharge, usually 100%. Cycle life however is not fixed, as the chart shows. At an average depth of...
