<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">I understand your point.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">What I clarified is that
</span><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">periodic cycling is<span class="apple-converted-space"> </span>not<span class="apple-converted-space"> </span>a requirement or benefit in achieving longer flooded lead acid
deep-cycle battery life. Equalization is still required depending application specific, yet at a much lower periodic rate than if the application was true cyclic.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">I also agree that there are lead acid batteries out there designed just for floating applications. Their design focus on thinner plates for higher current and
less cycling. This technology does focus on low self-discharge, high corrosion resistance, not on the various technologies specifics related to deep cycling. Hence they like floating applications that stays in float mode 99% of the time and need to crank
power very occasionally. Cycling such batteries will be reducing dramatically their life.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">In a nut shell: there are benefits to tap in both technologies. Certainly there are “UPS” applications where floating mode is not looking for deep-cycling.
Certainly there are “cyclic” applications where deep-cycling capability are mandatory. And then you have all in between, which makes all of us excited with different opinions. Ask 10 battery experts and the answers will be “it depends”. I would say, understanding
the loads and the application is a great step towards long life. Next steps are picking the right battery for the application, sizing, installation and maintenance.<o:p></o:p></span></p>
