The lead antimony plates are strong but the antimony leads to self discharge. this is so slow that it allows the battery to stratify, and therefore it needs more cycling and more equalization. <br></span></div><div><br></div> <div style="font-family: arial,helvetica,sans-serif; font-size: 12pt;"> <div style="font-family: times new roman,new york,times,serif; font-size: 12pt;"> <div dir="ltr"> <font face="Arial" size="2"> <hr size="1"> <b><span style="font-weight: bold;">From:</span></b> Exeltech <exeltech@yahoo.com><br> <b><span style="font-weight: bold;">To:</span></b> RE-wrenches <re-wrenches@lists.re-wrenches.org> <br> <b><span style="font-weight: bold;">Sent:</span></b>

<div class="yiv708037492plainMail">I've heard that Lead-calcium batteries do not need Equalization, I
think because<br>the electrolyte does not contain sulfates so the lead

is correct ?<br><br>
