<html><head><meta http-equiv="content-type" content="text/html; charset=utf-8"></head><body style="overflow-wrap: break-word; -webkit-nbsp-mode: space; line-break: after-white-space;">I have recently been installing lead carbon VRLA batteries and they have some nice characteristics over conventional AGM's such as rapid charge and \u2019allegedly\u2019 significantly reduced sulphation. I have generally avoided VRLA and recently had a client toast a $15k set of Rolls (sulphation) in a very short time due to incorrect charge settings. This is a Canadian distributor but similar batteries may be available in the U.S.<div><br></div><div><div style="display: block;"><div style="-webkit-user-select: all; -webkit-user-drag: element; display: inline-block;" class="apple-rich-link" draggable="true" role="link" data-url="https://hubpower.ca/wp-content/uploads/2024/01/HC6-420-Spec-Sheet.pdf"><a style="border-radius:10px;font-family:-apple-system, Helvetica, Arial, sans-serif;display:block;-webkit-user-select:none;width:228px;user-select:none;-webkit-user-modify:read-only;user-modify:read-only;overflow:hidden;text-decoration:none;" class="lp-rich-link" rel="nofollow" href="https://hubpower.ca/wp-content/uploads/2024/01/HC6-420-Spec-Sheet.pdf" dir="ltr" role="button" draggable="false" width="228"><table style="table-layout:fixed;border-collapse:collapse;width:228px;background-color:#E5E6E9;font-family:-apple-system, Helvetica, Arial, sans-serif;" class="lp-rich-link-emailBaseTable" cellpadding="0" cellspacing="0" border="0" width="228"><tbody><tr><td vertical-align="center" align="center"><img style="width:228px;filter:brightness(0.97);height:294px;" width="228" height="294" draggable="false" class="lp-rich-link-mediaImage" alt="preview.png" src="cid:413B2240-5380-4908-BDA1-172BFB0977A4"></td></tr><tr><td vertical-align="center"><table bgcolor="#E5E6E9" cellpadding="0" cellspacing="0" width="228" style="font-family:-apple-system, Helvetica, Arial, sans-serif;table-layout:fixed;background-color:rgba(229, 230, 233, 1);" class="lp-rich-link-captionBar"><tbody><tr><td style="padding:8px 0px 8px 0px;" class="lp-rich-link-captionBar-textStackItem"><div style="max-width:100%;margin:0px 16px 0px 16px;overflow:hidden;" class="lp-rich-link-captionBar-textStack"><div style="word-wrap:break-word;font-weight:500;font-size:12px;overflow:hidden;text-overflow:ellipsis;text-align:left;" class="lp-rich-link-captionBar-textStack-topCaption-leading"><a rel="nofollow" href="https://hubpower.ca/wp-content/uploads/2024/01/HC6-420-Spec-Sheet.pdf" style="text-decoration: none" draggable="false"><font color="#272727" style="color: rgba(0, 0, 0, 0.847059);">HC6-420-Spec-Sheet</font></a></div><div style="word-wrap:break-word;font-weight:400;font-size:11px;overflow:hidden;text-overflow:ellipsis;text-align:left;" class="lp-rich-link-captionBar-textStack-bottomCaption-leading"><a rel="nofollow" href="https://hubpower.ca/wp-content/uploads/2024/01/HC6-420-Spec-Sheet.pdf" style="text-decoration: none" draggable="false"><font color="#808080" style="color: rgba(0, 0, 0, 0.498039);">PDF Document · 378 KB</font></a></div></div></td></tr></tbody></table></td></tr></tbody></table></a></div></div></div><div><br></div><div>Ron</div><div><br><div><div><br><blockquote type="cite"><div>On Sep 23, 2024, at 3:36 PM, jay via RE-wrenches <re-wrenches@lists.re-wrenches.org> wrote:</div><br class="Apple-interchange-newline"><div><meta http-equiv="Content-Type" content="text/html; charset=utf-8"><div style="word-wrap: break-word; -webkit-nbsp-mode: space; line-break: after-white-space;">HI All,<div><br></div><div>You\u2019ve all obviously had people take way better care of their VRLA batteries than I have.
