Doing this twice or three times will help remove the sulphation. let the battery cool between charge and discharge cycle. <br /><br />B https://www.blogger.com/profile/10586046436233366155noreply@blogger.comtag:blogger.com,1999:blog-2807403883562053852.post-24442329513421734472021-08-28T10:47:16.309-06:002021-08-28T10:47:16.309-06:00Read the following article.

To get them on the wires to the female cigarette lighter socket involved crushing the clamps on the female connectors."<br /><br />Those are commonly called spade terminals and are common as dirt. You should get a wiring crimper tool (special pliers) to strip the wires and make the crimp connections to the wires.Jeffhttps://www.blogger.com/profile/07576197256589251065noreply@blogger.com
