anyone you note that you decide to help?
I'm retired Telco "central office technician". among other duties, did eons (seemed like that long, anyway) of servicing of lead/acid batteries in-house. keep electrolyte at proper level, terminals clean, keep connectors clean, apply some sort of "non-insulating grease" (Telco in Ohio preferred "No-Ox-Id"). used same protocol for personal vehicles. It worked, for me. in 40+ years I have had one vehicle battery die on me. 4yr old car bought new, a Ford Focus with the battery stuffed under the edge of the hood/firewall. no way to access the back 3 cells without 1/2 hr or better dissection. Waited until one day wife said "car won't start". I took the old one out (happened to be sitting in the garage, she had run an errand earlier, no problems) and bought a new one. I do keep a good set of jumper cables. have used them lots of times for others. Hope that helps
