October 17, 20196 yr I have a tendency to over-tighten bolts and nuts: When torquing-down the M8 bolts on 4 x Ritar 100AH VRLA batteries, I tried my best to take it easy, but noticed a small rotational-shift when tightening one of the terminal bolts. Does this mean I may have damaged the seal? How tight do you guys make your terminal bolts? Does anyone apply grease to the terminals? PS. The spec. sheet has a figure of 10 n.m - but I don't have a torque wrench with that low a setting.
October 17, 20196 yr You get terminal spray, like Q30 which you can spray on to prevent oxidation. I have seen people re-tapping the threads if they have stripped them. There is usually space to drill another hole and tap on the lead terminal.
October 17, 20196 yr Author These insert-type terminals are not lead - something a lot harder, so I'm not concerned about stripping the thread, more worried of the fact that the entire terminal rotated in the casing.
