In terms of a starter battery, the Battery temperature in its location, and the ability of the vehicles voltage regulator to return battery close to or to 100% state of charge, have more effect on battery longevity compared to whomever made it.
Lots of battery terminal corrosion issues are caused by overtorquing of the battery post clamps.
Automotive posts or threaded studs exiting the tops or sides of btteries, are secured Only within plastic but, admit it, how many of you torque the post clamp nuts as if you were applying torque to Metal?
How many have ever used a torque wrench and know how much 220 inch pounds actually is?
Odyssey's group 31, AGM says max of 220 inch pounds. That translates to 18.3 foot LBs.
Pretty easy to exceed that with a simple open ended wrench and compromise the plastic. really the moment the post clamp is tight engouh it cannot be rotated by hand it is tight enough, and how many reading here, torque it as if it is a spark plug??
The Stud/terminal corrosion Likely, can be blamed on overtightening, in a high percentage of cases where this is a complaint by the end user.
18.3 foot pounds Max, on one of thehighest qualuty AGM batteries available, which uses silicon bronze posts, not super soft Lead, like most flooded starting batteries.
Perhaps Battery manufacturers need to print maximum torque values On their stickers in bold letters. Or mold them into the casing near the terminals. It would seem it would reduce warranty returns, and perhaps prevent Internet rumors from destroying a Brand.
