Battery securing help (Page 3/3) theogre MAY 26, 04:11 AM quote Originally posted by pmbrunelle: Can any BCI group 75 battery be properly secured with the Fiero clamp setup? Or does one have to be careful in selecting among the available group 75 batteries for one with bottom lips of just the right size? All "real" Group 75 and related have correct bottom design to work in GM vehicles w/ this mounting setup. Most brands for North America are made by either Johnson Controls or Exide for Decades. So you have less problem buying a battery to fit any OE mounting. (JC was sold to Brookfield Business Partners LP just last year and Middletown DE Battery Plant is to close in 11/2020 after got violation notice from DNREC, state's "EPA", in 01/2020.) See my Cave, Battery Some batteries may come w/ "adapters" on the battery base to fit X group size but Do Not use the adapters on any car w/ base mounting. Those only work w/ fixed top mount setup that need correct height.
