Hi - I'm trying to revive a 1992 940 Turbo sedan which has been parked for one year. The battery is dead and won't take a charge, so I want to replace it, but I'm having trouble with its hold-down bracket. I've never replaced a Volvo battery before so I'm not sure how the bracket is supposed to work, but I assume it's stuck. The bracket has a metal rod with a loop on the end, so I assume I'm supposed to pull or lever it to release the battery, but it just flexes and the bracket stays put. What's the trick? Can someone help with a little advice? Thanks!
