1997 Buick LeSabre with a 5½ year old Delco battery. The battery works fine, but I assume it's near the end of it's useful lifespan. When I disconnect the battery to replace, will I loose computer or other settings? If so, should I run a jumper cable to another battery to temporarily maintain current? Thanks, JT

Hi, never had to worry about anything but radio presets but what you suggest sounds like it would work.If you put cables on the clamps, other end on battery posts then bolt clamps on new battery you shouldn't lose power to system and not lose any settings. Interested to see if this works, if you try this let us know how it comes out, might save a lot of headaches resetting stuff. Seems like a good idea! :idea: :P

Suggested Repair

Radio presets are the main settings typically lost when the battery is disconnected. To keep power during the swap, connect jumper cables from a spare battery to the cable clamps, then transfer the clamps to the new battery before removing the jumper.

Conversation Summary

The owner of a 1997 Buick LeSabre plans to replace a 5.5-year-old Delco battery that still works and asks whether disconnecting it will erase computer or other settings, and whether a temporary jumper battery would prevent that. The expert says radio presets are the usual concern and agrees the jumper method should maintain power and settings if the cables stay connected while the clamps are moved to the new battery.
