Higher temp for shorter time is better than lower temp for longer time.
Especially for desoldering, especially if desoldering with wick instead of vacuum, crank it up and then get in & get out.

I'm replying to this question on-list since it seems relevant. I use an 80 watt desoldering vacuum gun (one of the common "ZD" types) set to about 325C for just about all of my lead-based desoldering work. I'll occasionally have to go up to ~350 or 360 but that's pretty rare. As others have commented, you can also snip the battery legs to remove some of the thermal mass and make desoldering easier -- but I would make sure you have small, pointy cutters for that to avoid damaging the board with the cutters themselves.-Josh at what temperature do you prefer to hit those big solder joints on the battery? I'd like to minimize the potential for board damage.
