DIY hybrid battery replacement

[Pan Galact Gargle Blaster]

Has anyone done a DIY hybrid battery replacement on a LS600hL?  I have just ordered a reconditioned battery that is due next week, and was hoping I wasn't going to be trail blazing on this.  Unless I find someone else's guide, I will plan to document my process to serve as a cautionary tale to the rest.

I hope you follow all recommended safety precautions and that you go by the factory service manual. Good luck.

I plan to do it while wearing tin foil mittens ankle deep in salt water.
