Using water on an electric fire sounds like a dumb idea to me. But yeah, the MSDS does seem to say that...
A venting lithium ion battery isn't usually an electrical fire.

And what of all the molten wires that _were_ charging said battery?
Overcharging a battery isn't the only way to cause it to vent :)
Obviously there should be a physically separate circuit for cutting off power in the event of catastrophe. That's pretty much rule-of-thumb for large li-ion battery banks.
According to the MSDS for lithium ion batteries, fires involving them can be extinguished with a typical ABC fire extinguisher.
Lithium batteries (not the rechargeable kind) are the ones that need a class D extinguisher.
Edit:
> CO extinguishers, halon or copious quantities of water or water-based foam can be used to cool down burning Li- ion cells and batteries. Do not use for this purpose sand, dry powder or soda ash, graphite powder or fire blankets.
> Extinguishing media Use water or CO2 on burning Li-ion cells or batteries
