Normal pedestrian Class A fires (like paper or wood)--yes. Which you can use water/CO2 on.

Or Class B/C (gasoline and electrical respectively)...which you use dry chemical or CO2.

But a battery fire is a metal fire. Metal fires are "Class D" Which is its own thing.You don't use water or CO2, you have to use dry powder extinguishers.

If at your workplace you see fire extinguishers on the wall (hopefully by Code you do)...that is what the "A/B/C" on the side means....you'll virtually never see a Class D or Class K equipment--as those tend to instantly be "call a professional" style emergencies.


Using the wrong equipment can make for massive disasters. The USS Forrestal had a massive fire in 1967 that nearly destroyed the carrier...made worse because emergency fire crews were spraying water at fuel oil fires--doing nothing more than spreading the burning fuel everywhere. Ofc, they were desperate--the professionals on ship were dead or injured, and the proper equipment was the first thing destroyed by ammo explosions.
