Lithium Ion batteries do not contain any lithium metal. They are considered Class B fires. Do not use a Class D extinguisher on them. Water is an acceptable way to extinguish a Li-Ion battery. Most battery factories use water to extinguish Lithium Ion battery fires. Lithium-METAL batteries on the other hand require a Class D extinguisher. They are not Lithium Ion batteries. They are single use devices and can NOT safely be recharged.
