Discharge
CAUTION: The battery contains nitrogen gas under high pressure even after the brake fluid pressure has been released. Do not puncture the battery or allow it to become hot. Do not attempt to disassemble it. Failure to observe safety precautions may cause the battery to explode.
1. After removing, secure the battery neck in a vice; the drain plug must be positioned exactly at the top.
2. Wear safety glasses or other face and eye protection. The escaping gas, although non-toxic, may carry dust and other solid particles.
3. Slowly unscrew the plug 3 and a half turns; wait 3 minutes until all the gas has escaped.
Nitrogen is an inert, non-flammable, non-toxic gas. There is no danger in its release into the atmosphere.
4. Slowly unscrew the plug completely.
