Procedure
• The battery temperature must be at least +10 °C.
Risk of explosion due to open flame, fire and smoking.
• On non-maintenance-free batteries, the sealing plugs must be installed tightly.
• Provide sufficient ventilation.
• A highly flammable gas forms when batteries are charged. Never enter rooms where batteries are being charged carrying an open flame or while smoking.
• Follow the battery charger and battery manufacturer safety requirements.
Risk of explosion on discharged battery with visual indicator.
• If the visual indicator has no color or is light yellow, the battery may not be tested or charged. Jump starting must not be used! There is a risk of explosion during testing, charging or jump starting. The battery must be replaced.
Risk of damaging the battery and vehicle electronic components.

• Do not rapid charge batteries in vehicles with a battery monitoring control module (J367) or energy management control module (J644).
• Do not rapid-charge exhaustively discharged batteries.
• Rapid-charging of batteries should only be performed in exceptional circumstances (for example, jump starting) since rapid charging may cause damage.
• Battery must not be connected to vehicle electrical system when performing rapid charging. Disconnect the positive and negative cables from the terminals.
• The maximum charging voltage is 14.8 volt.
