FAQ

• Cross-compatibility 20V/12V? No, each battery only powers its own platform.
• How long does it take to charge? This varies depending on the WORKPRO charger; refer to its power rating.
• Can I use it in the rain? No; protect the tool and battery from moisture.
• Loss of capacity over time? Normal; limit full cycles and heat to preserve lifespan.
• Indicator suddenly goes out? The BMS has shut down to protect the battery; recharge before resuming.
• Transport in a vehicle? Secure the battery away from tools, away from shocks and heat sources.
