🔋 Understanding 25C Discharge Rate

The 25C discharge rate means this battery can safely deliver 25 times its capacity in current. For a 110mAh battery, this equals 2.75A maximum discharge current - more than sufficient for electric toothbrushes and small Bluetooth devices. This high discharge capability ensures:

• Consistent power output throughout the discharge cycle
• No voltage sag during high-demand moments
• Reliable performance in power-intensive applications
• Longer effective runtime compared to lower C-rated batteries
