• Used in RC vehicles, drones, and other battery-powered gadgets.

Below are the key technical details of the 6V 2400mAh NiMH Battery:

The 6V 2400mAh NiMH Battery typically comes with two terminals or leads for connection:

Ensure proper polarity when connecting the battery to avoid damage to the circuit or the battery.

1. Connection: Connect the positive terminal of the battery to the positive input of your circuit and the negative terminal to the ground. Use appropriate connectors or soldering techniques for secure connections.
2. Charging: Use a compatible NiMH battery charger with a charging voltage of 7.2V. Avoid overcharging by using a charger with automatic cutoff or a timer.
3. Discharging: Ensure the connected load does not exceed the maximum discharge rate of 4.8A to prevent overheating or damage.
4. Protection: Consider adding a fuse or a battery management system (BMS) to protect the battery from overcurrent, overcharging, or deep discharge.

• Polarity: Always double-check the polarity before connecting the battery to a circuit.
• Charging Safety: Use a charger specifically designed for NiMH batteries to prevent overcharging or overheating.
• Storage: Store the battery in a cool, dry place when not in use. Avoid exposing it to extreme temperatures or direct sunlight.
• Cycle Life: To maximize the battery's lifespan, avoid deep discharges and recharge it before it is completely drained.
• Disposal: Recycle the battery responsibly at an authorized recycling center when it reaches the end of its life.

The 6V 2400mAh NiMH Battery can be used to power an Arduino UNO via its VIN pin. Below is an example circuit and code:

1. Connect the positive terminal of the battery to the VIN pin of the Arduino UNO.
2. Connect the negative terminal of the battery to the GND pin of the Arduino UNO.

// Example code to blink an LED using Arduino UNO powered by a 6V NiMH battery

const int ledPin = 13; // Pin connected to the onboard LED

void setup() {
  pinMode(ledPin, OUTPUT); // Set the LED pin as an output
}

void loop() {
  digitalWrite(ledPin, HIGH); // Turn the LED on
  delay(1000);                // Wait for 1 second
  digitalWrite(ledPin, LOW);  // Turn the LED off
  delay(1000);                // Wait for 1 second
}

Note: Ensure the battery voltage does not drop below 5V under load, as the Arduino UNO requires a minimum input voltage of 5V to operate reliably.

1. Battery Not Charging:

   • Cause: Faulty charger or incorrect charging voltage.
   • Solution: Verify the charger is compatible with NiMH batteries and outputs 7.2V.

2. Short Battery Life:

   • Cause: Overcharging, deep discharges, or high discharge rates.
   • Solution: Use a charger with automatic cutoff and avoid discharging below 1V per cell (5V total for a 6V battery).

3. Battery Overheating:

   • Cause: Excessive discharge current or charging at a high current.
   • Solution: Ensure the load does not exceed 4.8A and charge at a current of 240mA to 1200mA.

4. Device Not Powering On:

   • Cause: Incorrect polarity or insufficient voltage.
   • Solution: Check the connections and ensure the battery is fully charged.

• Use a multimeter to measure the battery voltage and verify it is within the expected range.
• Inspect the terminals for corrosion or loose connections.
• If the battery is not holding a charge, it may have reached the end of its cycle life and require replacement.

By following these guidelines, you can ensure optimal performance and longevity of your 6V 2400mAh NiMH Battery from Tosiicop.
