How to Use XL-10AH: Examples, Pinouts, and Specs

The XL-10AH is a lead-acid battery designed for reliable power storage and delivery. It is commonly used in applications requiring a stable and consistent voltage supply. With its robust design and dependable performance, the XL-10AH is ideal for use in uninterruptible power supplies (UPS), emergency lighting systems, solar energy storage, and small-scale electric vehicles. Its versatility and durability make it a popular choice for both industrial and consumer applications.

The following table outlines the key technical specifications of the XL-10AH battery:

The XL-10AH battery features two terminals for electrical connections. The table below describes the terminal configuration:

1. Determine the Load Requirements: Ensure the connected load does not exceed the battery's maximum discharge current of 10A.
2. Connect the Terminals:
   • Attach the positive terminal of the battery to the positive input of your circuit.
   • Attach the negative terminal of the battery to the negative input of your circuit.
3. Charging the Battery:
   • Use a compatible lead-acid battery charger with a charging voltage of 13.5V to 13.8V.
   • Avoid overcharging by monitoring the float voltage (13.5V) during long-term charging.
4. Safety Precautions:
   • Always connect the battery in the correct polarity to prevent damage to the circuit or battery.
   • Avoid short-circuiting the terminals, as this can cause overheating or damage.

• Ventilation: Ensure proper ventilation around the battery to prevent the buildup of gases during charging.
• Temperature: Operate the battery within the specified temperature range (-20°C to 50°C) to maintain performance and longevity.
• Storage: Store the battery in a cool, dry place when not in use. Recharge the battery every 3-6 months to prevent self-discharge.
• Disposal: Dispose of the battery responsibly at a certified recycling facility to comply with environmental regulations.

The XL-10AH can be used to power an Arduino UNO in portable applications. Below is an example circuit and code to read a sensor value while powered by the XL-10AH:

1. Connect the positive terminal of the XL-10AH to the VIN pin of the Arduino UNO.
2. Connect the negative terminal of the XL-10AH to the GND pin of the Arduino UNO.
3. Attach a sensor (e.g., a temperature sensor) to the Arduino as per the sensor's datasheet.

// Example code to read a temperature sensor value using Arduino UNO
// Ensure the XL-10AH battery is properly connected to the Arduino VIN and GND pins

const int sensorPin = A0; // Analog pin connected to the sensor
float voltage;            // Variable to store the sensor voltage
float temperature;        // Variable to store the calculated temperature

void setup() {
  Serial.begin(9600); // Initialize serial communication at 9600 baud
}

void loop() {
  int sensorValue = analogRead(sensorPin); // Read the sensor value
  voltage = sensorValue * (5.0 / 1023.0);  // Convert to voltage (5V reference)
  
  // Example conversion: Assuming 10mV per degree Celsius
  temperature = voltage * 100.0; // Convert voltage to temperature
  
  // Print the temperature to the Serial Monitor
  Serial.print("Temperature: ");
  Serial.print(temperature);
  Serial.println(" °C");
  
  delay(1000); // Wait for 1 second before the next reading
}

1. Battery Not Charging:

   • Cause: Incorrect charger or damaged battery.
   • Solution: Verify the charger output voltage (13.5V - 13.8V) and check the battery terminals for corrosion or damage.

2. Battery Drains Quickly:

   • Cause: Excessive load or aging battery.
   • Solution: Ensure the load does not exceed the battery's capacity. Replace the battery if it has reached the end of its lifespan.

3. Overheating During Use:

   • Cause: High discharge current or poor ventilation.
   • Solution: Reduce the load or improve ventilation around the battery.

4. Arduino Not Powering On:

   • Cause: Incorrect wiring or insufficient voltage.
   • Solution: Check the connections to the VIN and GND pins. Ensure the battery is fully charged.

Q: Can the XL-10AH be used in series or parallel configurations?
A: Yes, the XL-10AH can be connected in series to increase voltage or in parallel to increase capacity. Ensure all batteries are of the same type and charge level before connecting.

Q: How long does the XL-10AH battery last?
A: The lifespan depends on usage and maintenance. Typically, it lasts 3-5 years with proper care.

Q: Is the XL-10AH safe for indoor use?
A: Yes, but ensure proper ventilation to prevent gas buildup during charging.

Q: Can I use a solar panel to charge the XL-10AH?
A: Yes, as long as the solar charge controller regulates the voltage to 13.5V - 13.8V.
