Finding the Right Security Alarm Battery

The type of replacement battery you need will depend upon the size of your security panel and the type of equipment that's installed. Learn more about the different types of batteries and their properties to help you decide which option is best for your system:

  • Conventional Lead Acid - Lead acid batteries are a safe, reliable choice for most home security systems. While they can withstand a certain degree of temperature flux, they tend to lose their charge more quickly in extreme temperatures, so they're best suited for indoor panels and appliances.
  • Rechargeable Batteries - Some wireless all-in-one systems use a rechargeable battery rather than a sealed lead acid. These systems likely specify whether rechargeable batteries are safe to use. Avoid using
    rechargeable designs unless the model specifically says it's safe, as not all security systems feature rechargeable capacity.
  • Lithium Batteries - Lithium batteries are designed for durability in very cold conditions, offering a popular option for outdoor devices. They also have a long shelf life, which makes them trustworthy for backup power.

Check your home security system instructions for which batteries are safe to use in your device. If you're still not sure which replacement battery is right for you, visit your local Batteries Plus store and our experts can help you find a reliable choice.
