What battery does a home alarm system need? A simple guide

When the battery of your home alarm system runs out, choosing the wrong one can cause false alarms, malfunctions, or damage to the system.
Let's see how to choose the right battery, without errors.

🔋 What type of battery does an alarm system use?

Most home alarm systems use sealed rechargeable batteries, usually:

• 12V

• AGM or lead technology

• capacity between 1.2Ah and 7Ah

❌ Car batteries are NOT suitable
❌ Lithium batteries are not compatible unless specified by the manufacturer

⚡ AGM or lead: which to choose?

• AGM → more reliable, longer life, less maintenance

• Traditional lead → cheaper, shorter lifespan

👉 For a home alarm system, we always recommend AGM, especially if it operates 24/7.

📏 Pay attention to dimensions

Even if Volts and Ah are correct, the dimensions must match the alarm system's compartment.

Check:

• length

• width

• height

• pole position
