## Description

The **12 V AGM battery for electronic devices** is the silent power source behind everyday critical kit: **alarm panels** Honeywell, DSC, Risco, Visonic, Texecom; **EPOS and weighing scales** Dibal, Bizerba, Mettler Toledo; **CCTV and access control**; biometric readers; portable field instrumentation; electronic toys and models.
Sealed 12 V AGM **1.2 to 26 Ah** in compact formats (NP-12, BP12-XX, FT-XX) optimised for float with very low self-discharge.

## How to choose the right 12 V AGM

What matters is **capacity in Ah** and **physical dimensions (L × W × H)** with polarity and F1/F2 terminal format. Most residential alarm panels need 7-12 Ah; EPOS 7-12 Ah; small home UPS 7-9 Ah. When replacing the alarm battery, **always the same Ah or higher** — going down cuts blackout autonomy.

### Table by application

### Frequently asked questions

### **How often replace the alarm battery?**

Every 3-5 years on a standard residential alarm. The panel's "low battery" signal triggers when float voltage drops below threshold.

### **Can I fit a higher Ah?**

Yes, as long as it fits physically. Higher Ah gives more blackout autonomy; never below original.

### **How long does shipping take?**

Standard delivery **1 to 5 working days** to your country. We process orders within 24h.
