### How to choose your Kronobat device battery

Check the voltage (6V or 12V), the capacity (Ah) and the exact dimensions of your current battery before replacing it: in security electronics and medical equipment, a lower capacity shortens runtime during a power cut. Use the [comparison tool](/gb/comparator) to check at a glance which Kronobat model matches your equipment.

## Frequently asked questions about Kronobat device batteries

### **Are they compatible with any alarm or small UPS?**

Yes, as long as the voltage (6V or 12V), a similar or higher capacity (Ah) and the physical dimensions match the equipment's battery compartment.

### **How long does a Kronobat device battery last?**

In backup (float) use, the typical service life of this type of sealed AGM/GEL battery is usually several years, depending on temperature and how often power cuts occur.

### **What's the difference between AGM and GEL in these models?**

AGM delivers somewhat higher current peaks and is more common in alarms and UPS units; GEL better tolerates repeated deep cycling, common in equipment that discharges and recharges daily.

### **Do they need maintenance?**

No, they are sealed batteries (VRLA): there's no need to check or top up electrolyte, and they can be installed in any orientation without leak risk.
