## VARTA Silver Dynamic AGM — the reference AGM

The code under the bonnet (A6, D52, E39, F21, G14, H15) is exactly VARTA — just replace with the same reference.

### Compatibility and replacement

Direct replacement for Varta A6, D52, E39, F21, G14, H15 and equivalents [Tudor AGM Microhybrid](/gb/batteries-tudor-agm-microhybrid) / Exide AGM at matching DIN code. **Important**: cars with BMS require *battery registration / coding* via OBD — without it the new battery ages prematurely.

### AGM vs EFB: when each

AGM if the label/manual says AGM. EFB enough if basic Start-Stop with no regen braking. **Never downgrade AGM to EFB** — the management system is calibrated for the AGM curve and EFB will not survive the cycling.

### Frequently asked questions

### **How do I know my car needs AGM?**

Read the current battery label. If it says AGM, AGM is mandatory. Also: 99% of BMW/Mercedes/Audi/VAG with regen-brake Start-Stop are AGM.

### **How long does a Silver Dynamic AGM last?**

5-7 years if properly sized. AGM withstands 3-4x more cycles than SLI, ideal for Start-Stop.

### **Does it need coding?**

On BMW, Mercedes, Audi, VAG and most post-2010 premium cars, yes. The BMS needs a reset to apply the correct charge curve.

### **Difference vs Powersports AGM?**

Silver Dynamic AGM is for cars with Start-Stop. [Powersports AGM](/gb/batteries-varta-powersports-agm) is the motorcycle AGM with a different form factor and terminals.

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