🔋 Century Q85MF Start-Stop EFB Battery – 12V 550CCA Enhanced Flooded Battery | Stop-Start Ready | 24-Month Warranty

🚗 Built Specifically for Stop-Start Technology

Modern vehicles with stop-start systems place far greater stress on the battery than conventional cars. Frequent engine restarts, increased electrical demand, and longer idle periods mean a standard flooded battery simply won’t last.

The Century Q85MF EFB Battery is engineered specifically for these conditions, delivering:

• Reliable cold starting

• High cycle durability

• Stable voltage under repeated stop-start events

If your vehicle was factory-fitted with an EFB battery, this is the correct and recommended replacement.

🔍 What Is EFB & Why It Matters

Enhanced Flooded Battery (EFB) technology is an upgraded version of traditional lead-acid batteries, developed for standard stop-start vehicles.

Compared to conventional batteries, EFB provides:

• ✅ Up to 2× higher cycling performance

• ✅ Improved charge acceptance

• ✅ Stronger internal grid design

• ✅ Better resistance to partial state-of-charge operation

⚠️ Important:
Downgrading from EFB to a normal flooded battery can cause:

• Short battery life

• Stop-start system malfunction

• Warning lights or fault codes

❓ EFB vs AGM – Which Do You Need?

• EFB → Standard stop-start vehicles (most common)

• AGM → Advanced stop-start or regenerative braking systems

👉 If your vehicle was fitted with EFB, replacing it with EFB is correct.
AGM is not required unless specified by the manufacturer.
