Understanding EFB Technology

EFB stands for Enhanced Flooded Battery, a type of lead-acid battery that is an upgrade over conventional flooded batteries. It is specifically designed for start-stop vehicles, where the engine automatically turns off when idling and restarts when the driver releases the brake or engages the accelerator.

Unlike standard lead-acid batteries, EFBs have a more durable design with improved cycle life and charge acceptance. They achieve this through:

• Thicker positive plates for better durability
• A special carbon additive in the negative plate to enhance charge efficiency
• Improved separators and electrolyte circulation, reducing sulfation and increasing battery life

EFB technology provides an affordable alternative to AGM (Absorbent Glass Mat) batteries, making it suitable for mid-range vehicles with start-stop functionality.

Maintenance Tips for Longer Battery Life

To maximize the lifespan and efficiency of your Globatt N55L (EFB) 50AH, follow these maintenance tips:

1. Keep Battery Terminals Clean

   • Corrosion buildup can reduce battery efficiency. Clean terminals with a baking soda solution and apply anti-corrosion grease.

2. Avoid Deep Discharges

   • EFB batteries perform best when not completely discharged. Keeping it charged above 50% ensures optimal lifespan.

3. Check Battery Voltage Regularly

   • Use a multimeter to check if the battery voltage remains above 12.4V when the engine is off.

4. Ensure Proper Charging System Functionality

   • Have your vehicle’s alternator and voltage regulator checked to avoid overcharging or undercharging issues.

5. Avoid Excessive Heat Exposure

   • Heat accelerates battery wear, so park in shaded areas when possible.

6. Drive Regularly

   • Short trips without proper charging cycles can shorten battery life. If your car remains parked for extended periods, consider using a trickle charger.

Comparison: EFB vs. AGM vs. Conventional Batteries
