No maintenance required
-
Theoretical battery life longer than a standard battery
⚠️ Disadvantages to consider
-
Higher price (+30/50% compared to a traditional one)
-
Sensitive to charging errors: compatible smart chargers are needed
-
Not necessary on vehicles with basic Start&Stop or without Start&Stop
⚙️ AFB/EFB Batteries: Affordable but Advanced Alternatives
