Signs: difficult starting (especially cold), battery warning light, weak electrical equipment. Have voltage and capacity tested.
What's the difference between AGM, EFB, and standard batteries?
AGM: high performance, Start-Stop, more expensive. EFB: intermediate, entry-level Start-Stop. Standard: vehicles without Start-Stop.
Can I recharge a dead battery?
Yes with a suitable charger. If it no longer holds charge or plates are sulfated, replacement is necessary.
