i-stop needs a start-stop battery
Mazda's i-stop system turns the engine off at lights and restarts it when you release the brake. The battery has to support the cabin and restart the engine again and again, so i-stop models use EFB or AGM batteries. A flooded battery tends to trigger the i-stop warning light and stops the system working. Mazda's i-stop batteries often carry codes such as Q-85 or S-95 on the label; match that code or its equivalent.
