What does it mean when the Mazda stop green light stays on?

Possible insufficient battery power. Below is relevant information about the battery: 1. Working principle: The battery, also known as a storage battery, is a type of cell that converts chemical energy into electrical energy. Typically, when people refer to a battery, they mean a lead-acid battery. This is a type of battery mainly made of lead and its oxides, with a sulfuric acid solution as the electrolyte. 2. Precautions: Avoid storing the battery in a discharged state. A discharged state refers to when the battery is not recharged promptly after use, which can easily lead to sulfation. Lead sulfate crystals can form on the plates, blocking the ion channels and resulting in insufficient charging and reduced battery capacity. The longer the battery remains idle in a discharged state, the more severe the damage. When the battery is not in use, it should be charged once a month to extend its service life.
As a Mazda owner, I've encountered a similar issue. The green "STOP" light is actually the indicator for the i-stop system. When it stays illuminated, it means the idle stop function is enabled—a fuel-saving feature that automatically shuts off the engine when stationary and quickly restarts it when moving. Normally, the green light indicates proper system operation. However, if it remains lit without the engine shutting off, it could signal a weak battery due to aging or a faulty sensor, requiring a dealership inspection. The i-stop system improves fuel efficiency, so maintaining battery health is crucial—avoid frequent short trips with multiple starts and adhere to regular maintenance to prolong its lifespan. Don't worry excessively, but address abnormalities promptly to prevent secondary failures.
From my years of car maintenance experience, the constant illumination of the Mazda stop green light is generally a normal signal of the i-stop system, which only activates under suitable conditions, such as appropriate air conditioning temperature and sufficient battery charge. However, if the green light stays on but the system doesn't work, it's necessary to check the battery status, sensors, or control unit faults, issues commonly found in older cars. During maintenance, ensuring the electrical system is functioning properly and cleaning the battery terminals can prevent false signals. The i-stop system is quite useful, saving about 10% of fuel, but you need to get used to the engine stopping and starting in traffic jams—it feels a bit odd, but it's actually very safe and reliable.
