Mazda CX4 battery model specifications: The original battery of Mazda CX4 is a 65AH start-stop battery. The battery capacity of Mazda CX4 is 55mA. The designed lifespan of the battery is 27 months. Generally, family cars are more economical, and new car batteries can last 3-4 years. However, after the first replacement, it is usually necessary to replace the battery every 2 years or so. The working principle of the battery is to convert chemical energy into electrical energy. The battery used in cars refers to lead-acid batteries, which are mainly made of lead and its oxides. To check the condition of the battery, inspect whether the battery casing is bulging, leaking, or has broken partitions, and check for corrosion on the battery terminals. If any of these phenomena are present, it indicates that the battery is dead and needs to be replaced. Test the battery voltage: after charging for two hours, check the voltage of each battery cell every 20 minutes. If it is below 13, the battery has a problem. During discharge, test every 10 minutes in three intervals. If the discharge time is faster than other batteries and the voltage drops below 10V, the battery has a problem. Check if the battery is "dehydrated" or blackened. After charging the battery for 3-6 hours, if the charger's red light remains on, it indicates severe "dehydration" of the battery.
I recently replaced the battery in my Mazda CX-4. This car originally comes equipped with a Q-85 model battery. When you open the hood, you can see the battery located above the left front wheel, with a label clearly marked 6-QW-65, indicating a 65 amp-hour capacity. There might be slight variations between different model years, for example, versions with auto start-stop after 2019 may require an EFB battery. It's recommended to choose a battery of the same capacity from brands like Varta or Yuasa when replacing. Last time I bought model 56318 online with installation included for just over 400 yuan. If you're doing it yourself, be aware that disconnecting the battery might reset the car's computer, so it's better to have a professional handle it. Also, avoid running the AC while playing with your phone after turning off the engine; this can extend the battery life by over two years.
The Mazda CX-4 typically uses a Q-85 model battery, corresponding to 65Ah capacity and 550A cold cranking amps. In actual maintenance, it's common to find the original vehicle equipped with a 6-QW-65 specification, which is clearly marked on the side label of the battery. It's crucial to note that vehicles with start-stop functionality require EFB batteries, while standard models can use traditional lead-acid batteries. When replacing, always verify the bracket dimensions—one owner nearly couldn't fit the battery due to buying the wrong model. We recommend opting for VARTA Blue or GS Unified brands, as their longer warranty periods offer peace of mind. If you're not comfortable replacing it yourself, Jingdong Car Care can dispatch a technician for on-site installation within half an hour of placing an order.
