What is the battery model for the Regal?
4 Answers
The original battery for the Buick Regal is the L2-400 model, a genuine accessory battery provided by SAIC-GM. Here are some additional details: 1. This battery is a fully sealed, maintenance-free type with a long service life, excellent performance, and high reliability, ensuring smooth travel every time. 2. In harsh conditions, it offers superior low-temperature starting and voltage stabilization effects, providing better voltage support for all electronic devices in the vehicle. Additional information: The typical service life of a Buick Regal battery is 2 to 3 years. However, to ensure trouble-free travel, the battery terminals should be checked during every oil change to ensure stability. Additionally, the battery charge should be inspected regularly. Most vehicles come with maintenance-free batteries. When replacing the battery, the new one should have the same part number as indicated on the original battery's label.
The Buick Regal's battery model is generally an H6 AGM or Group 48 size battery, depending on your vehicle's year. I drive a 2018 Regal, and the battery label shows H6, with a capacity of 90Ah and a cold cranking current of around 800A, suitable for the start-stop system. Older models, like those before 2010, might use standard lead-acid batteries, but AGM batteries are more durable and energy-efficient. To verify the model, check the label on the side of the battery under the hood or refer to the electronic version of the owner's manual. I often remind friends not to buy the wrong model, especially for start-stop versions, as they have higher battery requirements; otherwise, the battery drains quickly. Regularly clean the terminals to prevent rust and test the voltage every two years—this can extend the battery's lifespan to about five years. Choose brands like ACDelco or Varta that match the original specifications.
In auto repair shops for many years, the commonly seen Regal battery is the H6 AGM type, especially for models with start-stop systems after 2015, with a Group 48 size and approximately 90Ah capacity. The model number is engraved on the battery label and can be identified at a glance—do not mix it with regular batteries. The CCA (Cold Cranking Amps) value should be above 700A; anything lower may cause starting difficulties. During inspections, a normal voltage reading should be 12.6V. If the battery is found to be undercharged, replace it early to avoid damaging the starter. Customers often overlook terminal corrosion—cleaning off rust with a toothbrush can extend the battery's lifespan. It is recommended to replace it with a new one matching the original factory specifications, typically costing between 500-1000 RMB. Safety first—don’t take risks by delaying.
Researching car modifications, the majority of Regal battery models are H6 AGM, which became popular starting from the 2017 model year, equipped with start-stop systems supporting high current output. Older models may use regular battery types. Quick lookup methods include checking the manual or battery label. AGM batteries are maintenance-free but more expensive, with advantages being durability and less leakage. My experience suggests choosing a CCA rating above 650A and ensuring precise dimensions to avoid modification issues. Simple maintenance includes testing the battery charge monthly and disconnecting power when parked to prevent drainage. Model differences are minor, the key is matching the vehicle's requirements.
