What model battery does the Buick Regal use?
4 Answers
The original battery for the Buick Regal is the L2-400 model, a genuine maintenance-free battery provided by SAIC-GM. It features a fully sealed design, long service life, excellent performance, and high reliability, ensuring smooth operation for every trip. It also performs well in harsh environments with effective cold-start capabilities and voltage stabilization. Below are details about the Buick Regal: 1. The new Regal has upgraded configurations compared to previous models, including an active grille shutter for all variants, an increase to two front USB ports, and the replacement of the Linen Gold paint with new Titanium Gray and Shadow Gray options, enhancing the overall premium feel of the lineup. 2. In terms of powertrain, the new model continues to offer 1.5T and 2.0T engines. The 1.5T engine delivers a maximum power of 125kW (170PS) and peak torque of 252N·m, while the 2.0T engine produces 192kW (261PS) maximum power and 350N·m peak torque.
I've been driving a Buick Regal for nearly ten years, and the battery model is usually AGM Group 48, which is H8 size, especially suitable for start-stop system models. When using traditional lead-acid batteries before, they were prone to problems, but AGM batteries are more durable and leak-proof. I replace them every three to five years and recommend the original AC Delco brand, with a matching voltage of around 12 volts. Changing the battery isn't difficult, but remember to disconnect the negative terminal first to avoid short-circuiting and damaging the computer system. The battery is located on the right side under the hood. Just buy one with a matching CCA (cold cranking amps) rating—don’t go for cheap, low-quality ones, or you’ll have trouble starting in cold weather. Regularly checking for electrode corrosion is a must; a bit of baking soda can help clean and maintain it well.
Hey, I just got myself a Buick Regal, and the battery model is AGM H8 or Group 48. It's not small in size but super easy to replace on my own. I went to the auto parts market and found an Optima brand, which is affordable and practical, but make sure to check the CCA parameter—700A or above is safer. Don’t get the wrong model, though; older Regals might differ, so checking the owner’s manual is the most accurate. When the battery gets old, the lights will flicker as a sign it’s time for a replacement. I usually check it every two years and measure the voltage before winter. Before replacing, turn off the engine and lock the car to avoid the alarm system going off. By the way, adding a small blanket over the terminals works wonders for frost protection. After changing the battery, the car starts quickly, accelerates smoothly, and feels revitalized overall.
Speaking of the Buick Regal, it is equipped with an AGM-type battery, commonly in Group 48 size. AGM batteries offer significant advantages, such as low internal resistance, fast charging, and no risk of leakage, making them particularly suitable for high-end models with auto start-stop systems. The CCA (Cold Cranking Amps) requirement is around 720 amps—do not mistakenly use a standard battery, as it may mislead the system. For long-term use, it is recommended to maintain the battery with a smart charger to avoid deep discharge, which can shorten its lifespan. When replacing the battery, ensure the positive and negative terminals align with the factory settings and tighten the connections to prevent loosening. Check that the voltage remains above 12.6 volts for safety, and regularly clean dust to avoid cooling issues.
