What is the battery model used in the Buick Regal?

[StMarcus]

The battery model used in the Buick Regal is L2400, which is a fully sealed maintenance-free battery with long service life, excellent performance, and high reliability, ensuring smooth travel every time. The Buick Regal is a B-class sedan launched by Buick, with dimensions of 4913mm in length, 1863mm in width, and 1462mm in height, and a wheelbase of 2829mm. In terms of appearance, this car features a waterfall-style grille, with a metal-textured three-shield emblem embedded in the center, complemented by three-dimensional combination headlights on both sides. The 7-shaped LED daytime running lights are more visible in low light conditions than conventional ones. A central line on the engine hood starts from the grille and ends at the base of the windshield, echoing the teardrop-shaped side mirrors on both sides of the body.

The commonly used battery models for the Buick Regal are typically 94R or H6, depending on the year and engine displacement. For example, when I was repairing cars, I noticed that models after 2015 mostly use H6 specification AGM batteries, with a capacity of around 60Ah and a CCA (Cold Cranking Amps) of over 650 amps, which is suitable for cold starts. When replacing the battery, it's best to first turn off the engine, disconnect the negative terminal followed by the positive, loosen the bracket with a wrench, and then remove the old battery. Before installing the new one, clean the terminals to prevent corrosion. AGM batteries are more durable than traditional flooded types, maintenance-free, and can handle engine vibrations, lasting three to five years without issues. I've replaced them a few times myself, and brands like ACDelco or Optima are reliable—don’t skimp by buying cheap online to avoid mismatched sizes that won’t fit the battery box. Regularly check the voltage; 12.6V is considered healthy, and if it drops below 12.4V, inspect the charging system or alternator.

I've been driving a Buick Regal for five years, originally equipped with an H6 battery, which worked great. It lasted about four years with daily city commuting, without major issues. When it was time to replace the battery, I opted for the same AGM model, which offers better cold resistance—no sluggish starts in winter. It's a bit pricier but worth it; don't skimp on small expenses that could affect driving safety. DIY replacement is straightforward—just follow a 10-minute YouTube tutorial. Remember the disconnection sequence: negative terminal first to prevent short circuits. The battery is usually located on the right side of the engine bay, just lift the cover. For maintenance, check electrolyte levels—older types need water top-ups, while newer AGM batteries are hassle-free. If headlights flicker or the car starts slowly, test the battery immediately. Always keep an emergency jump starter handy, especially for long trips—better safe than stranded.

Don't just memorize models. From my repair experience, most Buick Regal batteries are either 94R or H6, but always check the manual or hood label for accuracy. AGM types are now mainstream and support auto start-stop functions. Simple way to check battery health: delayed cold starts or dim lights may indicate issues. When buying, look for CCA rating - at least 600 to prevent winter failures. I recommend Delphi brand - reliable and affordable. Quick replacement steps: disconnect negative terminal, remove bracket, install new battery, then reset the car's computer to avoid error codes. Don't mix up sizes - standard 94R measures about 240mm long, 175mm wide, and 190mm tall. After replacement, remember to drive around to recharge it.
