The battery brand is ACDelco, model number 34-625, with a capacity of 69Ah (Amp-hours). Additional information: 1. The Buick LaCrosse is a model under the Buick brand. The front features a three-dimensional chrome waterfall grille, and the engine hood is adorned with Porthole chrome vents—inheriting Buick's traditional family design. 2. The Buick LaCrosse is the vertical successor to the SAIC-GM LaCrosse, retaining the original model's bold exterior while improving in design, power, and space. It also upgrades several luxury features, posing a comprehensive challenge to Japanese competitors like the Toyota Camry and Honda Accord, as well as German rivals such as the Volkswagen Passat and Magotan.

From a car repair perspective, the 2012 Buick LaCrosse typically uses an AGM-type Group 48 battery, with a CCA (Cold Cranking Amps) ranging between 740 and 760. The most common model is the ACDelco Professional AGM H6. This specification is required because the LaCrosse's high-power engine demands strong starting current, especially to avoid cold-weather starting difficulties. The battery is installed under the hood on the right side—just open it to check the label for confirmation. If unsure, consult the owner’s manual or have a professional scan the battery code to ensure compatibility with the original voltage and dimensions. When replacing, opt for an AGM battery for its durability, leak resistance, and suitability for frequent start-stop systems. Regularly inspect terminals for corrosion (wiping them with a cloth extends lifespan) and replace every 3-5 years to prevent roadside breakdowns.

When driving my 2012 Buick LaCrosse, I used the factory-recommended ACDelco AGM H6 battery, which is a Group 48 size. This battery has a CCA of approximately 750A, providing exceptionally reliable starts in winter. You can pop the hood and check the label on the battery for the specific model—it usually indicates 'Battery Group Size 48H6.' If you can't find the manual, simply take a photo and show it to a repair shop or use an online vehicle-matching tool by entering '2012 Buick LaCrosse,' and it will automatically display the correct model. Replacing it is straightforward, but remember to disconnect the power before DIY to avoid short-circuit risks. AGM batteries are slightly more expensive but more reliable. I replaced mine once, costing over 1,000 RMB, but it lasted four years without issues. Always avoid leaving headlights on to prevent draining the battery and affecting startup. Make it a habit to check the voltmeter—if the reading drops below 12V, it’s time for a replacement.

As a hands-on person, I believe the 2012 Buick LaCrosse battery model is Group 48 AGM, similar to the H6 specification. The CCA standard is around 740, ensuring quick starts. You can directly check the label on the old battery or use an auto parts website to search for the matching model by entering the vehicle's year and make. I often use O'Reilly Auto Parts' online tool—entering '2012 Buick LaCrosse' displays recommended brands like ACDelco or Optima. Opt for an AGM type for better resistance to high temperatures and vibrations, ideal for city stop-and-go driving. Before replacement, test the battery life; a voltmeter will quickly show the remaining capacity. If replacing it yourself, remember not to reverse the positive and negative terminals, and clear any fault codes after installation. If on a budget, compatible brands can save you some money.
