What is the battery specification for the Buick GL8?

[VincentFitz]

The battery specification for the Buick GL8 is 80D26R 12V 70A. The battery, also known as a storage battery, is a device that converts chemical energy into electrical energy. Its function is to supply power to the engine. When the vehicle is about to start, the battery discharges to provide power to the starter, which in turn drives the flywheel and crankshaft to start the vehicle. The dimensions of the Buick GL8 are 5256mm in length, 1878mm in width, and 1776mm in height, with a wheelbase of 3088mm. It is equipped with a 3.0L VVT V6 engine, delivering a maximum horsepower of 178 and a top speed of 168 km/h, paired with a 9-speed automatic transmission.

Speaking of the Buick GL8's battery specifications, I've driven several of these vehicles and found that they typically come equipped with a 12-volt, 70-ampere-hour (Ah) AGM battery, which provides excellent support for the start-stop system. AGM batteries are far more durable than standard lead-acid ones and can handle frequent starts, especially for owners who do a lot of short city driving—keeping the battery from frequently running low is crucial. I think it’s a good idea to regularly check the voltage yourself; a healthy reading should be above 12 volts, and if it drops below 11 volts, it’s time for a replacement. When buying a battery at an auto parts store, always opt for the original factory model—don’t cheap out and end up with a no-name brand. Battery terminals are prone to corrosion, so keeping them clean can prevent starting issues. Checking the terminals every six months is a smart way to save money in the long run.

Buddy, I just replaced the battery in my GL8 with a 12V72Ah AGM model. The CCA rating is around 760 amps, and it starts reliably even in cold weather. Changing the battery yourself isn't difficult—just turn off the ignition and unplug the connectors—but make sure to get the right model. Don't skimp on costs; buy from a reputable store. Daily maintenance is simple: avoid excessive sun exposure in summer to prevent overheating, take longer drives in winter to keep it charged, and be aware that frequent start-stop usage can shorten battery life. If the engine cranks slowly or the infotainment screen goes black, check the battery voltage. If it's below 12 volts, there's likely an issue—replace it promptly to avoid bigger problems.

Our family uses a GL8 for commuting and picking up the kids, so the battery must not fail. The specifications are 12-volt 70Ah AGM type, which is reliable and safe. AGM batteries are suitable for start-stop functions, reducing the risk of breakdown. During maintenance, the technician often reminds us to check the battery health, with a stable voltage above 12 volts being ideal. Choosing an OEM-matched battery is hassle-free, and for maintenance, just make sure the terminals don’t rust—clean them with a soft brush. If the voltage drops too low and the car won’t start, it would be troublesome for the kids to be late.
