What battery does the Buick GL8 use?

[DelJulian]

The battery model for the Buick GL8 is 80D26R12V70A. The battery is a crucial component in a vehicle, supplying power to all electronic devices when the engine is not running. After the engine is started, the alternator takes over to power the electronic devices and also charges the battery. Here are some relevant details: 1. The battery is responsible for starting the engine. During engine startup, the ignition system, fuel supply system, and starter all require electricity to function. 2. The Buick GL8 is a 5-door, 7-seater MPV with body dimensions of 5238mm in length, 1878mm in width, and 1776mm in height, and a wheelbase of 3088mm. This model is equipped with a 2.0T turbocharged engine, delivering a maximum power of 174 kW and a maximum torque of 350 Nm, paired with a 9-speed automatic transmission.

I've been driving a GL8 for several years and have quite some experience with its battery. Most GL8 models come with start-stop functionality, requiring an AGM battery, typically around 12 volts and 60 ampere-hours. Regular lead-acid batteries tend to fail easily during start-stop cycles, whereas AGM batteries are more durable. When replacing the battery, make sure to choose one with matching capacity—too high or too low can affect engine performance. Regularly check the battery voltage during use, and avoid driving when it's undercharged to prevent starting difficulties. It's advisable to have the battery life tested during routine maintenance at a 4S shop, as replacement is usually needed every 3-5 years. If you're not confident in handling it yourself, it's best to visit a professional shop to avoid damaging the ECU system. In short, opting for an AGM-type battery for your GL8 is a must—don't skimp on cost.

My GL8 had a battery issue last time and broke down on the road. It turned out the original battery was an AGM type. These batteries are complexly designed for start-stop functions, typically with a capacity of 60Ah to 70Ah and 12 volts. Don’t replace it with a regular battery—start-stop systems draw high current, which can easily damage components. When replacing, check the VIN or consult a 4S shop to ensure the size and model match. I replaced mine with a branded AGM battery at a quick-service shop—cost a bit but saved hassle. Daily use: remember to turn off headlights to avoid power drain. During maintenance, test battery health and address issues early if found.

Briefly about the GL8 battery issue: Start-stop models must use AGM batteries with 12V specification, typically ranging from 60-70Ah in capacity. Regular batteries can't handle frequent start-stop cycles, and using the wrong type may trigger fault codes. Check the OEM model or manual to ensure parameter consistency. Opting for branded parts is more reliable to avoid future hassles.
