What is the battery model for the Buick GL8?
2 Answers
The battery model for the Buick GL8 is 80D26R 12V 70A. The battery is a crucial component in a car. When the engine is not running, the battery supplies power to all the vehicle's electronic devices. After starting the engine, the alternator takes over to power the electronic devices and also charges the battery. The battery is a wearable part that requires regular replacement. Typically, a battery can last 3 to 4 years, but many car batteries fail before reaching that lifespan due to incorrect usage habits by the owner. To prolong battery life, avoid using the vehicle's electronic devices for extended periods when the engine is off.
I remember driving a Buick GL8 for several years and just replaced the battery myself last year. It uses an 80Ah AGM battery, possibly with a model number like S97B80, depending on the year. Typically, it's hidden in a small compartment under the hood on the right side—you'll need to open it and unscrew some bolts to see the label. Don't go for cheaper options when choosing; the size must match the original slot, or it won't fit properly and may cause severe shaking during startup. AGM batteries are more durable and can last five to six years without maintenance. Last time I replaced it with an incompatible one, it caused a bunch of charging issues, costing me extra for repairs. I recommend measuring carefully before buying or taking a photo of the old battery to match it at the store. Make it a habit to check for terminal corrosion and clean dust to prevent leakage—it gives peace of mind on long trips.
