No matter if you’ve got a coupe, convertible, or sedan, the 2008 Pontiac G6 GT takes a 600 CCA/90 RC Group 90 battery. It also doesn’t matter if you’re packing a 3.5L or 3.9L V6 engine under the hood.
There are three parts to this label and all of them indicate the battery size differently. Here’s the breakdown:
- CCA, or Cold Cranking Amps, measures how many amps a battery can deliver at 0°F for 30 seconds while maintaining at least 7.2 volts. With a rating of 600, the G6 GT’s battery is more powerful than the average car battery, but some specialty cold-starter batteries can go up to 1,000 CCA!
- RC, or Reserve Capacity, measures how long the battery can run your car on its own. In the event your alternator fails, 90 RC gives you an hour and a half to reach a garage.
- Group 90 batteries are medium-sized batteries with positive and negative terminals on either side of their tops. The batteries in this category measure approximately nine inches long, seven inches wide, and seven inches high (246 x 175 x 175 mm).
If you’re shopping for car batteries, you’re free to choose OEM or generic parts. However, the one thing you should never do is buy a battery from the wrong group. If it’s too big, you won’t be able to cram it in place. If it’s too small, it could jump around while you’re driving and break something.

.How to keep your 2008 Pontiac G6 GT battery healthy
The exact date your car fails to start and leaves you stranded depends on your driving habits. With the right ones, you can
save money on gas
and new car batteries. Here are the most important things to keep in mind:- Regular driving keeps the battery happy. When your car is running, the alternator recharges the battery; if it's parked, the battery gets nothing. Get your car out at least once a week for 15 minutes to keep it topped up.
- You might need to top it up yourself. You should leave your car's battery plugged in if you intend to leave the car in storage. You can reconnect it as soon as you return.
- Lights cost money. Headlights, signal lights, fog lights, and interior lights all suck power from the battery. Don't leave your car without turning everything off.
- Your battery can die by a thousand cuts. Lights, speakers, lighters, chargers, and smoothie makers all draw power from the battery. You should disconnect them before you leave your car.
- Sticking to yourcar maintenance scheduleis cool, actually. You might not realize it, but inefficient parts or malfunctioning lights could be siphoning power from the battery. Keeping your car in good shape will make your battery last longer.
