Question type: General

Does it need a special type of battery

4 Answers


All cars do and yours is a size 78

Just ask for a size 78 no need for any other special requirements


That's all you really need, but also for your own comfort, at parts stores and walmart, they can look up the year, make, model of your car to make sure you get the right battery.

Yes, as it is located under the back seat bottom cushion it requires a vented battery, you can do away with the vented system if you go to a gel cell type battery, they last much longer than conventional lead acid batteries and are much safer when installed inside the vehicle, no acid corrosion. I have been very pleased with these type of batteries in my wife's caddie, absolutely no smell, no corrosion, and excellent cranking power. Yes they do cost more but well worth the piece of mind.
