To make sure you pick the right lead-acid battery (batteries au plomb) for your car, boat, or backup system, check your current battery’s voltage (usually 12V for most cars), size, terminal type, and capacity (Ah). You’ll find these details in your vehicle or device manual, or on your existing battery label. If you’re still unsure, you can always contact the Accessoires Energie team with your vehicle or equipment model and our experts will guide you to the perfect fit.
