Installation Tips For Your 350Z
Installing a new battery in the 350Z is straightforward. But there are a few things you should know to avoid problems.
- Disconnect the negative terminal first. This prevents short circuits if your wrench touches metal.
- Remove the battery hold-down bracket. It’s a simple metal bar that clamps the battery in place.
- Lift the old battery out. Be careful, they are heavy. Use a battery strap if you have one.
- Clean the battery tray. Use a wire brush to remove any corrosion or debris.
- Place the new battery in the tray. Make sure the positive terminal is on the right side.
- Reinstall the hold-down bracket. Tighten it snugly but don’t overtighten.
- Connect the positive terminal first. Then connect the negative terminal.
- Apply dielectric grease to the terminals. This prevents corrosion.
After installation, start the engine and check that everything works. Your radio presets and clock may need to be reset. This is normal after disconnecting the battery.
Common Battery Problems In The 350Z
350Z owners report a few specific battery issues. Knowing these can help you diagnose problems early.
Parasitic Drain
The 350Z has a known parasitic drain issue. The BCM (Body Control Module) can draw power even when the car is off. This can kill a battery in a week if you don’t drive the car regularly.
To test for parasitic drain, use a multimeter. Set it to amps and connect it in series with the negative battery cable. A draw of more than 50 milliamps is excessive. Track down the source by pulling fuses one by one.
Heat Damage
The battery in the 350Z sits close to the exhaust manifold. Heat can boil the electrolyte in flooded batteries. This leads to sulfation and premature failure.
AGM batteries handle heat much better. The glass mat separators keep the electrolyte in place. This prevents dry-out and extends battery life.
Vibration Failure
The 350Z’s suspension is stiff. This transmits vibration to the battery. Flooded batteries can shed active material from the plates due to vibration. This causes internal short circuits.
AGM batteries are more resistant to vibration. The glass mat holds the plates in place. This makes them ideal for sports cars like the 350Z.
Battery Maintenance Tips
Even the best battery needs some care. Follow these tips to get the most life out of your 350Z battery.
- Keep the terminals clean. Corrosion creates resistance and reduces starting power.
- Check the battery voltage monthly. A healthy battery reads 12.6 volts or higher when resting.
- Use a battery tender if you store the car. This keeps the battery fully charged without overcharging.
- Don’t let the battery discharge completely. Deep discharges damage AGM batteries.
- Replace the battery every 4-5 years. Even if it still works, internal resistance increases over time.
Battery Size And Fitment Details
The 350Z uses a Group 35 battery. The dimensions are approximately 9.06 inches long, 6.88 inches wide, and 8.94 inches tall. This includes the terminal posts.
Some aftermarket batteries may have slightly different dimensions. Always check the fitment before buying. The battery tray in the 350Z is not adjustable.
If you install a battery that’s too tall, the hood may not close properly. This can damage the battery and the hood. Stick with Group 35 size to avoid issues.
Cold Weather Performance
If you live in a cold climate, CCA matters a lot. The 350Z’s engine needs strong cranking power when temperatures drop below freezing.
The Optima RedTop and Odyssey 35-PC1400T both excel in cold weather. Their AGM construction provides consistent power even at -20°F. Flooded batteries lose about 60% of their CCA at 0°F.
Consider a battery heater if you live in extreme cold. This keeps the battery warm and maintains cranking power. Some aftermarket battery heaters wrap around the case.
Warranty Considerations
Battery warranties vary widely. Most flooded batteries come with a 2-3 year free replacement period. AGM batteries often have longer warranties.
The Odyssey 35-PC1400T has a 3-4 year full replacement warranty. The Optima RedTop has a 3 year free replacement warranty. Interstate and ACDelco offer similar terms.
Keep your receipt and register the battery online. This makes warranty claims easier. Some retailers prorate the warranty after the free replacement period ends.
Price Comparison
Battery prices fluctuate based on location and availability. Here’s a general idea of what you’ll pay for each option.
- Optima RedTop: $200-$250
- Odyssey 35-PC1400T: $250-$300
