Do I Need to Disconnect My Battery?

Do I Need to Disconnect My Car Battery? Not With PriorityStart!

If you’re googling “how to disconnect a car battery,” that usually means one thing:
You’re trying to avoid a dead battery during storage, repair, or long-term parking.

But manually disconnecting a battery is inconvenient, often unsafe, and can cause issues with vehicle electronics. Luckily, technology offers a much better solution.

PriorityStart! protects your battery automatically — install it and forget it.

Why Drivers Think About Disconnecting the Battery

People commonly consider disconnecting the battery when:

• Leaving for a long trip
• Parking the car for winter
• Storing a classic or weekend vehicle
• Trying to stop parasitic drain

No matter what your reason is, the goal is usually the same: prevent the battery from draining.

The Problems With Manually Disconnecting Your Battery

Disconnecting your battery can result in several drawbacks:

• Loss of radio presets and memory settings
• Possible error codes
• Navigation system resets
• Vehicle modules needing to relearn
• Risk of sparks
• Using tools near the battery
• Airbag or electrical system warnings
• Difficulty reconnecting later

And for EV owners, disconnecting the 12V battery can disable important safety systems.

Why PriorityStart! Is the Better Option

PriorityStart! makes all of this unnecessary.

Instead of pulling battery cables every single time, PriorityStart!:

• Requires zero maintenance

It’s like having a smart, automatic battery disconnect built right into your car — without the major drawbacks.
