Before You Jump Start a Battery: Know When It’s Unsafe
Jump starting works only if the battery is structurally sound. Never attempt a jump start if you see:
- Cracks, leaks, or bulging
- A frozen battery
- Severe corrosion or loose terminals
These conditions increase explosion risk and signal battery failure.
At Edmonds, we inspect and test batteries before recommending a jump or replacement. Safety always comes first.

Step-by-Step: How to Jump Start a Dead Battery
The Correct Order Matters
Follow these steps exactly to protect your vehicle and electronics.
Step 1: Position the Vehicles
Park close enough for the cables to reach, but don’t let the vehicles touch. Turn off both engines and engage parking brakes.
Step 2: Connect the Positive Cables
- Connect the red clamp to the positive (+) terminal on the dead battery
- Connect the other red clamp to the positive (+) terminal on the working battery
Step 3: Connect the Negative Cable Safely
- Attach the black clamp to the negative (–) terminal on the working battery
- Attach the other black clamp to an unpainted metal surface on the vehicle with the dead battery, NOT the battery itself.
This grounding step reduces spark risk near battery gases.
Step 4: Start the Working Vehicle
Let it run for several minutes to transfer charge.
Step 5: Start the Dead Vehicle
If it doesn’t start right away, wait another minute or two and try again. Avoid extended cranking.
Step 6: Remove Cables in Reverse Order
Remove the cables carefully, reversing the connection order. First remove the black clamp, then the red clamp.

Jump Starting with a Portable Jump Starter
Portable jump starters allow you to jump start a dead battery without another vehicle. These units work well when sized correctly for your engine and battery type.
We help customers choose jump starters that match real-world needs, not underpowered gadgets. Ask Edmonds Batteries which jump starter fits your vehicle. Call us at 604-534-7995
When a Jump Start Isn’t Enough
A jump start only restores a temporary charge. The battery likely reached the end of its service life, or the charging system needs attention, if your vehicle:
- Needs frequent jump starts
- Cranks slowly
- Dies shortly after starting
We test batteries and charging systems to identify the real cause and avoid unnecessary replacements.
Stop guessing. Get your battery and charging system tested today.
