If your Shark cordless vacuum isn’t holding a charge like it used to, you might be wondering how to change battery in shark cordless model. It’s a common fix that can save you the cost of a new machine. This guide will walk you through the entire process safely and clearly, whether you have a Shark Vertex, ION, or WandVac model.
Replacing the battery yourself is usually straightforward. Most Shark cordless vacuums are designed with user-replaceable batteries in mind. With a few basic tools and the right replacement part, you can have your vacuum running like new in under 30 minutes. Let’s get started on bringing your cleaning power back to full strength.
How To Change Battery In Shark Cordless
Before you start taking things apart, there are a few essential steps to complete. Preparation is key to a smooth and safe battery replacement. Rushing in can lead to mistakes or even damage your vacuum.
What You’ll Need to Get Started
Gathering your tools and parts first makes the job much easier. You won’t have to stop halfway through to search for something. Here’s your checklist:
- The correct replacement Shark battery. This is the most critical item.
- A small Phillips head screwdriver. This is the most common tool needed.
- A clean, flat workspace with good lighting.
- A small container for holding screws (so they don’t get lost).
- Your vacuum’s user manual (helpful for model-specific details).
Finding the Right Replacement Battery
Not all Shark batteries are the same. Using the wrong one can damage your vacuum or pose a safety risk. Here’s how to find the perfect match:
- Check the model number on your vacuum. It’s usually on a sticker on the main body or near the charging port.
- Look at the old battery itself. It should have a part number printed on it (e.g., XBATF160, SV1106).
- Purchase from Shark’s official website, an authorized retailer, or a reputable parts supplier. Avoid cheap, generic batteries as they may not have the same safety protections.
Safety First: Important Precautions
Lithium-ion batteries are safe when handled correctly, but they require respect. Please follow these safety rules:
- Always turn the vacuum off before starting.
- Let the battery cool down if you’ve just used the vacuum.
- Do not puncture, crush, or expose the old or new battery to extreme heat.
- If the old battery is swollen, do not attempt to remove it. Contact Shark customer service for guidance, as swollen batteries can be hazardous.
Step-by-Step Removal of the Old Battery
Now, let’s remove the old battery. The process is very similar for most Shark cordless stick vacuums.
- Power Down and Unplug: Ensure the vacuum is turned completely off. If it’s plugged into the charger, unplug the charger from the wall.
- Locate the Battery Compartment: On most models, the battery is housed in the main body of the vacuum, often near the handle or trigger.
- Remove the Screw(s): Find the screw that secures the battery cover. It’s often a single screw, but some models might have two. Use your Phillips screwdriver to carefully remove them and place them in your container.
- Open the Compartment: Gently slide or lift off the battery cover. You should now see the battery pack.
- Disconnect the Battery: The battery will be connected by a wiring harness with a plastic plug. Do not pull on the wires. Firmly grip the plastic connector itself and pull it straight apart to disconnect it.
- Remove the Battery Pack: Once unplugged, you can usually slide or lift the battery pack out of its compartment. It might be snug, so wiggle it gently if needed.
Dealing with a Stuck or Swollen Battery
If the battery won’t come out easily, double-check for any hidden screws or clips you might have missed. Refer to your manual. For a swollen battery, stop immediately. Do not force it. Place the vacuum in a safe, non-flammable area and contact Shark support.
Installing Your New Shark Battery
You’re halfway there! Installing the new battery is essentially the reverse of removal.
- Insert the New Battery: Carefully slide the new battery pack into the compartment, orienting it the same way the old one was seated.
- Reconnect the Harness: Take the plastic connector from the vacuum’s wiring and firmly push it onto the matching connector on the new battery. You should hear a soft click or feel it snap into place. Ensure it is fully seated.
- Replace the Cover: Put the battery cover back on, aligning it properly with the vacuum body.
- Secure the Screw(s): Retrieve your screw(s) and use the screwdriver to tighten them back down. Don’t overtighten, just make them snug.
Initial Charge and Calibration
Your new battery needs a proper first charge to perform its best. Don’t skip this step.
- Plug your vacuum’s charger directly into a wall outlet.
- Attach the charger to the vacuum and let it charge fully, without interruption. This can take up to 4-6 hours for a completely depleted battery.
- For optimal battery life, it’s a good idea to let it charge fully before the first use, even if it arrived with some charge.
- After the first charge, run the vacuum until it powers down to calibrate the battery meter. Then, charge it fully again.
Troubleshooting Common Issues
What if things don’t go perfectly? Here are solutions to common problems after a battery change.
Vacuum Won’t Turn On
- Double-check that the battery connector is fully clicked into place. This is the most common issue.
- Ensure the battery cover is securely fastened. Some models have a safety switch that won’t engage if the cover isn’t on.
- Verify that the new battery is charged. Try leaving it on the charger for a few hours.
Battery Drains Very Quickly
- You may need to complete a full charge/discharge/charge cycle to calibrate the battery’s internal meter.
- Make sure you purchased the correct voltage and capacity (Ah) battery. An incorrect battery will not perform properly.
- Check for blockages in the vacuum’s airflow (brushroll, filters, ducts). A clog makes the motor work harder, draining the battery faster.
Charger Light Blinks or Shows an Error
- Unplug the charger from the wall and the vacuum. Wait 60 seconds, then reconnect.
- Ensure the charging ports on both the vacuum and charger are clean and free of debris.
- The new battery might have a protection circuit that needs to be “woken up.” Leave it on the charger for a longer period (overnight).
Maximizing Your New Battery’s Lifespan
A good battery isn’t cheap, so you’ll want to make it last. Follow these simple habits:
- Avoid storing the vacuum in extreme temperatures (like a hot garage or freezing porch).
- Try not to run the battery down to 0% every single time. Partial discharges are easier on lithium-ion batteries.
- If you plan to store the vacuum for a month or longer, charge the battery to about 50% before putting it away.
- Keep the filters clean. Clean filters reduce strain on the motor, which conserves battery power.
- Use the correct power mode for the job. Use “Eco” or “Low” for hard floors and daily cleans, saving “Max” mode for deep carpet cleaning.
When to Call a Professional
While changing the battery is a DIY task for most, sometimes you need help. Consider professional assistance if:
- You discover significant corrosion or damage inside the battery compartment.
- You smell burning or see sparking during or after installation (unplug immediately!).
- The vacuum still doesn’t work after trying all troubleshooting steps with a confirmed-genuine battery.
- You are simply uncomfortable working with electronic components. There’s no shame in seeking help.
Frequently Asked Questions (FAQ)
