When Should I Replace The Batteries In A Roundup Wand?

Here are a few telltale signs your roundup wand needs new batteries.

Weak Stream

A sign that's easy to spot is when the stream coming out of your Roundup wand nozzle starts to weaken.

To check if this isn't a problem with the spray itself, Roundup advises priming your wand.

To do this, set the Roundup bottle on a table or elevated area and hold your wand below the bottle. Next, press on the wand's trigger lock for 30 seconds.

While doing this, make sure you're aiming the nozzle at a spot you're comfortable spraying Roundup on. This is to prevent accidental spraying on your plants.

If priming your Roundup wand doesn't help with the stream strength, then it's probably time to switch out the batteries.  

A weak stream isn't necessarily a bad thing, but if you want optimal results when using your wand, we recommend you switch out your batteries as soon as you spot this sign.

The Motor Isn't Running

Another thing to look out for is when you can't hear the motor running. 

To troubleshoot this issue, make sure to check if you've removed the protective strip. The motor won't run if this is still attached to your Roundup wand. Additionally, check if the trigger lock is disengaged.

If your Roundup wand isn't working after trying out these tips, it's time to get some new batteries. 

How To Replace Batteries In A Roundup Wand

1. Unscrew The Battery Compartment

You'll want to have a screwdriver ready for this step! Locate the battery compartment, which can be found at the base of the wand. Next, remove the two screws on the lid.

It's relatively easy to find the battery compartment regardless of whether you have the Sure Shot wand or Comfort wand, as they both have similar designs.

2. Take Out The Old Batteries

Remove the old batteries from your Roundup wand. Remember to correctly dispose of the old batteries as instructed by the manufacturer. 

The Environmental Protection Agency (EPA) advises consumers to find out if they can recycle used household batteries like the ones used in a Roundup wand.

Otherwise, it's probably okay to put the old AA batteries in the garbage (you can check with your local waste management facility).

3. Insert the New Batteries

Now that you've got the compartment open and removed the old batteries, it's time to insert the new batteries. Make sure to put them in the correct position as marked inside the battery compartment.

When replacing the batteries, always use a set of the same type. Using a mix of batteries can cause leakage and potentially damage your Roundup wand.

To prevent this from happening, don't mix different types of batteries, such as alkaline, carbon-zinc, or rechargeable batteries.

For better performance, it's best to use AA alkaline batteries for your Roundup wand, as recommended by the official Roundup website.

 4. Close the Battery Compartment

To finish up, secure the battery compartment lid with the two screws you removed earlier. Your Roundup wand is now ready for use again.

What's The Difference Between The Sure Shot Wand And Comfort Wand?

The Sure Shot Roundup wand and Comfort Roundup wand both serve the same purpose: to help you get rid of weeds.

Both models are used primarily around flowers, in vegetable gardens, and in areas with mulch. You can also use them to spray paved areas with cracks, like a driveway.

Here are a few features that tell them part:

Nozzle Attachment

The main difference between the two wands is that the Sure Shot wand is used for more precise weed-killing.

This Roundup wand model comes with an extra nozzle attachment that protects plants in your garden and landscaped beds, allowing you to hone in on weeds.

Hose Length

Another key difference between the two wands is the length of their hose. While both models have the ability to treat around 400 square feet, the Comfort wand's hose does not extend up to the same length as the Sure Shot wand.

The Sure Shot wand's hose can be extended to two feet, allowing for easier use while standing.

Color

As for their designs, they both share the same overall look. Both wands have trigger locks found at the handle and a battery compartment at the base. A quick way to tell them apart at first glance is through their color.

The Comfort wand comes in a light navy blue, while the Sure Shot wand comes in a bright lime green.

How To Store Roundup

Keep It Away From Children and Pets

You should store your Roundup weed killer in a place that is inaccessible to children and pets. Also, remember to place it away from sunlight and do not let the product freeze.

Remove The Batteries

According to the official Roundup website, it's best to remove the batteries before storing your Roundup wand. This is because the batteries might corrode inside the battery compartment when not in use for a long period of time.  

Battery corrosion isn't ideal, as it poses health concerns. The potassium hydroxide in alkaline batteries can cause chemical burns if not treated with care.

Corrosion can ruin both your batteries and your device. When this happens, you might have to replace your Roundup wand.  

To keep this from happening, remove batteries when they aren't in use and throw out batteries when they expire. 

How To Clean Battery Corrosion In A Roundup Wand

If battery corrosion does occur, and it doesn't look too severe, you can always try to save your Roundup wand by cleaning it. This can be done in a few simple steps with chemical-free items you may have at home.

1. Use Protection

Battery corrosion can be harmful. Remember to wear protective gear such as goggles, a face mask, and gloves before beginning the task. We also recommend you protect your work area by covering it with newspaper or an old cloth. 

2. Make a Paste

Pour a bit of baking soda on the battery acid, then use a cotton swab or toothbrush to dab the baking soda with lemon juice or vinegar until it forms a paste and begins to fizz.  

3. Scrub 

Once the fizzing subsides, you can scrub the paste to remove the corrosion. When you're happy with the results and ready to clean up, lightly dab the area with a wet cotton swab. 

Depending on the severity of the corrosion, repeat the process until you no longer see any white, crusty debris left from the battery leak. Once you're sure everything's dry, insert new batteries and test your Roundup wand to find out if it works.

In Summary 

Changing the batteries in your Roundup wand is a simple task. However, it's always good to be mindful of the kinds of batteries you use and how long you intend to use them, as they can impact the performance of your Roundup wand.

Prevention is always crucial in these situations, so remember to keep track of the expiration date of your batteries. Don't mix old and new batteries or different types of batteries. 

With these tips, your trusty Roundup wand should perform efficiently so you can zero in on those weeds in your garden.
