You might be asking yourself, how long does a Black and Decker weed eater battery last? Well, Black and Decker weed eaters run 40 minutes or less per charge under average conditions.

The Black and Decker line of weed eaters is designed to take care of all your lawn maintenance needs, from trimming hedges to taking care of weeds to clearing out brush on your property.

Let’s see in detail about the battery longevity along with some pro tips.

How Long Does A Black And Decker Weed Eater Battery Last On One Charge?

The answer to your question is going to depend on your use conditions. If you’re cutting thick grass or have a large yard, you may use up more of your battery than if you were trimming around a fence in a small garden.

We found that Black and Decker weed eaters run 40 minutes or less per charge under average conditions. Here is a comment from a happy Black and Decker user-

“Really love this weed eater; it works really well. I am only using it for residential properties, like homes the 1500-2000 sq ft size with weed eating the perimeter of each home, driveway and sidewalks, and patios with two batteries. The two batteries I have were the 2.0 ah, which I get about 30-40 minutes weed-eating with each battery.”

How Long Does A Black And Decker Battery Last on Average?

Most Black & Decker weed eaters, or string trimmers as they are also known, contain a lithium-ion power source. This means that they are able to hold a charge for up to 18 months before needing a full replacement.

If you don’t use your trimmer often, you may need to charge it every six months to keep its memory intact.

Also, a weak or damaged charger can affect how well your device charges.

It is important that you use only the original cord included with your weed whacker when charging because other cords may not output enough current for an effective charge.

How to Make Your Black and Decker Weed Eater Battery Last Longer?

Weed eaters from Black & Decker are a popular choice among DIY enthusiasts. The strong engines make light work of trimming grass, but that comes at a cost to your batteries.

Over time, you will notice that your Black & Decker weed eater battery no longer has as much charge as it used to.

So how can you maximize its performance so that you don’t have to replace your weed eater every year or two? Here are some tips on how to extend your Black and Decker weed eater battery life.

1. Keep Your Weed Eater Charged at All Times

The number one way to maximize your Black & Decker weed eater battery life is to keep it charged. If you have a spare charger, charge your weed eater whenever you’re not using it so that you don’t have to worry about running out of juice when you need it most.

Alternatively, if you can afford to purchase an extra charger, consider buying a second one so that you can keep one in storage while charging another in your garage or shed.

2. Store Your Weed Eater in a Cool, Dry Place

The second most important thing you can do to extend your Black & Decker weed eater battery life is to store it in a cool, dry place. Extreme heat or cold will degrade your Weed Eater’s performance over time.

If you live in an area where temperatures regularly exceed 90 degrees Fahrenheit, consider investing in a small cooling fan for your shed or garage so that you can keep your Weed Eater cool when not in use.

3. Keep Your Weed Eater Out of Direct Sunlight

It’s tempting to leave your weed eater outside so that you can quickly grab it when you need to use it, but sunlight will degrade your Black & Decker weed eater battery over time.

If possible, store your weed eater in a dark shed or garage where sunlight can’t reach it. Alternatively, invest in a UV-resistant cover to protect your weed eater from sun damage during storage.

4. Never Overcharge Your Weed Eater Battery

Overcharging your Black & Decker weed eater battery will reduce its lifespan significantly. When you notice that your weed eater is fully charged, unplug it from its charger to prevent overcharging.

If you’re not going to use your weed eater for a while, remove its batteries completely to prevent accidental overcharging.

How Often Should I Charge My Weed Eater Batteries?

A lot of homeowners ask, how often should I charge my weed eater batteries? If you use your trimmer several times a week, be sure to take a look at them on a regular basis.

A good rule of thumb is to recharge them after every three uses or so. While you can’t overcharge a Black & Decker battery, there are some side effects if they aren’t charged properly as well.
