Buying Guide: How to Choose the Right Battery for Your Dewalt Lawn Mower
When I first started looking at batteries for my Dewalt lawn mower, I was a bit overwhelmed by all the numbers and acronyms. It turns out, it’s not as complicated as it seems once you know what to look for. The main things you need to pay attention to are voltage, amp-hours, and the battery type. Getting this right means your mower will have the power to get the job done and the stamina to finish your lawn without quitting halfway through.
First, let’s talk about voltage. Dewalt mowers typically use either 20V or 60V FlexVolt batteries. The 20V batteries are common and work well for smaller to medium-sized lawns. The 60V FlexVolt batteries are the real powerhouses, giving your mower more torque and longer runtimes, which is perfect for thicker grass or larger properties. The cool part about the FlexVolt system is that a 60V battery can also be used on your 20V tools, so it’s a versatile choice if you’re already invested in the Dewalt ecosystem.
Next up is the Amp-Hour (Ah) rating. Think of this as the gas tank size. A higher Ah rating means a longer runtime. For a mower, you don’t want to skimp here. I’d recommend starting with at least a 5.0Ah battery. If you have a larger yard, stepping up to a 9.0Ah or even a 12.0Ah battery will save you from having to stop and swap batteries mid-mow. It’s the difference between finishing the lawn in one go or having to take a break to recharge.
Finally, consider the battery technology itself. Dewalt’s PowerStack line is a newer option that uses pouch cells stacked vertically. These batteries are more compact and can deliver higher peak power, which is great for maintaining consistent blade speed in tough mowing conditions. While they might be a bit more of an investment, the performance boost can be worth it. When choosing from the 8 best batteries for Dewalt lawn mower types, always match the voltage your mower requires and then go for the highest Ah rating your budget allows for the longest possible runtime.
FAQ
Can I use a 20V battery on a Dewalt 60V mower?
No, you cannot. A 60V Dewalt mower is specifically designed to operate with the higher voltage and power output of a 60V FlexVolt battery. Using a 20V battery will not provide enough power to start or run the mower. However, the reverse is a key feature: 60V FlexVolt batteries are designed to be backward compatible and can be used on 20V tools.
How long does a Dewalt mower battery typically last?
On a single charge, the runtime varies greatly depending on the grass height, thickness, and your mower’s battery. A 5.0Ah battery might last for 30-45 minutes in average conditions, while a 9.0Ah or 12.0Ah battery can easily push past an hour. In terms of overall lifespan, you can expect a good Dewalt battery to last for several years, typically handling 500 to 1000 full charge cycles before you notice a significant drop in performance.
Is it okay to leave my Dewalt battery on the charger after it’s full?
While Dewalt chargers are designed with safeguards to prevent severe overcharging, it’s still a good habit not to leave batteries on the charger for extended periods, like days on end. The best practice is to remove it once the indicator light shows a full charge. For storage, I keep my batteries in a cool, dry place, charged to about 40-60% if I won’t be using them for a while.
What does the FlexVolt label mean on my battery?
FlexVolt is Dewalt’s innovative technology that allows a single battery to automatically switch its voltage output. A FlexVolt battery can operate as a high-power 60V battery in compatible tools like lawn mowers and as a standard 20V/18V battery in your other Dewalt tools. This gives you maximum power and runtime without needing two separate battery systems.
Why is my mower’s battery life shorter than it used to be?
This is a normal sign of battery aging. All rechargeable batteries lose capacity over time and through repeated charge cycles. Factors like frequent deep discharges, exposure to extreme heat or cold, and long-term storage while fully charged or completely empty can accelerate this process. If you’re looking at the 8 best batteries for Dewalt lawn mower types as a replacement, you’re likely seeing the natural end of your old battery’s useful life.
Can I use a higher Ah battery than what came with my mower?
Absolutely, and I often recommend it. Using a higher Amp-hour (Ah) battery, like swapping a 5.0Ah for a 9.0Ah, is completely safe and will simply give your mower a longer runtime. The mower only draws the power it needs, so a higher capacity battery just means it will take longer to deplete. It’s one of the easiest ways to extend your mowing sessions without stopping.
