If you've spent any time searching for a new, battery-powered lawn mower, you've likely been a bit overwhelmed by the sheer number of options, as many of the major power tool manufacturers are now making one. As far as the electric mower market is concerned, Ego devices are relatively well thought of. And since the brand's 2012 launch in the United States, Ego has built out its lineup of cordless electric mowers to include more than a dozen models that vary in size, function, and power output.

Each of those mowers is walk-behind by design, with Ego making claims that their grass cutters are capable of delivering gas power without all the noise and fuss. But as with any cordless electric mower, usage of an Ego device will be limited to its power supply. That fact alone makes the potential runtime provided by a battery every bit as important as its power output. Thus, the question becomes just how long an Ego battery lasts in its mowers. Unfortunately, the answer to that question varies depending on the Ego mower you're using and the battery you put inside it.

At present, Ego recommends a few different battery options for its mowers, ranging from 4Ah all the way up to 12Ah. While not every battery is recommended for every mower, the approximate runtime breakdown looks like this: 4Ah for 35 minutes, 5Ah up to 45 minutes, 6Ah at 55 minutes, 7.5Ah for 65 minutes, 10Ah at 85 minutes, and 12Ah providing up to 110 minutes of usage. 

Times can fluctuate depending on which Ego mower you are using, but you can also get a serious bump in runtime if you shell out for Ego's Peak Power mower, which offers two battery ports so you can double-up on the power supply. With the Peak Power device, a pair of 5Ah batteries can deliver up to 80 minutes of power, with two 7.5Ah power sources pushing the runtime to 120 minutes, and double 10Ah batteries running it up to 160 minutes. 

Ego's 21" Peak Power walk-behind mower can be purchased through several major retail outlets, including Lowe's, Ace Hardware, and Grainger. Still, the best price we've found for the Peak Power mower is through Amazon, where a kit that includes a mower, two 5.0Ah batteries, and a charger can currently be purchased for $669.91. Many of Ego's other battery-powered mowers can be purchased through the same retail outlets, among other, less prominent chains. Consult the device's Ego product page to determine availability.

As for Ego's batteries, they are also available through most of the same outlets where Ego mowers are sold. You should know, however, that even though those batteries compare favorably to other major brands, they tend to cost more. As with Ego mowers, prices for each make and model of battery will likely be a little more favorable through Amazon, where Ego operates its own storefront.
