Cordless Electric Push Mowers: Introduction
If you have a larger lawn than a corded mower can reach, but you still want all of the benefits of an electric mower, then you still have the option of buying a cordless electric push mower. The downsides to using a cordless mower are recharging time and the limited amount of mowing time per charge. Rechargeable batteries can take several hours to recharge. You need to assess if the length of mowing time per charge is going to be sufficient for your lawn care needs.
On average a 24-volt mower's charge will allow it to run for up to one-and-a-half hours. This is enough time to mow an area of up to one third of an acre. A 36-volt mower's charge will enable it to run for about three hours and mow an area of approximately one half of an acre. The onboard batteries also make cordless electric push mowers heavier so they can require a little extra strength and effort to push uphill. They are not self propelled so if you have a lawn that has steep hills you may want something with a little less weight or more power. However, if you have a small to medium sized lawn that is fairly flat then the cordless electric push mower may be just what you are looking for.
