The 5-position height adjustment lever makes it simple to set the right cutting height for your lawn. This handy feature along with self-propelled rear wheels with traction control gives you better maneuverability and ease of use while mowing different areas of your yard.

Battery & Charging

The Sun Joe AJ801E electric lawn mower comes equipped with a powerful 40V 5.0 AH lithium-ion battery. This gives the battery a longer lifespan and holds a charge longer compared to some similar electric mowers.

The battery voltage is on par with higher-end electric lawn mowers that gives it enough power to cut through moderately thick and tall grass.

On a full charge the battery can last up to 50 minutes of mowing time which is plenty for small to medium sized yards. The battery also charges quickly in 2 hours so you can recharge it in time to finish mowing your lawn in one session.

Performance

The Sun Joe AJ801E 13 inch cordless electric lawn mower performs very well across different grass types and conditions. It utilizes a 12-amp electric motor that delivers powerful spinning action from its 13-inch blades.

Cutting Efficiency

The AJ801E handles cutting short and tall grasses effectively. Its adjustable cutting height lets you quickly set the mower to cut grass from 2.1 to 3.2 inches in length. The mower delivers consistent cuts and doesn't bog down on even thick turf. Wet and dry grass conditions don't affect this mower's performance. Where gas mowers might struggle, the AJ801E powers through and leaves a level cut.

The AJ801E tackles inclines and hilly terrain thanks to its rear-wheel drive system and powerful electric motor. It can cut slopes up to 30 degrees without difficulty. The wheels maintain traction to move up steep hills without slowing or slipping, leaving a clean even cut in its wake.

Overall, the cutting efficiency and hill climbing ability of the Sun Joe AJ801E allow it to take on a wide variety of grass lengths and yard conditions. It's a robust electric mower suitable for standard yards as well as more challenging terrain.

Noise

The noise level produced by the Sun Joe AJ801E electric lawn mower is quieter than most comparably sized gas mowers. The manufacturer does not list a decibel rating for the mower. However, from customer reviews and firsthand experience, the lawn mower produces a low hum that allows you to hold a conversation near it without straining to hear.

The lack of a noisy gas motor contributes to the quieter operation. Instead, an electric 13-amp motor powers the spinning blades to cut grass. Some user reviews mention being pleasantly surprised at how quiet the mower is on their lawn. The noise level shouldn't disturb neighbors even with nearby homes.

As an electric lawn mower without a loud engine or engine exhaust, the Sun Joe AJ801E provides quieter operation for the user and those around them. While it produces a slight hum from the electric motor and spinning blades, it allows for conversation and listening to music while mowing your lawn.

Safety Features

The Sun Joe 13" electric lawn mower comes with important safety features to protect the user and prevent accidents.

• Safety switch - an onboard safety control disables blades automatically while mowing, if the user releases the operator presence control bar.

• Auto shut-off - the mower will automatically go into a low power state if left unattended for more than 5 seconds. Blades will stop within 3 seconds from lifting the safety control bar.

• Cord retainer - helps prevent accidental unplugging and keeps mowing cord away from the blades.

• Locking mower control - locks the folding joint when the lawn mower is in mowing position.

• Lightweight design - the 25lb electric mower is designed to be easily managed and push. Helping prevent strains or injuries from heavy lifting.

These built-in safety features give users peace of mind when operating the mower, ensuring safe and controlled use for all ages. The auto shut-off and safety switch prevent the blades from spinning out of control if the user lets go. While the locking joint and cord retainer prevent common accidents like unplugging or collapsing mid-mow.

Ease of Use

The Sun Joe AJ801E is designed with ease of use in mind. It features two control knobs for adjusting cutting height and an easy push button start/stop switch. With 13 inches wide, the width of cut makes it nimble to maneuver and easy to turn for trimming around trees, corners and other tight spots in the yard.

The variable cutting height adjustment offers 6 settings between 0.12-0.63 inches, allowing you to get the right trim for your lawn. Simply turn the adjustment knob and the wheels raise or lower for a smooth transition between heights. The knobs provide good control and stay in place each time you set them.

The handle is lightweight yet sturdy enough for moving the mower around. At only 25 pounds, the Sun Joe is extremely portable and designed for convenient and comfortable use, unlike heavier gas mowers. The intuitive controls, one-push button start and maneuverability make this an easy to use choice for any yard.

Price and Warranty

The Sun Joe AJ801E electric lawnmower retails for $199.99 at Amazon and other retailers (2022 prices). From a cost analysis standpoint, while the price tag may seem a bit high compared to some lower-end corded electric mowers, the AJ801E offers good value for a 4.5ah 40V rechargeable lithium-ion battery model.

The kit includes the mower, battery, charger, and mulching plug. So there are no extra accessories to purchase. The benefit of the AJ801E over a budget model is the convenience and freedom of movement from the cordless battery operation. It also typically runs for 45+ minutes on single charge, enough to mow up to 1/3 acre, making it suitable for the average residential yard. The larger 13 inch cutting width also offers improved efficiency over small 12 inch mowers.

As a battery model, consider factoring in the lifespan of the 2-3 year battery and cost of replacement in the total cost of ownership. Though with proper handling and storage, the AJ801E battery should hold a usable charge for many seasons before needing replacement. Still, an extra $50-80 for a replacement battery is realistic at some point.

In terms of included warranty, the AJ801E features a generous 2-year full warranty (10 years for motor). The typical industry standard is 1-year or less. Sun Joe also provides a 45-day money back guarantee with a satisfaction guarantee. This warranty coverage provides some confidence in the longevity and durability of the mower. Most issues with the mower should be covered and able to be addressed within the first 2-3 years of ownership. Replacement parts are usually readily available as well.

Overall, while not the cheapest option if price is the main consideration, the AJ801E provides good value for a powerful mid-level cordless electric mower.
