Snapper XD SXDWM82K 82V Cordless 21-Inch Walk-Behind Lawn Mower is powered using 2Ah and 4Ah Briggs & Stratton 82V lithium ion batteries. Kit comes with two 2Ah batteries and fast charger, providing up to 45 minutes of operation. Easy use and storage, 21 inch mowing width, efficient design, brushless electric motor, large wheels, 7 height positions etc. are reasons why Snapper XD SXDWM82K is one of the best rated cordless walk-behind lawn mowers.
Snapper XD cordless lawn mower is powered using Briggs & Stratton 82V lithium ion batteries. First of all, 82V is maximum voltage of these batteries when fully charged (20 cells, 4.1V per cell), with nominal voltage being 72V (20 cells, 3.6V per cell). Either way, these are some serious voltages, and they can cause some serious damage and injuries.
Unit is equipped with a strong, 1200 W high-efficient electric brushless motor and a 'Load Sensing Technology' which adjust the motor power and hence battery discharge rate.
This is very important since two 2Ah batteries ideally store 288 Wh (2 batteries x 2Ah x 72V) and 1200W motor at full power will fully discharge these batteries in ~14.4 minutes.
So, with Load Sensing Technology, operating time with these two batteries is advertised to be up to 45 minutes, which is 3x more than without such technology.
Anyway, this math shows that there are no two exactly the same gardens, with the same conditions - and on those conditions depend actual operating time. So, in real life, one can expect 25-30 minutes of operation using these two batteries.
Snapper XD SXDWM82K 82V Cordless 21-Inch Walk-Behind Lawn Mower has 21 inch steel mowing deck, with 3-in-1 design - It can mulch (with mulching plug installed), bag (bag mounted on the rear of the mower) or side discharge (with side discharge chute installed) grass clippings. Lawn mower comes with large 1.6 bushel (2.1 cubic ft) grass bag.
Mowing height (7 possible positions) is set using single lever. Wheels are large and help the mower to easily cover large areas - front wheels are 8 inches (20.3 cm) in diameter, while rear wheels are 10 inches (25.4 cm) in diameter.
In order to save space when not in use, handle is foldable and the unit is designed to be stored vertically, with small storage footprint. Although the mower is stable when in upright position, don't let the kids or pets play around it - if it is hit with enough force, it can tumble over and damage or injure something or somebody.
During operation, unit is very quiet, especially when compared with the gas powered units. Also, since it lacks power cord, it is very easy to maneuver around. On the other hand, its operating time is limited and depends on the available batteries, sharpness of the blades and lawn condition.
Fast charger comes with the lawn mower and can be used to charge 2 Ah and 4 Ah batteries at rates:
- 2 Ah battery: 50% charge in 13 minutes, 100% charge in 30 minutes,
- 4 Ah batteries: 50% charge in 25 minutes, 100% charge in 60 minutes.
Smart battery charger sense the battery condition and charge the battery accordingly. It is NOT recommended to keep the battery in the charger indefinitely.
When delivered, batteries are not fully charged - before the first use, charge them fully.
Note: there is no lawn mower that can cut wet grass with no issues at all ... been there, done that :)
Mower comes with 5-year limited warranty and batteries with 2-year limited warranty.

Snapper XD BSB4AH82 82V 4.0 Ah lithium ion batteries for Snapper XD 82V cordless tools store double the amount of energy when compared with 2.0 Ah batteries.
Initially, they do increase the purchasing price, but after that, bare tools do come rather cheap.
