![]() It’s important to look at the whole package: the battery in conjunction with the motor and the tool being used, along with the ergonomics and overall engineering. Some manufacturers are using peak voltage to figure Watt Hours. This will also affect the Watt-Hour label on the battery. – i.e., a 58-volt battery is not better than a 56 volt. Nominal (actual working) voltage is 18, 46, 54 and 72 volts. So, that is the number they typically use on the label – i.e., Pro 80V or 40V MAX. For example, maximum initial battery voltage (measured without a workload on a fully charged battery) is 20, 56, 60, and 80 volts. Here in the U.S., the brands are allowed to “fudge” the voltage label. One more little marketing detail on voltage. I’m not aware that any of the chargers have built-in battery cycling, cell balancing and or battery peaking tech. Most cells are wrapped to pull heat away from the cell. The Lithium batteries and chargers used in these kits have overload and overcharging tech built-in so they don’t explode or melt down your workbench. Brushless systems now have speed/load sensors built-in that increase the torque/speed when the load is greater and reduce the power/speed when the load is light – saving battery life. These are marketing terms and the engineering is not specific to that one tool or brand. Smart Cut Technology, ARC Lithium Design, MaxLithium, Brushless Motors and Smart Lithium Battery Tech. If you have more than one tool using the same battery the savings over gas-powered will show up quicker. What does that mean? If the battery-powered unit cost $100 more than the cost of a comparable gas-powered unit it will start paying for itself around the 100-hour mark. Typically a hedge trimmer or string trimmer costs just 2 cents per hour to operate-which is about 95 cents per hour less than a comparable gas unit. So, the initial cost is higher but when you look at total operating costs, not just purchase price cordless electric starts to make real sense. Once you have a product or two with batteries you can buy just the “bare tool” without the extra batteries and charger. Remember, the cost of the initial product includes the battery and charger so that is like buying the item and 3 or more years of gas, oil, and filters all up front. If you are trying to rotate them too fast through the charger thermal overload protection will keep them from overheating and ruining the battery. Many of the systems now come with 1 hour quick chargers so you can be using one battery and have another one charging quickly. Most of the current reliable brands have switched to the high-efficiency brushless motors and a few have gone to the patented CORE system. The efficiency of the electric motor will also determine how long a battery lasts. Watt Hour is not always listed in the specs but is printed on the battery itself. Watt Hour is the easiest way to compare different batteries and battery system. But a 40 volt 5 AH battery will give you about the same power available as an 80 volt 2.5 AH. For example, a 5 AH battery will last twice as long as a 2.5 AH for the same voltage. Battery capacity in amp-hours (AH) and the battery voltage (V or Volts) together gives you the power available. A 36-40 system can be just as powerful as a 56-80 volt system. Don’t know me?

Some of the battery systems I will list will even work in your cordless hand tools! ![]() It’s really advantageous when you can have just two or three of the same batteries that will work in all your cordless yard tools. You end up spending $150-$200 extra for each tool just for batteries. It doesn’t make a lot of economic sense for you to buy the best of each the way these articles want you to do, for example, an EGO string Trimmer, a Troy-Bilt leaf blower and a DeWalt chainsaw. It’s now time to take a serious look at what’s available and what is the best for you. I see hundreds of articles expounding the virtues of this cordless mower and that cordless string trimmer or blower but almost no reviews that include the complete line of tools each brand’s battery covers. In fact cordless electric yard tools now outsell the gas equivalents.
