Simply configure the Kill A Watt, plug in the battery charger, and reference the device when it is done charging the battery. For the sake of example (and to compare it with the manual calculation technique we''re about to discuss in the next section), we charged a completely depleted 6.0Ah 40V lithium-ion battery while using the Kill A Watt meter.
Amount of charge the battery can store, determining how long it can power a device. Larger capacities mean longer run times. Common consumer batteries range from 2,000mAh to 100Ah or more for industrial use. Total energy the battery holds, calculated as capacity in Ah multiplied by voltage. Important for understanding total energy in the battery.
This applies to lithium metal batteries (disposable) and lithium ion batteries (rechargeable). This is usually stated on the battery itself (see Image 1). If not, you can calculate it as Volts x amp hours (Ah). example 1: an 11.1 volt 4,400 mAh battery – first divide the mAh rating by 1,000 to get the Ah rating – 4,400/1,000 – 4.4ah.
Suppose you have a corded drill with a power consumption of 800 watts, and you use it continuously for one hour. To calculate the energy consumption, multiply the wattage by the duration in hours: Energy consumption (in kilowatt-hours) = (wattage / 1,000) * duration (in hours) Using the given example, the energy consumption would be:
To measure the electricity usage accurately, it is essential to consider the drill's intermittent usage patterns during a typical hour. For instance, if you use the drill for just 15 minutes and then leave it idle for 45 minutes, the energy consumption will be lower compared to continuous usage.
For my Makita 14.4V drill I used a Turnigy 1300mAh 4S (14.8V) LiPo pack that measures 74mmx 34mm x 33mm and it fit the empty battery casing perfectly. You don't want the battery to use all of the available space as you'll need a bit of room for the wiring and low voltage alarm, Now it's time to do some wiring! Take your power tool casing apart.
In contrast, the cordless drill will draw power from its battery, which typically ranges from 12 to 20 volts. Assuming the battery has a capacity of 2 Ah (amp hours), the drill may consume around 24 watt-hours (12 volts * 2 Ah) to 40 watt-hours (20 volts * 2 Ah) per hour of usage.

2- Enter the battery depth of discharge (DoD): Battery Depth of discharge refers to the percentage of a battery that has been discharged relative to the overall capacity of the battery. For example, if your battery is discharged at 80%, enter 80. 3- Enter the charge current and select the unit type from the list. It''ll be mentioned on your charger.
To determine the electricity consumption of a corded drill, we need to consider two key factors: the drill''s wattage and the duration of its use. Wattage refers to the amount of power consumed by the tool, while the duration of use indicates the length of time the drill is actively being used.
Cordless drill power consumption can be estimated by measuring the current draw and voltage of the drill''s battery when in use. To do this, you will need a multimeter capable of measuring both AC and DC voltages and currents. First, fully charge the drill''s battery and then measure the voltage of the battery when disconnected from the drill.
Measure the inside of the casing to determine how large a LiPo battery pack you can fit inside that closely matches the power tool voltage rating. For my Makita 14.4V drill I used a Turnigy 1300mAh 4S (14.8V) LiPo pack that measures 74mmx 34mm x 33mm and it fit the empty battery casing perfectly.
