Methods to discover a battery’s Watt Hour (Wh) ranking
Producers are required to mark lithium-ion batteries with the watt-hour ranking, nevertheless it’s typically not clearly indicated on the packaging or on the ability financial institution itself—search for some tiny writing on one facet of the battery pack and also you’ll finally discover the Wh ranking. Don’t fear, we’ve achieved that for you in our suggestions under. You’ll be able to calculate the variety of watt-hours your battery gives if you already know the battery’s nominal voltage (V) and capability in ampere-hours (Ah), through the use of this calculation: Ah x V = Wh.
If you already know solely the battery’s milliampere hours (mAh), divide that quantity by 1,000 to get the ampere-hours (Ah). For instance, 1200mAh divided by 1,000 = 1.2Ah. Then multiply that quantity by the ability financial institution’s voltage.
