Power Up. Power your cordless iON tools the eco-friendly way with the 40-Volt EcoSharp PRO iBAT40XR lithium-ion battery. Compatible with all Snow Joe and Sun Joe iON models, the iBAT40XR features high capacity 5.0 Ah lithium-ion cells that deliver no-fade power for maximum job performance. Simply insert the EcoSharp PRO battery pack into your iON tool of choice and power up instantly without having to mess with gas, oil, pull-cords or tangled extension cords! Breathe easily and confidently while working with your iBAT40XR since this Energy Star-rated battery pack provides for cleaner, emission-free air during operation. Although run-times will vary depending on the tool used and the job performed, up to 65 minutes of whisper-quiet operation is a good approximation of what to expect from your iBAT40XR-powered tool. The fuel gauge indicator lights on the EcoSharp PRO will also let you easily monitor your battery's charge capacity while it is in use. When it is time to charge, simply slide the iBAT40XR into its dedicated iCHRG40 charger. Just like your cell-phone battery, the iBAT40XR has no memory effect, so there is no need to drain the battery or wait for full charge before use. The iBAT40XR holds its charge well in storage and will retain up to 65% charge for six months. Easy, convenient, reliable, and super-lightweight (only 2.6 lb.), the 40-Volt EcoSharp PRO iBAT40XR is the smart way to battery pack for your power trip. Model: IBAT40XR.
