Power up. Power your cordless iON tools the eco-friendly way with the 40-volt EcoSharp™ iBAT40-RM lithium-ion battery. Compatible with all Snow Joe® and Sun Joe® iON models, the iBAT40-RM features high capacity 4.0 Ah lithium-ion cells that deliver no-fade power for maximum job performance. Simply insert the EcoSharp™ 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 iBAT40-RM 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 50 minutes of whisper-quiet operation is a good approximation of what to expect from your iBAT40-RM-powered tool. The fuel gauge indicator lights on the EcoSharp™ 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 iBAT40-RM into its dedicated iCHRG40 charger. Just like your cell-phone battery, the iBAT40-RM has no memory effect, so there is no need to drain the battery or wait for full charge before use. The iBAT40-RM 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 lbs!), the 40-volt EcoSharp™ iBAT40-RM is the smart way to battery pack for your power trip.
