Will the RG1000 work in cold winter weather?

Cold weather makes jump starting much more difficult, as not only do batteries lose their effectiveness, but turning your engine over is tougher due to stiff belts, thicker oil, etc. To optimize starting, we recommend bringing your RG1000 to room temperature before boosting. If this is not possible, you may find that the first attempt at jump starting will produce a weak output (turn over slow or not at all). This is normal, as when a lithium battery is cold, output is reduced. One advantage of lithium batteries is that they warm up fast from use. Keep attempting to start your vehicle (crank for no more than 5 seconds per time) as each attempt will warm up the RG1000 battery and allow more cranking power.
