Gro-King recommends using a deep-cycle 12V Battery with the TRW-115 sprayer or the 12V Spray Kit. Many automotive and garden equipment batteries are designed to provide an initial “jolt” of current for the sole purpose of starting a motor. Deep-cycle batteries are manufactured to provide a steady source of current to actually operate small equipment for a substantial number of hours at a time. Using a deep-cycle battery will reduce the chances that spraying sessions will be interrupted/delayed by the need to re-charge.
Please allow 1 week from the date your order is confirmed by Gro-King, for Battery to ship. We will send you an email with shipping costs, after you place your order.
