SHURflo SRS-600 ProPack Rechargeable Backpack Sprayer is shipped with a fully charged battery but may require charging prior to use. It is recommended to charge 24 hrs before first use. A fully depleted battery will take approximately 14 hours to fully charge. Always charge battery for 8 hours after each use to prevent it from reaching a low state.
