    I love the sprayer, but

    I love the sprayer, but honestly the battery problems are super lame. Why would anyone make a battery left in the sprayer too long so that it is impossible to recharge. I am on my third battery............terrible design.


    Hi, we are sorry you have experienced a problem with your Battery Backpack Sprayer. We recommend to charge the battery for 24 hours prior to spraying. The light on the charger should be solid green when ready for use. The battery should not be left on the unit as this will completely drain the battery even when the switch is in off mode. When your unit is not in use, please take off the battery and store it on the charging tender. If the problem persists, please call our Technical Customer Service Team a call at 800-444-3140 and reference this review, they will assist you with troubleshooting your sprayer and batteries to get this issue resolved. Thank you for your comments and for your business, we appreciate it. Chapin Customer Service
