hello to all. A few years ago I bought the ez sprayer backpack battery operated sprayer. For the life of me, I cannot find my charger. :( I also cannot find online anywhere to buy a new one. Can someone help me? I also wonder, as hubby says that maybe the battery isn't even good anymore. I wonder about that - it's 3-4 years old, hardly used. tia I love the sprayer and miss it
