{"title":"Power Tool \u0026 Cordless","description":"\u003cp\u003eA dead battery has a way of stopping a job cold. The drill quits halfway through hanging a door. The vacuum won't hold a charge long enough to finish the room. The yard tool dies with the lawn half-cut. Usually the tool itself is fine, and it's the pack underneath that's worn out. We stock, test, and replace power tool batteries here in Willoughby, OH, along with batteries for cordless vacuums, handheld appliances, and the other battery-powered equipment that's become part of how you get things done.\u003c\/p\u003e\n\n\u003cp\u003eBefore you replace anything, it helps to know what actually failed. Sometimes a pack that seems dead just needs a real charge, or the charger is the thing that's gone bad. Sometimes the cells are genuinely finished. We'll test it for free and tell you which it is, even the times it turns out you don't need to buy anything from us. And depending on the pack, the right answer is a fresh battery or \u003ca href=\"\/pages\/battery-rebuilding\"\u003erebuilding the one you already own\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003ch2\u003ePower Tool Battery Replacement: Chemistries and Equipment\u003c\/h2\u003e\n\n\u003cp\u003ePower tool and cordless tool batteries come down to three chemistries that cover most of what crosses our counter:\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLithium-ion (Li-ion)\u003c\/strong\u003e — the modern standard in most cordless drivers, drills, and newer Dyson vacuums.

Drill packs, Dyson battery replacement, an old NiCad that won't take a charge: chances are we've done it. We've spent 36 years in this one Willoughby shop getting the chemistry right and the connection clean, on everything from a contractor's daily-driver drill to a vacuum somebody leans on every weekend. Bring the tool, bring the dead pack, and we'll troubleshoot it together.\u003c\/p\u003e\n\n\u003cp\u003eCome in, ask your questions, and get a straight answer about what your equipment actually needs.
