Your Companion's battery just died mid-shift and you can't wait three weeks for a generic swap from a marketplace. This is the LEADER 7.4V, 5000mAh battery that was in the unit when it left the factory. Drop it in, charge overnight, and you're back online by morning. It's the exact spec your SC530 or SC530PRO was built around — no guesswork, no compatibility headaches. We keep these on the shelf because we know a dead battery is the last thing you need when the device is already doing the heavy lifting for you. Add to cart and it ships as soon as it's packed
