Professional Pulse Load Accuracy: Basic testers measure voltage only, which can appear fine right until the battery fails. The patented microprocessor-controlled pulse load test places each battery under an actual working load and displays the true remaining charge on the color-coded LED bar within 2 to 3 seconds. Trusted Where Batteries Cant Fail: Constructed for security, medical, scientific, military, and industrial environments, and equally suitable for photographers, radio hobbyists, and collectors who require exact readings. Built with a durable design to withstand years of daily use. Carry Case Included: Your battery tester comes with a fitted carrying case for the truck, the gear bag, or the kitchen drawer. Solid brass, nickel-plated terminals maintain clean contact and consistent readings over the long term. Save Time, Save Batteries: Eliminate guesswork and stop discarding half-full batteries. Test the smoke alarm's 9V, the remotes AAs, and the key fobs coin cell in one go, restock the emergency kit before storm season, and never be unprepared again
