Letting an unused battery self-discharge itself will damage it permanently in only a few months. Keep any battery not in service charged, without overcharging it with this charger. It will charge a battery to 100% state-of-charge, and then patiently wait, monitoring voltage periodically. When the battery’s self-discharge (Usually 10%-25% per month of storage, depending on the temperature) draws down the voltage enough, a brief charge cycle brings it back up to peak charge. This is calculated to keep the battery ready for use, but more importantly, will fight sulfation caused by undercharge. This handy charger will charge a battery from the front seat if the power socket remains hot when the key is off. If not, you can still use the clip-on leads.39.13Brand: Stanley Part Number: BC209 UPC: 897450002261
The Stanley Works was founded in 1843 in New Britain, Connecticut by Frederick T. Stanley to manufacture door hinges and bolts.. A few years later, in 1857, Frederick's cousin, Henry founded The Stanley Rule and Level Company. In 1910, S. Duncan Black and Alonzo G. Decker started their shop in Baltimore, Maryland, and were awarded a patent 6 years later for the world’s first portable power tool. In 2010 Stanley and Black & Decker combined to form Stanley Black & Decker, to deliver the tools and solutions that industrial companies, professionals, and consumers count on to be successful when it really matters.
