The Yuasa Yucel Y4-6 is a 6V 4AH maintenance-free, rechargeable sealed lead acid battery that is commonly used in alarm systems, emergency lighting and other stand-by power applications requiring a high-rate discharge.
Featuring AGM (Absorbed Glass Matt) technology, the Y4-6 retains the maximum number of electrolytes in its cells and the valve regulating design ensures safe, low pressure venting of excess gas.
