The BLIFE series rechargeable battery is a reliable and long-lasting power source designed primarily for use in exit signs and emergency lighting. It uses Lithium Iron Phosphate (LiFePO₄) technology, which makes it safer and more stable than regular lithium batteries. This battery can be charged and used over 2,000 times, providing dependable power when it’s needed most. With a capacity of 4000mAh and a 6.4V output, it delivers steady performance with low energy loss over time. Its standard size also makes it compatible with other devices and applications that require the same battery type. Optional heater blanket allows the battery to be installed in cold weather emergency lighting. The heater blanket ensures the battery stays at an optional operating temperature.
We strongly recommend keeping the existing battery lead for re-attachment.
