Description
4.8 Volt AA NiCad Pack Reverse Polarity Emergency Light Battery
The 4.8 Volt AA NiCad Pack Reverse Polarity is a rechargeable replacement battery commonly used in emergency lighting fixtures, exit signs, and combination emergency lighting units.
This battery pack contains four AA nickel-cadmium cells configured to produce 4.8 volts of reliable backup power. It includes a reverse polarity connector, which means the wiring orientation is opposite of standard polarity packs. Matching the polarity and connector type is critical when replacing emergency light batteries.
NiCd chemistry has long been used in emergency lighting systems because of its durability and ability to handle frequent charging cycles required for standby safety equipment.
When properly installed, this battery helps ensure emergency lights operate during power outages, helping buildings remain compliant with safety requirements.
