- Li-Ion (Lithium-ion) batteries for emergency lights
Sanforce offers Li-ion batteries exclusively designed for emergency lights. Because of their high trickle charge capacity, Li-ion batteries work efficiently even at temperatures as high as 60C. Since these battery packs can handle and deliver higher power to appliances, the Li-ion batteries are ideal for power tools that demand big capacity with lighter weight.
- Ni-Mh (Nickel-Metal-Hydride) batteries for emergency lights
Nickel-Metal-Hydride (Ni Mh) emergency lighting battery packs are an earth-friendly option. This rechargeable battery provides useable voltage during the entire discharge, allowing you to experience peak performance every time you use the battery. These battery packs which can be fitted with a remote also, deliver consistent power to emergency lighting sources when needed.
- Ni-Cd (Nickel-Cadmium Battery) emergency lighting battery packs
Nickel-Cadmium (NiCd or NiCad) batteries are suitable for emergency lighting equipment as per IEC 60598-2-22. It has high energy storage density, lighter and more compact than lead-acid- batteries. Because of such characteristics, it is preferred as a backup power source for emergency lighting when size and weight are the key selection factors. Along with that, these batteries have a lower self-discharge rate and long cycle life than Ni-Mh batteries.
Despite the differences, all of these three battery types are capable of converting and storing electricity and powering the emergency lights when the mains supply fails. As a major component of emergency lights, you should choose battery packs based on your specific requirements and conditions. Along with that, the life of any battery packs is shorter than the emergency power driver and as such, should be replaced every three years. Though emergency lights come equipped with battery packs, you can order batteries separately also.
