4 most used battery types in LED solar flood lights

  1. 1. 4 Most used Battery Types in Solar Flood lights and What you Need To Know about Each of them www.ledsolarfloodlights.com
  2. 2. The most popular battery types used in LED solar flood lights • Nickel group batteries – Ni-Cd (Nickel-Cadmium) – Ni-MH (Nickel – Metal Hydride) • Lithium group batteries – LiFePO4 (Lithium iron phosphate) • Lead-acid batteries – Valve-regulated Lead-acid battery
  3. 3. Ni-Cd (Nickel-Cadmium) battery
  4. 4. Ni-Cd (Nickel-Cadmium) battery • Ni-Cd batteries are primarily used for smaller solar flood lights that has lower power and level of brightness • Ni-Cd batteries are mostly used in packs of more than 3 in different solar flood lights • The power in voltage produced by both Ni-Cd and Ni-MH batteries are practically the same
  5. 5. Ni-Cd advantages • Longer life charge and discharge cycles • Lower self discharge rate • More tolerance against overheating unlike Ni-MH
  6. 6. Ni-Cd disadvantages • Low battery capacity • Memory effect • Toxic cadmium
  7. 7. Ni-MH (Nickel – Metal Hydride) battery
  8. 8. Ni-MH (Nickel – Metal Hydride) battery • Ni-MH batteries are the most popular battery type for lower brightness LED solar flood lights, and are used in lot more floodlights than Ni-Cd batteries • Ni-MH batteries have almost three time higher capacity than Ni-Cd batteries
  9. 9. Ni-MH advantages • • • • Higher capacity No memory effect Environment friendly LSD Ni-MH
  10. 10. Ni-MH disadvantages • High self discharge rate • Over-discharge
  11. 11. LiFePO4 (Lithium iron phosphate) battery
  12. 12. LiFePO4 (Lithium iron phosphate) battery • LiFePO4 or Lithium iron phosphate batteries are used on higher-end LED solar flood lights • Currently used by few manufacturers • Has got many advantages over competitors
  13. 13. LiFePO4 advantages • • • • • • • • Long cycle life Long service life Constant discharge voltage Safe and stable Wide temperature range Fast charging Light, flexible and small form factor Environment friendly
  14. 14. LiFePO4 disadvantages • More expensive than Lead-acid batteries • Lower energy density • Low discharge rate • Lower temperatures impacts battery
  15. 15. Lead-acid battery
  16. 16. Lead-acid battery • Lead-acid batteries are used in large and powerful outdoor solar floodlights • Lead-acid battery type used in solar flood lights is VRLA (valve-regulated lead-acid) • VRLA batteries can be operated and installed in any direction without danger of liquids spilling out of the battery, and they are maintenance free
  17. 17. Lead-acid advantages • • • • Cheaper and easy to make Low self-discharge High power Performs well in low and high temperatures
  18. 18. Lead-acid disadvantages • • • • • Heavy and less durable Low specific energy Slower charging Sulfation Unfriendly for environment
