There are few more popular types of batteries used in Solar Flood lights - Ni-Cd, Ni-MH, LiFePO4, Lead-acid. Each of these battery types are suited for certain flood light type. In this presentation I have explained, what each of those batteries are, listed all their advantages and disadvantages and pointed out which battery type is suited for what type of LED solar flood lights.

  • 1. 4 Most used Battery Types in Solar Flood lights and What you Need To Know about Each of them www.ledsolarfloodlights.com
  • 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. Ni-Cd (Nickel-Cadmium) battery
  • 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. Ni-Cd advantages • Longer life charge and discharge cycles • Lower self discharge rate • More tolerance against overheating unlike Ni-MH
  • 6. Ni-Cd disadvantages • Low battery capacity • Memory effect • Toxic cadmium
  • 7. Ni-MH (Nickel – Metal Hydride) battery
  • 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. Ni-MH advantages • • • • Higher capacity No memory effect Environment friendly LSD Ni-MH
  • 10. Ni-MH disadvantages • High self discharge rate • Over-discharge
  • 11. LiFePO4 (Lithium iron phosphate) battery
  • 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. 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. LiFePO4 disadvantages • More expensive than Lead-acid batteries • Lower energy density • Low discharge rate • Lower temperatures impacts battery
  • 15. Lead-acid battery
  • 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. Lead-acid advantages • • • • Cheaper and easy to make Low self-discharge High power Performs well in low and high temperatures
  • 18. Lead-acid disadvantages • • • • • Heavy and less durable Low specific energy Slower charging Sulfation Unfriendly for environment
