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

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
