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.

4 most used battery types in 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
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
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
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
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
