4 Most used Battery Types in Solar Flood lights and

What you Need To Know about Each of them

www.ledsolarfloodlights.com

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

Ni-Cd (Nickel-Cadmium) battery

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

Ni-Cd advantages

• Longer life charge and discharge cycles

• Lower self discharge rate• More tolerance against

overheating unlike Ni-MH

Ni-Cd disadvantages

• Low battery capacity• Memory effect• Toxic cadmium

Ni-MH (Nickel – Metal Hydride) battery

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

Ni-MH advantages

• Higher capacity• No memory effect• Environment friendly• LSD Ni-MH

Ni-MH disadvantages

• High self discharge rate• Over-discharge

LiFePO4 (Lithium iron phosphate) battery

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

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

LiFePO4 disadvantages

• More expensive than Lead-acid batteries

• Lower energy density• Low discharge rate• Lower temperatures impacts

battery

Lead-acid battery

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

Lead-acid advantages

• Cheaper and easy to make• Low self-discharge• High power• Performs well in low and high

temperatures

Lead-acid disadvantages

• Heavy and less durable• Low specific energy• Slower charging• Sulfation• Unfriendly for environment
