Our take on the Harbor Breeze Portfolio Rechargeable Phosphate Solar Battery 18500 2 Pack

A two-pack of 18500-size rechargeable LiFePO4 cells rated 1000 mAh at 3.2 V, sold for solar lights and small outdoor gear. LiFePO4 chemistry holds up better to heat and repeated charging than the NiMH and lithium-ion cells many solar fixtures ship with, and it does not suffer the fire risk of lithium-ion. The trade-off is lower energy density than a lithium-ion 18500, so runtime per charge is shorter. It suits owners replacing tired cells in solar path lights, garden lamps and small 3.2 V devices.

Best forReplacing dead cells in solar path and garden lightsHot outdoor fixtures where lithium-ion is riskySmall 3.2 V devices that take 18500 cells
Pros
  • LiFePO4 chemistry is stable and heat tolerant
  • Rated for many more charge cycles than NiMH
  • Two cells per pack covers a pair of lights
  • Nominal 3.2 V matches common solar light circuits
  • No lithium-ion fire risk in outdoor fixtures
Cons
  • 1000 mAh is modest for an 18500 cell
  • Lower energy density than lithium-ion rivals
  • Only 3.2 W, so small devices only
  • Needs a charger set for 3.2 V LiFePO4, not a standard li-ion one

Questions and answers

Will these work in my solar path lights?
Only if the fixture takes 18500 cells and is built for 3.2 V LiFePO4. Check the old cell's size and voltage first. Many solar lights use AA or AAA NiMH instead.
How does LiFePO4 compare with lithium-ion here?
LiFePO4 is safer in heat and lasts more cycles, but 1000 mAh is less capacity than a typical lithium-ion 18500. Expect shorter runtime per charge.
Can I charge them in a normal li-ion charger?
No. Use a charger with a LiFePO4 setting at 3.2 V. A standard 3.6/3.7 V lithium-ion charger can overcharge them.
What is in the pack?
Two 18500 LiFePO4 cells, 1000 mAh, 3.2 V each. No charger is included.
Are they worth it over cheaper NiMH cells?
If your lights run hot or you are tired of replacing NiMH cells every year, the longer cycle life makes them the better long-term pick. For cool indoor use, NiMH is fine.
Where is the Harbor Breeze Portfolio Rechargeable Phosphate Solar Battery 18500 2 Pack cheapest?
At Lowe's, for $19.98, as of our latest check.
