Outdoor solar lights have become increasingly popular as an eco-friendly and cost-effective solution for illuminating outdoor spaces. At the heart of these devices are solar light batteries, which store energy generated by solar panels during the day and release it at night to power the lights. With a wide variety of chemistries and sizes available, choosing the right battery for your outdoor solar light can be a daunting task. 


Battery Chemistries:
Nickel-Cadmium (NiCd)
NiCd batteries have been a popular choice for outdoor solar lights due to their low cost and high cycle life. They can be charged and discharged repeatedly without significant loss of capacity. NiCd batteries perform well in extreme temperatures, making them suitable for a variety of climates. However, they suffer from the "memory effect," meaning their capacity can be reduced if they are not fully discharged before recharging. 


Nickel-Metal Hydride (NiMH)
NiMH batteries are an environmentally friendly alternative to NiCad batteries. They offer a higher energy density, meaning they can store more energy in a smaller space. Unlike NiCd batteries, they do not suffer from the memory effect, allowing for more flexible charging cycles. NiMH batteries have a shorter cycle life compared to NiCad batteries but are still suitable for most outdoor solar lighting applications. They also perform well in a wide range of temperatures.


Lithium Iron Phosphate (LiFePO4)
LiFePO4 batteries are a relatively new option for outdoor solar lights. They boast a high energy density, long cycle life, and excellent thermal stability. LiFePO4 batteries have a lower self-discharge rate than NiCad and NiMH batteries, making them ideal for long-term storage. While their upfront cost is higher than that of NiCad and NiMH batteries, their overall performance and lifespan make them a worthwhile investment for many outdoor solar lighting applications.


Battery Sizes:
We carry a wide range of battery sizes, suitable for various outdoor solar lighting needs. Here are some of the most popular sizes:
AA and AAA
AA and AAA batteries are the most common sizes for outdoor solar lights. They are readily available and come in both NiCd and NiMH chemistries. AA batteries have a higher capacity than AAA batteries, allowing for longer runtimes between charges.


1/3 AAA, 2/3 AAA and 2/3 AA
These smaller-sized batteries are ideal for compact solar lights or for devices with limited space for batteries. They come in both NiCd and NiMH chemistries.


80h, 20h and 40h NiMH Batteries
These high-capacity NiMH batteries are designed for heavy-duty applications, such as outdoor solar lighting systems that require extended runtimes or higher power output.


14430, 14500, 18500, 18650, 32650 and 32700
These cylindrical LiFePO4 batteries offer high energy density and long cycle life. They are ideal for outdoor solar lights that require high performance and long-lasting power.

 

Gama Sonic Battery Packs:

Gama Sonic battery packs provide a cost-effective solution for powering your outdoor solar lights. They are designed for easy installation and come in various capacities to suit different lighting systems.


NiMH Battery Packs
For those who prefer an environmentally friendly option, our Gama Sonic NiMH battery packs are a great choice. They offer higher energy density compared to NiCd battery packs, allowing for longer runtimes between charges. NiMH battery packs are also free from the memory effect, ensuring optimal charging cycles and extended battery life.

 

LiFePO4 Battery Packs
Our Gama Sonic LiFePO4 battery packs provide the ultimate in performance and longevity for your outdoor solar lighting system. With their high energy density, long cycle life, and excellent thermal stability, LiFePO4 battery packs are perfect for those seeking the best in outdoor solar lighting power solutions. While they come at a higher upfront cost, their overall performance and lifespan make them a valuable investment.


Selecting the Right Battery for Your Outdoor Solar Light:
When choosing a battery for your outdoor solar light, consider the following factors:
1.    Chemistry: Evaluate the pros and cons of each battery chemistry (NiCd, NiMH, and LiFePO4) and determine which one best suits your needs, budget, and environmental concerns.


2.    Size: Ensure the battery size is compatible with your solar light. Smaller-sized batteries, such as 1/3 AAA, 2/3 AAA, and 2/3 AA, may be ideal for compact solar lights, while larger sizes, such as 18650 and 32700, are suitable for high-performance lighting systems.


3.    Capacity: Choose a battery capacity that meets your desired runtime between charges. Higher-capacity batteries will provide longer runtimes but may be larger and heavier.


4.    Temperature Performance: If you live in an area with extreme temperatures, opt for a battery chemistry that performs well in those conditions. NiCad and NiMH batteries generally have good performance in a wide range of temperatures.


5.    Cycle Life: Consider the expected cycle life of the battery. While NiCad batteries have a longer cycle life than NiMH, LiFePO4 batteries boast the longest cycle life, making them ideal for long-term outdoor solar lighting applications.

 

Outdoor solar light batteries are a critical component of your solar lighting system. Understanding the various chemistries and sizes available will help you make an informed decision when selecting the right battery for your needs. Our wide selection of Nicd, NiMH, and LiFePO4 batteries, as well as replacement battery packs for Gama Sonic, ensures that you will find the perfect power solution for your outdoor solar lighting system.
