We have received many inquiries regarding the various sizes of rechargeable batteries for solar lights. There are a few reasons why manufacturers choose one size over the other. They are as follows:
So, we will address each of these points above in further detail.
Item 1. A smaller battery will give the manufacturer the option to create a solar light that is smaller than what it would be had a larger rechargeable battery been used. Smaller batteries can store the same amount of energy capacity (mAh, or milliAmp hours) for each night’s use. For instance, a 600 mAh 1.2 Volt rechargeable battery can come in either a AA or AAA size. However, if you compare it to water flowing in a river, the AAA size is going to be a smaller river width, while AA batteries represent a larger river and thus more water can flow through. They will both flow for the same amount of time, only the AA will be able to provide more current (water, in our river example above) than its AAA counterpart over the same amount of time. The force of the water (ie: Voltage) is the same for both, only the AA will be able to provide more current and thus, a larger or demanding LED component (think, more current will allow for a brighter LED to be used). In the image above, two Lithium batteries with the same specifications are set side by side. However, the black battery is what is considered a 2/3 AA, while the grey battery is the more common AA size. The smaller battery will give the same output, but for a less powerful LED demand. The smaller battery is compact, but it is sufficient enough for a lower output illumination device (in this case, it was used in a solar spot light with 1 LED that was purchased from a big box store.) The advantage of the smaller battery is that it allows for a smaller solar light. The biggest disadvantage is that the replacements for these batteries are difficult to find, and when found, relatively expensive compared to their AA counterparts.
Item 2. The battery chemistry will play a factor in the design in a number of different ways. For one, the amount of electrical potential (Voltage) that a battery can provide will depend on the chemical makeup of the battery. AA Lithium ion batteries typically have a Voltage rating of 3.2 Volts; whereas the same size NiMH (Nickel Metal Hydride) or NiCd (Nickel Cadmium) will have a Voltage rating of 1.2 Volts. So, using a Lithium battery in a NiMH light will burn out the LEDs of the NiMH light almost instantly. The LED will be brighter than ever, but that moment in the spot light, so to speak, will end in a matter of seconds. So it is recommended to not use Lithium batteries in either NiMH or NiCd battery lights. Using a Lithium battery will give the manufacturer the option of increasing the LED load capacity (thus a brighter light), but will ultimately cost the customer more in the long run as replacement batteries for Lithium lights are more expensive.
Item 3. Since AA and AAA battery sizes are more common (AA moreso than AAA) than fractional sizes (such as the 2/3 AA in the photo above), costs for production have been set to allow for the best available pricing for customers worldwide. Being that AA batteries have been around since 1907, their production infrastructure has had plenty of time to develop and take hold on the battery market. There are square 9 Volt and larger Lead Acid rechargeable batteries on the market for use in solar lights. However, since they are odd shaped for the purpose of streamlining solar light designs, they are less commonly used and ultimately will cost more (also for the fact that they hold more energy) and are weighty.
Item 4. There are a number of chemical components that make up solar light rechargeable batteries. The primary distinguishing components are Nickel Cadmium (NiCd), Nickel Metal Hydride (NiMH), Lithium Ion and Lead Acid. Developed in 1899 by Swedish inventor Waldemar Jungner, it would take NiCd batteries over 4 decades to hit the market for commercial consumption. At the time, the competitor for NiCd batteries was the Lead Acid battery. However, due to the latter’s dimension restrictions as a small and portable battery, NiCd took hold and was widely used as a consumer-ready battery. Not until 1989 (with subsequent years of development) was the NiMH battery introduced to the market as an alternative to its Cadmium-based battery. NiMH rechargeables are capable of a better performance over the long term (for solar garden lights, typical lifespan of both chemistries is about 2 years). NiMH rechargeables also use a mild toxicity chemistry as opposed to the heavy metal toxicity of Cadmium (which makes up about 18% of the battery). NiMH batteries are capable (although it is recommended to recycle them whenever possible) of being thrown out in the trash. Whereas NiCd batteries must be recycled/disposed of in the proper facility. Lithium Ion batteries are taking their hold on the market due to their unsurpassed performance compared to other chemistries. But their setbacks are their disposal at the end of their lifecycle (recycling costs more than mining, so they may likely be thrown in the trash), higher cost of the battery for the consumer and transportation restrictions.
So, with all the considerations above, you will be better able to find the right solar light for your specific project. All of the battery chemistries have proven to have working track records, but each have their own pros and cons. Just be sure that the specifications you are looking for match what your solar lights came with when you first purchased them. If you are still not sure about the correct solar light batteries to use, check out our previous posts on the subject. There is much to know, but it is all worthwhile as solar lighting has great potential when it comes to illuminating your home, garden and office exteriors.

Just bought the solar garden gnome, and I have only two words…. Love it! I was looking for a gnome for my garden, and saw that these guys have one that is solar. I wasn’t sure how he would look in the garden or how the solar would work, but I absolutely love my little gnome. The mushroom lights up at night, so I am able to see him when the sun goes down. I put him next to some succulent plants in my garden, and he fits right in.
Now he will need a friend, so it’s off to see what other gnomes they have in their store.
Thanks Your Solar Link for my new addition!
Just like chameleons Stone Solar Lights completely camouflage with existing landscapes and look like any other ordinary garden rock.
Also known as Solar Rock Lights, they can be used to mark landscape hazards, such as steps or a large boulder that could be a hazard in the dark. They are a good alternative to cast light on shrubbery and low hedges, and to mark pathways.
These Solar Spot Lights are a suitable addition for rock gardens, xeriscape landscaping, or for anywhere that solar garden lights would fit into your garden. Models vary from a nice, light brownish green to standard gray colors for blending perfectly into your existing landscape design.
Aside from being completely powered by the sun, they have no wiring and are fast and easy to install. With its flat base, each stone solar spot light can be placed it on the ground, giving you the option to move it to various locations as needed.
And because they are solar powered, they save money on your energy bills in the long run.
They come equipped with integrated solar panels that are durable in all weather conditions. An on/off switch is located at the base of each light, allowing you the option of saving battery charge for special occasions or during times when you wish to simply have the light off. When they are in the on position, an integrated photoresistor turns the lights on at sunset and off at sunrise.
You will be surprised by the amount of light that stone solar spot lights cast onto your garden. Just place your rock light where sunlight reaches in your exterior spaces, and the integrated solar panel will do the rest. Solar rock lights are capable to get light into areas of your garden where no electrical supply is available. They can give up to 10 hours of light when dark, depending on the amount of sunlight they receive during the day. The LED bulbs never burn out, and the rechargeable Nickel Cadmium AA battery is comes installed are ready to go right out of the box. They are water and corrosion resistant, as well as being completely safe to use around pets and children.
You can check these and other solar lights at www.yoursolarlink.com/solar-spot-lights, where they are sold at reduced prices with no hidden charges and free shipping.
Solar spot lights like this one rely on energy from the sun to charge their batteries and provide light throughout the night. This means that there is no need to tap into the electrical grid for these lights to operate. The solar spot lights will work consistently, even if the whole neighborhood is dealing with a power outage.
Solar spot lights efficiently use energy stored in the rechargeable batteries when it uses multiple LEDs. In this case, 4 ultra-bright LEDs provide bright and effective lighting.
These Ultra Bright Solar Spot Lights can be used to light up many different features of a landscape at night. You can create an interesting focus by putting light on an appealing tree or a flowerpot. Another practical application would be to increase visibility along the exterior walls of a home, driveway or a walkway.
All solar spot light models are adjustable in their positioning. It could be directed up, down or forward, and at different angles around the post. All you have to do is to turn the wing-nut to secure its position.
Even on cloudy days your solar lights will charge, but it is always best to choose the sunniest location for your spotlight to get the most charge from the sun. Typically, the charge will last throughout the night. Your solar light will also turn on and off automatically every day.
Solar Spot Lights can also be used as a low voltage substitution to your existing outdoor lighting. At www.yoursolarlink.com, you can check out our Solar Calculator for your energy bill savings when you decide to replace your existing electrical spot lights with solar spot lights.
In the video below you can see it in a night setting. The 4 LED bulbs create an effective and sufficient directional beam.
The more LEDs a solar light has (it can be as much as 6, 10 or more LEDs), the sooner the rechargeable batteries will get used up for the night. This means that you could get fewer hours of a more intense light. But for this particular solar spot light, a perfect balance is achieved. The design gives the brightest light output with the longest duration throughout the night. And its LED bulbs never burn out.
These solar spot lights is corrosion and water resistant, so it’s safe to leave outside during all weather conditions. Each light is 6.5 by 7 inches square and 18 inches tall. They also come equipped with 3 Nickel Cadmium AA batteries and are ready to go right out of the box.
In the vocabulary of our modern world, the term “organic gardening” has become widely popular in gardening magazines, books, on the World Wide Web and in everyday conversations.
While growing without chemicals is trendy now, it has been around since ancient times. It was the only way to farm. After all, chemical fertilizers weren’t even a possibility until the 1840’s.
So, what exactly is organic gardening? And how is it beneficial to us?

In plain words, organic gardens don’t get fertilized with synthetics; only animal or vegetable fertilizers are used.
Natural pest control methods are used, as opposed to industrial insecticides. In other words only natural substances and beneficial insects are used to ward off pests instead of spraying with potentially harmful commercial chemical substances.
Tatiana Starines has been enjoying organic gardening for over 70 years.
And just look at the results!

6 major benefits of organic gardening:
1. The harmful and toxic chemicals that we spray on our produce also seep into the ground, thus affecting insects that are beneficial. These chemicals also find their way into the air, waterways, sewers, lakes and streams. Organic gardeners create a mini “eco-system” that will maintain a healthy balance of soil and contribute to the health of our planet by not putting long-lasting, toxic chemicals into the air, soil and watershed. This makes organic gardening beneficial for everyone.
2. Organic gardeners contribute to preserving diversity. The loss of a large variety of species (biodiversity) is one of the most pressing environmental concerns. The good news is that many organic farmers and gardeners have been collecting and preserving seeds, and growing remarkable varieties for decades.
3. It is no-brainer that the natural health of the soil will produce healthy fruits and vegetables for your table. Organically-grown food is more nutritious than food grown using conventional methods. In humans, healthy and balanced nourishment increases strength of the immune system and minimizes the risks of potentially deadly diseases.
4. There is evidence of physical and emotional human benefits with organic gardening. “muscle-power” rather than “machine-power” burns more calories. You definitely will be in great shape and stress-free (horticultural therapy), when you spend quality time in your garden.
5. Organic gardening greatly reduces your exposure to pesticides, which have been linked to many severe health problems.
6. Growing your own healthy produce saves your household money in the long run.
