Best Solar Light Batteries – Rechargeable Alternatives

In 2020, outdoor lighting solutions include a dizzying array of options, from multicolored and smart lighting to the lowly incandescent bulb. As simple as the choice was 10 or 15 years ago,
you would be forgiven if you now had difficulty choosing how to best light your yard, home exterior, or garden. Because of the environmental factors that the socially-conscious among us must take into consideration, many have chosen solar powered lighting. That choice necessitates the purchase of rechargeable solar light batteries. Obviously, given the option, you’d choose the best of the best.

Rechargeable solar-powered light batteries allow you to run those lights that don’t exert an additional drain on the energy grid. Simply put, these batteries collect solar energy from an attached solar panel during the day and expend that energy by illuminating a bulb you’ve placed outside your home in your yard or garden. They don’t require any alternative forms of charging or electricity nor do they have to be plugged into a wall socket if they’re attached to a working solar panel.

What you’re looking for in a rechargeable solar-powered light battery will remain pretty much constant. However, there are some differences to keep in mind. Use your judgment to determine what you need and which solutions would best serve those needs. We’ll identify some features you should keep in mind at the bottom of this article after we list our recommendations

Not limited to the usual solutions, creativity can turn what appears to be a relatively benign and boring topic, rechargeable batteries and the lights they power, into a versatile lighting experience. Amazon user reviews suggest these items have been used for everything from saving on energy bills to making life easier for a late-night walk down the hallway. Read on below to find out what the best solar rechargeable batteries are for 2020.

Features To Consider

When deciding on which solar-powered light bulb battery to buy, you’ll want to keep a few category features in mind. Of course, a standing caveat is to always consider what you’re using the product for and how much luminosity you need. If you need to keep a large room fully illuminated all day, your needs will differ from a person looking to keep a small motion-sensing night-light on over a bedroom door. You’ll also need to consider the features of the light inside which these batteries are installed.

Ease of Installation

As most people are not electricians or engineers, the typical consumer is looking for a product that is easy to install and maintain. Luckily for that consumer, all of the products included on this list are “plug and play.” If you’re especially worried about this feature though, you may wish to choose a product that offers free lifetime technical support, as having someone you can call about any issues can make a world of difference when dealing with a problem.


Some of these products are going to end up inside lights that are attached to the wall of your home, garage, shed, or even barn. As a result, they need to secure properly to the wall without causing any unnecessary damage or unsightly marks.


Solar indoor light bulbs spend their time inside, where the weather isn’t an issue. But the solar panels that power them (much like solar generators) are attached to walls of houses and garages in all sorts of weather and climates. Rain, hail, sleet, snow, and high winds are all possibilities, depending on where you live. The solar light panels you choose, and the batteries that power the lights they’re attached to, must be able to withstand all of these. These products accomplish the task via the use of durable construction and workmanship and a tempered glass coating over the top of the solar panels. Keep in mind that this glass should be cleaned regularly, in order to ensure that the solar panels are soaking up as many of the sun’s rays as they’re capable of. Without that maintenance, these rechargeable batteries won’t charge while the sun is up, defeating the purpose of purchasing them in the first place


This is not a product you want to fail on you as it’s likely to happen at the worst possible moment. Isn’t that how it always is with batteries of any kind? Make sure to choose one that’s made well, ensuring consistent reliability. The last thing you want is to include one of these in your light before you go out for the night only to find out the next evening that the thing wasn’t working at all and you’re now left to serpentine your way down the hall in the dead of night and the pitch black.

Brightness and Color

This one’s a no-brainer. Some bulbs are brighter than others. Some bulbs are different shades of white than others. You want a light that’s bright enough to illuminate your setting without searing the pupils out of anyone in a two-mile radius. It’s a balancing act and all of the batteries on this list will fully power whatever type of solar bulb you’ve chosen.

The Two Major Types of Solar Light Batteries

The Two Major Types of Solar Light Batteries

Generally speaking, you’ll be choosing between two different types of rechargeable batteries for solar lights: Nickel-Cadmium (Ni-Cd) and Nickel-Metal Hydride (Ni-Mh). The two have slightly different features and benefits and will affect how you use, charge, and dispose of these batteries.

Nickel-Cadmium batteries can generally handle a wide variety of chargers and are more versatile than their metal-hydride cousins. Ni-Mh batteries, on the other hand, are great for applications that call for low-amperage, lengthy, and continuous use. So any solar lights that are on for an extended period of time, in other words. In these situations, Ni-Mh batteries will outlast their competitors. (Looking for a guide on how to fix solar lights to keep them running longer? Check out our guide on solar light repair!)

How Do You Charge Solar Light Batteries

When correctly installed in a properly configured solar light, these rechargeable batteries should discharge at night when the lights come on, and recharge automatically during the day when the sun is shining.

Ideally, you won’t have to think about the process. It will just happen naturally. However, due to the imperfect nature of even the most carefully calibrated batteries, they will slowly lose their capacity to hold a charge over time. The batteries will eventually have to be replaced.

How Long Do Solar Light Batteries Last?

This depends entirely on how you use them. For the most part, rechargeable solar batteries last longer if they are allowed to charge fully, and discharge slowly and continuously. So they’ll typically last longer in applications that call for continuous lighting over long periods of time with low-wattage bulbs.

Consider Adding Solar Light Batteries To A Gift

Consider Adding Solar Light Batteries To A Gift

Because of their extreme versatility, indoor and outdoor solar light bulbs make perfect gifts, especially for a person with the environment and energy efficiency on his or her mind. Also, the dimly lit nature of some rural properties makes them perfect candidates for the addition of convenient additional lighting.

They should especially be considered in areas frequented by children and in areas where additional security is a must-have. After all, there’s no use having a security camera if it’s so dark that the camera can’t pick up any images. A substantial body of research shows that thieves and prowlers avoid brightly lit targets, preferring to skulk around in the dead of night. So, odds are, if you add one of these indoor solar light bulbs to your property, hooligans will bypass your floodlit rooms and seek out someplace more inviting.

All of this means that indoor and outdoor solar lights (like our favorite solar lanterns) make for fantastic gifts, but only if they can actually be turned on! Add some batteries to that gift of solar light and you’ll allow the recipient to cross one item off their post-Christmas to-do list.

Be Creative

You don’t only need to use these rechargeable solar light batteries only on solar lights. Anywhere one needs a small or large amount of power could create utility for one of these little guys. While indoor and outdoor solar-powered bulbs make great uses for these batteries, so do remote controls and video-game controllers. You can even use them as backup power for solar Christmas lights if you choose.

Be Secure

As mentioned previously, prowlers and thieves hate the light. The brighter your yard and home, the less likely that someone sinister will make a target of it. Do yourself a favor and keep your property brightly lit with some solar powered outdoor lights. While you could certainly go with a product specifically designed for security, any light that’s bright enough will do the trick if it’s installed properly. Consider grabbing one of the more aesthetically pleasing lights, installing it creatively, popping in one of these rechargeable batteries and get kudos for your environmental friendliness and secure your home in one fell swoop.


Gone are the days when installing lighting inside your home required proximity to a wall and outlet. Solar powered indoor bulbs, and the rechargeable solar light batteries that power them, make that problem a thing of the past and do so while putting very little strain on your budget. As is clear from the foregoing, we strongly recommend the Westinghouse AA Solar Batteries. Its blend of features and value is the perfect combination for the vast majority of consumers and the positive Amazon reviews are proof of that. If you want to save a little bit of money though, you can’t go wrong with the RELIGHTABLE AA NiCd. At just under $15 for a fully functional pack of twenty batteries, you’ll hardly notice the cost. You’ll definitely notice the tremendous utility you get from the product though, as there’s hardly anything on the market as useful as these solar light batteries.
