The market is full of brands. What’s even worse is the number of reviews available. Our buying guide will help you make quick viable decisions while not compromising on anything.
Advantages of solar light batteries
Solar light batteries have several benefits. Check them below.
Money-saving – the cost of buying disposable batteries is high. However, solar light batteries eliminate the burden by enabling you to recharge them after use. Besides, they leverage sunlight hence no extra electricity bills for your garden lights.
Environment friendly – the beauty of renewable energy is that you get clean power all the time. While traditional alkaline batteries are one-use units, solar light batteries have long life cycles. Also, they do not contain harmful chemicals such as mercury and are recyclable.
Reliable – they supply significant power for your devices regardless of the season. If you want backup lighting in times of emergency, then the solar light battery is the right choice.
Portable energy – there is no doubt that solar light batteries are the most portable. They’re the best if you love outdoor activities such as camping. All you need is your panel and sunlight.
Easily accessible – hundreds of thousands of good solar light batteries are out there. It doesn’t take ages before you can have them.
Long-lasting – you get to reuse your batteries for months or even years before buying another set.
Features to consider before you buy solar light batteries
The market is full of solar light batteries. Finding the best solar light rechargeable batteries can be a daunting task. However, knowing what to look for in one is the best way to skip all the time-consuming process. Also, you don’t have to go through the trial and error path. We concentrated on the type, voltage, capacity, package, pre-charge, and certification while making our selection. All the mentioned features are crucial when looking for a solar light battery. More details below.
Type is the first place to start. Different types of solar batteries exist. Understand that one type is not identical to another. Acknowledging this fact is essential when making your decisions. You’ve seen NiMH and NiCD types on our list, and you probably have no idea what they are or mean. Maybe you did not pay attention to them, either. Well, the chemistry of each type is different. Nickel-metal hybrid batteries (NiMH) arrived the other day, and many consider them the best choice. They hold more electric charges as well as environmentally friendly. Mr. Batt Rechargeable AA Battery is an ideal example on our list. Nickel-cadmium (NiCD), on the other hand, has been around for a long time now. They’ve been and still are one of the best rechargeable batteries on the market. They’re lightweight and excellent for portable devices. Check out the EBL AA Rechargeable Batteries if you’re interested in them.
Have you ever asked yourself why we have batteries with different voltages? It’s because each device is unique in terms of how it functions and how much voltage it can accept. That’s why you must consider the voltage of a solar light battery that you want to buy. The first starting point is checking the voltage of your previous batteries. Replacing your battery with one that’s not compatible may result in a fried circuit board, or the device might never work.
Most solar light batteries have a voltage of between 1.2V and 1.5V. Avoid buying batteries that do not have the same voltage as what the manufacturer recommends.
While some might work right, they’ll eventually break your device in the long run. Some retailers do not specify the voltage of the batteries. Do not buy them before confirming. For instance, the Duracell Rechargeable AAA Batteries are excellent, but we’ve no idea about their voltage.
The battery’s capacity is an essential feature to consider. Again, just like the voltage, each device accepts different capacities. Some require batteries with high capacities, while others do not. It’s crucial to note that using a battery with extremely high capacity in a solar light or device that needs, maybe half of that, may result in breaking your device. Always check the mAh rating of your battery before making any replacement.
While you could use a battery with a slightly different capacity, the voltage should always be exact. The majority of the batteries have a capacity of between 600mAh and 1000mAh. However, some provide up to 1600mAh and beyond.
Solar light batteries come in different packages – a pack of 12 and 8 being the most common. While the packaging is not a critical feature, you cannot wish it away. Your needs should always lead when deciding on this element. There are a lot of factors to consider when looking at the packaging – pricing being one of them. Also, you want a pack that will be enough for you based on the number of solar lights in your garden. For instance, a pack of 4 won’t be sufficient for someone with several solar lights. A pack of 20, on the other hand, might be too much for someone looking to replace his remote-control batteries. However, it’s a good practice to always have an extra for backup, especially during rainy seasons. Check out the RELIGHTABLE Rechargeable Batteries if you’re looking for a large package and the Duracell Rechargeable AAA Batteries for two pairs only.
Pre-charge is a feature that comes into play if you’re for a battery to use on the go. Most of the solar light batteries come pre-charged. However, it’s quite hard to get one with a full charge. One reason a battery cannot come fully pre-charged is because of transportation safety. A good example is the Rechargeable AA Battery by Minetom. It comes with only 30% power. Tenergy Solla Rechargeable Battery, on the other hand, is ready to use out of the box. They come fully pre-charged and will last throughout the entire night. Other batteries, such as Mr. Batt Rechargeable AA Batteries come with 60% power. While you could use them immediately, it’s critical to always charge them to avoid altering their life cycle and performance.
The last aspect you want to check is certification. You must be aware by now that there are sub-standard batteries on the market. They not only underperform but also harmful to the environment and human health.
Finding out whether or not a brand is certified will help you evade unwanted problems. Although most of the solar light batteries are eco-friendly, it’s essential to confirm with the relevant bodies.
UL-certified or UL-listed batteries meet the specified nationally recognized standards for safety and won’t harm you. Also, they’re of high quality and efficient. An example of a certified battery is the Tenergy Solla Rechargeable Battery. Check the UL website for more information about battery certification.
Absolutely! One of the best things about these batteries is that they’re recyclable. It’s good to know that what you’re using can be useful later and not disposable to harm the environment. There are several sites that you can deliver them for recycling. Find out from the retailer or manufacturer about the same.
It’s pretty easy to prolong the life of a solar light battery. The first obvious thing to do is using it as per the specified directions. Avoid doing things that could shorten its life. For instance, do not reverse connect or short-circuit. While they use smart technology, avoid under-charging or over-charging. Also, do not mix different types. Lastly, try and use compatible chargers when recharging them.
Not all solar light batteries are compatible with any solar light or device. That’s the first mistake you want to avoid when making your purchase. We’ve already taken you through everything you need to know to avoid wasting money on the wrong batteries. Our buying guide should serve as a benchmark and help you spend the minimum time possible when shopping. The best solar light batteries are practical, efficient, and economical. We love our editor’s choice, Mr. Batt Rechargeable AA Batteries, because it has a high capacity, low self-discharge, and long life. Our premium pick, the Rechargeable AA Battery by Minetom, also has a high capacity, is versatile, recyclable, and UL listed. Finally, we picked the Duracell Rechargeable AAA Batteries as our best value because, regardless of it being a high-end battery – it’s affordable, long-lasting, and an all-purpose battery.
