From portable devices to essential household appliances, we rely on batteries for almost every single device we use nowadays, many of which require batteries. Now, batteries aren’t exactly expensive but seeing how most households burn through them over time, it certainly couldn’t hurt to cut back on the cost of batteries if we can. We do that with the help of rechargeable batteries which for the most part, are just as efficient as the single-charge models if not more.
One very important thing to point out on the subject of rechargeable batteries is their increased potency, mainly their capacity to hold their charge for longer periods of time. Not only that but the fact that they can be reused makes them a lot more environmentally-friendly than disposable batteries. This is because batteries contain hazardous chemicals that once released in the environment, they take decades to dissipate. By reducing the number of batteries present in the environment at all times, you thus reduce their overall impact.
All things considered, rechargeable batteries should definitely be seen as a long-term investment more than anything else, not just for their relative cleanliness but also for their improved charge. Even so, some rechargeable batteries are much better than others, which is why you want to learn as much about them as possible before making a purchase. To maybe give you a helping hand on that matter, I’ve put together a list of the ten best rechargeable batteries I could find at this point in time.

Rechargeable Batteries Buying Guide
Nobody can deny the sheer versatility of rechargeable batteries and how they can fit the part of their common alkaline counterparts. It wouldn’t be too much of a stretch to say that they have entirely replaced traditional batteries in many modern households and it is easy to see why. For the most part, they are more reliable, more sturdily built, hold a bigger charge, and will perform a lot better when used with high-drain devices like flashlights.
Now, because of their construction, some of these rechargeable batteries may be a pain to look after, especially in regards to the hazardous chemicals used in their making and the high maintenance efforts required. So to give you a better idea of what they’re all about, we should perhaps understand what makes a good rechargeable battery and what features to look for when buying some.
Types of Rechargeable Batteries
Rechargeable batteries mainly come in three essential categories: Nickel-Cadmium based, Nickel-Metal Hydride, and Lithium-Ion. Despite their construction, they pretty much all serve the same purpose, although some are definitely more reliable than others. The biggest feat of a rechargeable battery is its capacity to maintain its charge over long periods of time, which is where you want to start off when judging a specific model. You have to understand that in principle, the lithium-ion batteries are without a doubt the longest lasting batteries, but that they cannot all be expected to perform with high-power devices. Here is what you need to know about each type of rechargeable battery:
Nickel-Cadmium Batteries – These rechargeable batteries are by far the most common, which is why you will find them on sale in pretty much any supermarket across the country. Even though they have a reasonably long charge hold, they absolutely have to be recharged while they still have energy to spare. Waiting until they completely dry out is bound to severely reduce their reliability or to even incapacitate them completely. As such, these batteries are perfect for outdoor devices like lamps and flashlights.
Nickel-Metal Hydride Batteries – With these type of batteries, you get the type of charge that many household and electronic gadgets use. Given their household usage, they rarely contain hazardous chemicals, thus reducing the risks of accidental leaks. They also have a low discharge rate, which is the reason why they also cost a lot more money than nickel-cadmium batteries, a price tag that reflects their increased reliability. Due to their build, they are mostly used by people who require regular battery backup support, mostly gadget-oriented professions.
Lithium-Ion Batteries – Many modern devices employ lithium-ion batteries, mostly because of their long charge hold and easy maintenance. These batteries can be found in most popular smartphones, tablets, laptops, or pretty much any other portable device. Their popularity is owed to the fact that they hold 2-3 volts for every energy cell, which adds to their long-term dependability. One downside with these type of batteries is the bulky size; but then again, you should expect high-power batteries to be a bit bigger.
What To Consider
Battery Life – The first thing to consider when buying a rechargeable battery is how long you can realistically expect it to deliver a constant stream of energy with a single charge. In this respect, make sure to read up on the battery’s mAh capacity and whether it can hold a charge that is slightly bigger than what the label says. This refers to the milliamp/hour rating, a unit of measure for how much power a battery can hold at a time. In that regard, the bigger the mAh capacity, the longer the battery can be expected to last after being charged.
Compatibility – With battery life out of the way, you then have to figure out if a battery is compatible with whatever devices you plan to use it with and whether it will deliver the type of charge you require. I say this because high-drain devices like outdoor flashlights tend to drain batteries pretty fast, especially if they are not designed with the intended purpose of giving out a strong output over short periods of time. As such, you have to really think about what you’re going to use them for, in the sense that low-discharge batteries with a smaller output are a lot better for remote controls and alarm clocks.
Charger – You also have to bear in mind that rechargeable batteries require a charger that you employ to bring them to full capacity. This charger can differ in size, shape, and form between manufacturers, and yet they all tend to meet the same operational standards. They can also accommodate between two and eight batteries depending on the model and how big your budget is, not to mention how they can also charge differently sized batteries at the same time. Interestingly enough, some of these modern chargers even have wall plug or USB ports to choose from, which furthers their versatility overall.
Budget – It shouldn’t come as too much of a surprise to find out that reputable brands can sometimes charge double for their rechargeable batteries. This is because of the intricate manufacturing process and the technologies used in the making of the batteries. Given the supercell developments and the low-discharge reliability of some high-end models, you can expect the price tag to go anywhere between 15 to 30 dollars or more. It also has to be said that you shouldn’t be cheap when it comes to rechargeable batteries because the initial couple of bucks you spend on the acquisition will definitely be repaid by the several hundreds of extra recharge cycles these top-shelf batteries are capable of.
Reviews – With rechargeable batteries, one should always consider what people are saying and whether they have reached other people’s expectations. While this might be true with the purchase of various electronic devices, there is also a personal preference element to them, which cannot be quantified in practical terms. With batteries, on the other hand, it isn’t so much about personal preference as it is about proven reliability. Considering that most people have no reason to lie, you would do best to gauge what the market has to offer based on reviews above all else.
