At the end of our research, after spending hours evaluating how different types of batteries perform in various conditions, how well, and for how long, we agreed that 100% PeakPower AA Rechargeable 2300mAh NiMH Batteries are the best rechargeable batteries you can find on the market. If you’re searching for reliable, long-lasting batteries for any of your electrical appliances, you have just found them.

It is impossible to picture our everyday life without batteries. As a power source, they can be found anywhere – from our toothbrushes, mobile phones, and kid’s toys to work tools and medical equipment. In the past, disposable batteries were the only ones available, and they weren’t the most reliable source of power; they would often leak and because of that last for only short periods of time before dying.

Thankfully, reusable batteries have taken over. Not only can you count on their much longer life and you can rely on them to not develop leaks, but these batteries are also often the less expensive option in the long run. Besides that, if you’re someone who cares deeply about the environment and downsizing the waste you produce, there is no reason for you not to switch from disposable to rechargeable batteries.

Types of Rechargeable Batteries

As you can imagine, since there are countless appliances that run on reusable batteries there are also just as many different sorts of this power source. Rechargeable batteries vary in shape and size depending on the use and application they are intended for. The wide variety of these products may seem confusing, but there are a few main characteristics you should keep in mind when looking for the best pack of rechargeable batteries for you.

Before presenting you the top picks we decided on, we will explain the most often used classification of rechargeable batteries. Hopefully, after reading this, you will be able to decide on the type you like the best, depending on your preferences and needs.

Lithium-Ion (LI-Ion) Batteries

Are you looking for the perfect energy-to-weight ratio in a battery for use with objects such as laptops or mobile phones? If so, lithium-ion rechargeable batteries are the best choice for you. Lithium-ion batteries are known for their light weight, and because of that they are often used in portable electronics. But they are also becoming popular as power sources for electronic vehicles and even space applications.

What is remarkable is that the light weight has no negative effect on the energy of the battery; it stays on a high level of efficiency. The mechanism of this type of batteries relies on negative lithium ions repositioning from the negative electrode to the positive one, while during charging the opposite happens. Other important characteristics of Li-ion batteries are their high energy, low maintenance requirements, and low levels of self-discharge, features which make lithium-ion batteries the battery type with the highest potential.

Advantages of the Kratax 9V 850mAh Rechargeable Li-ion Battery and Charger
  • Powerful
    Even with the lighter weight of this product compared to that of some disposable batteries, that doesn’t mean a lower power output. Actually, when considering the 850mAh capacity and the possibility of recharging the battery about 500 times, one Li-ion battery has more power than 1500 individual alkaline ones.
  • Reduced Self-Discharge
    Self-discharge of batteries occurs when chemical reactions happen inside the battery that reduce the charge even though the battery is not actually being used. Thankfully, that happens in Li-ion batteries less than it does in NiMh and alkaline batteries when stored in the same environment.
  • No Memory-Effect
    Another situation that is characteristic for some batteries is memory effect. This term is used to describe how the battery loses its maximum capacity if it’s constantly charged after not being completely discharged first. With this type of batteries, though, you don’t need to worry about your battery’s capacity going down with time since there’s no memory effect.
Bottom line

Who says that batteries have to be big and heavy in order to produce enough power for your electric devices? Lithium-ion batteries are not only compact and practical but will also keep your appliances working at their best for long periods of time.

What to Look for in a Good Rechargeable Batteries

In the end, which rechargeable batteries you choose will depend on your individual preferences. The kind that works well for one device may not be that great for another. This is the reason you should take many different things into consideration before finally deciding on the battery for you. With that being said, we present you with the most important criteria to keep in mind when making a decision about buying rechargeable batteries.

  • Device Compatibility
    Probably the most important thing you will want to check is the size of batteries that will fit into the device you’re buying the batteries for. Chances are you have come across labels such as AAA, AA, C, or D on batteries or electronic devices. These letters are used to mark the size of batteries needed, with AAA being the smallest and D the largest. Rechargeable batteries often come only in sizes AAA or AA, which makes it even easier for you to pick out the ones compatible with your devices.
  • Battery Life
    Of course, when buying any battery you will want to know how much energy it holds. The way to figure that out is by looking for the mAh label on the battery itself, which stands for “milliamp hour”, a rating of amount of energy. Obviously, the higher that number is, the longer your device will be powered by the battery. Also, consider that not all your electrical devices need high-energy batteries – a remote controller and child’s toys can probably be powered by batteries with a shorter life than those for cameras or flashlights.
  • Charger
    With rechargeable batteries, a charger is a necessity so that you can reuse the same battery many times. It’s best to look for chargers that have the ability to charge multiple batteries at once, and it’s even better if it can charge two different types of rechargeable batteries at the same time. Some other features to look for when choosing a charger are LED lights that indicate if charging is done or not, or smart features like the charger automatically switching itself off after the batteries are full.
  • Price
    One thing that differentiates rechargeable from disposable batteries is the price. At first glance, it seems like reusable ones will cost you more money, but you should take a closer look at the long-term effect. The number of times you can reuse one rechargeable battery actually adds up to more available power than that of a single, disposable battery. This is why you should be prepared to invest a larger amount of money in rechargeable batteries, but keep in mind that this is money well spent considering that reusable batteries will pay for themselves after a couple of charges.
  • Environmental Impact
    As we have mentioned a few times, all reusable batteries are better than disposable ones when it comes to how environmentally friendly they are. But even when looking only at rechargeable kinds, some are more “green” than others. For example, since nickel-cadmium batteries contain cadmium, which is a heavy metal, they are more toxic for the environment than other types of rechargeable batteries.
