How Do I Choose the Best 3.7V Battery?

Most people are not aware that batteries are among the most useful, practical, and necessary accessories we use every day. These items store energy and allow you to enjoy a comfortable, convenient, and modern lifestyle. Your phone has a battery. Your laptop has one. If you use digital cameras, flashlights, or remotes, they might have different types of batteries as well. Even modern electric cars are using rechargeable batteries which allow them to power down the road with speeds of up to 120 miles per hour or more. Now you get how important batteries are?

One of the main advantages of modern batteries is that they’re rechargeable. That means you can use them hundreds of times without having to go to a shop and buy new ones. You simply plug them into a battery charger, stick that into your power outlet, and in a few hours your batteries are brimming with electricity again. If you go camping for a weekend, you can actually recharge multiple batteries, take them with you, and use them for your digital camera or video recorder.

There are also different types of batteries available on the market and in this guide, we’re going to take a look at the 3.7V ones which are some of the most popular batteries out there.
Batteries are not expensive accessories, and that’s a good thing. You can find a good pair of 3.7V rechargeable batteries for around 15 or 20 dollars. In a similar fashion, more sophisticated batteries can cost up to 30 bucks or more, and these are usually designed for specific gadgets or come with features such as a protection circuit board.

During our research, we also found a plethora of cheap 3.7V batteries on the market, but we think that they don’t provide good value for your money. These batteries either have poor durability or take ages to recharge. Especially if you use your gadgets regularly (flashlights, cameras, etc.), it’s worth spending a couple bucks more to get a quality, reliable item.
Believe it or not, today's 3.7V batteries also come with various features. Don’t make impulse purchases; read on and find out exactly what to look for when buying rechargeable 3.7V batteries.
  • Type - some batteries are specifically designed to work with certain camera models such as Nikon Coolpix cameras. Other batteries are universal and can be used for powering remotes, regular cameras, or flashlights.
  • Pieces - certain brands offer you more than just 2 batteries in the package; they might include up to 4. Obviously, that's better value for your money.
  • Accessories - in some cases, you have the option to buy the batteries with or without a charger. If you already have a device to charge your batteries, this is where you can save money and go just for the replaceable batteries.
  • mAh figure - the mAh stands for mili-Amper per hour, which is basically a way of measuring the capacity of a battery. This is similar to your cellphone battery's mAh number and the higher it is, the more power the battery can store. As a result, you’ll be able to use these rechargeable batteries for a longer period.
Construction and Design
Most 3.7V rechargeable batteries are based on the Lithium Ion technology, which gives them a long lifespan and enhanced durability. Certain batteries can even be used up to 1000 times! In other words, if you’re recharging them daily, you’ll be able to use these batteries for nearly 3 years.

Today's batteries are also designed to maintain approximately 3 quarters of their full capacity if they haven’t been used for a whole year. Basically, if you don’t use these batteries for 12 months, when you use them again you’ll still be able to enjoy 75% of their original capacity. In a similar fashion, some higher-end batteries are designed with a protection circuit, which prevents dangerous events such as small explosions or even fires.
Performance and Ease of Use
When it comes to performance, 3.7V rechargeable batteries can be used just as regular batteries are. For example, they are useful for powering digital cameras, remotes, flashlights, 2-way radios, walkie talkies, and even certain e-cigarettes. Obviously, it’s wise to check the label of the battery package to make sure they’re compatible with the types of gadgets you have.
