10 Best Rechargeable aa Batteries: Reviews and Buying Guide

Do you want to know which are the best AA rechargeable batteries for the quality price for your photographic equipment in 2019? We already saw an excellent option as rechargeable pillar charger, and today we are going to recommend which are the best rechargeable batteries you can find for the quality price for your flash or digital camera.

We have a few doubts. Is it better to buy batteries from well-known brands such as Sony, Energizer, Varta, Duracell, Panasonic Eneloop or riskless well-known brands? What rechargeable batteries last longer? How many load cycles? Ni-MH? Capacity in mAh? Where do you buy at the best price? We have it clear both for AAA and AA batteries: better a known brand, but we will surprise you.

Having said that, we also recommend buying the Technoline BC 700 charger to keep the batteries in good condition or to revive them and optimize their operation.

What we should consider buying good rechargeable batteries for a flash or a camera?

Some considerations for buying rechargeable batteries for a flash or digital cameras:

  • We will need an extra boost of capacity, is better to buy rechargeable batteries of 2500mAh compared to 2000mAh.
  • This increase in capacity makes them more expensive but the load lasts much longer
  • Its life cycle is much lower, going from about 1000 cycles to about 500 cycles.
  • We sacrificed useful life to achieve greater power and time of use between loads
  • You can save them unused for several years and then recover their capacity to 100%
  • The useful life using them constantly is about 3-5 years (they would be between 50% -60% capacity)
  • The recycling time of the flash is reduced with this type of batteries with more capacity.
  • They resist the lower temperatures better
  • The composition of the battery: Ni-MH

 What is the Best Battery Marking?

The market is full of brands but many of dubious quality that exaggerates capacity or can even be dangerous. Most are little known Chinese, although there are also brands of Asian origin of very good quality. In lanternas10 we have selected 8 brands including the best in the market and those with the best value for money.

When you constantly need batteries it is better that you always choose to buy the rechargeable batteries, the conventional batteries cause great expenses of money and that is why they have been falling behind, in addition, they are also much more polluting because they are a constant waste. Without a doubt, rechargeable batteries will always be the best in many aspects.

How often should the standard NiMH batteries be charged?

Ideally, these batteries should be charged before each use if they have been out of the charger for days or longer. If they are not used regularly, they should continue to be collected at least every thirty days. Sitting unloaded for long periods of time is actually detrimental to the NiMH. The more you use them and then charge them, the better the performance of the batteries.

What is a smart charger?

Intelligent chargers use microprocessor circuits to monitor certain battery parameters. These include temperature, voltage, and state of charge. These chargers use this information to determine when a battery has reached its charging capacity and the charge must end.

What is a trickle charge?

The trickle charge is a low-speed charge that is used to replenish the capacity of the lost battery by self-discharge.

What is self-discharge?

Self-discharge is a phenomenon in batteries where internal chemical reactions can reduce the stored charge of the battery, even without a connection between electrodes. It is known that this phenomenon reduces the useful life of the batteries and can cause them to be charged below their full capacity on the first use.

Best Selling Rechargeable Batteries

We use batteries for a wide range of appliances and electronic devices, from essential tools and accessories to portable media players and digital devices. Given the dependence we have on batteries at this time, it is really surprising that we continue to depend on buying batteries from time to time just to keep our devices and accessories, sometimes essential, running daily.

With this in mind, let’s delve into what the market has to offer in terms of rechargeable batteries and what is best to look for when buying any. Keep in mind that although they are more efficient than older versions, rechargeable batteries may differ from one another in terms of their construction. After taking a closer look at everything the market has to offer at this time, we have put together a list of the ten best rechargeable batteries money can buy for you to see.

Guide: What portable rechargeable batteries to buy

Perhaps surprisingly, the first rechargeable batteries were developed in 1859 by a French doctor named Gaston Planté (2). Planté’s first model was based on lead acid, a system that is still in use today but has been improved, today’s batteries have drastically improved storage capacity, the ability to be recharged many times, and will retain a charge for months or years of non-use. Sometimes it may be more convenient to carry a portable charger instead of spare batteries.

Choosing the right set of rechargeable batteries is not too complicated. We have prepared this Buyer’s Guide to focus on several features that will help you make your decision.

Storage capacity

The first factor to consider when buying rechargeable batteries is the number of milliamp-hours (mAh) that each battery contains. It is important to know that milliamperes-hours do not translate directly into hours of charge since milliamperes-hours and ampere-hours are units of electric charge and are not always direct indicators of how long a battery will last (3).

The duration of a specific battery depends both on its total storage capacity and on the amount of charge consumed by the device it feeds. In general, however, a 3000 mAh battery is designed to last three times longer than a 1000 mAh battery (4).

Recharge capacity

Over time, even rechargeable batteries will lose their charge and recharge capacity. Although they will last much longer than disposable alkaline batteries, it is important to consider how many times a rechargeable battery can be charged efficiently before it begins to operate below its optimum capacity.

Many of the rechargeable batteries mentioned above can be recharged anywhere from a couple of hundred times to over 2,000 times and still maintain their effectiveness. This is a big difference that can mean that some rechargeable batteries last longer than others.

For example, a battery that offers an average of 10 hours and can be recharged more than 2,000 times will provide more than 20,000 hours of charging. In comparison, a battery with a similar lifespan, but that can only be recharged 500 times, only offers a total of 5,000 hours of charging.

Useful life

Many rechargeable batteries are available in packs of 4, 8, 12, 16, 20, 24, and so on. However, because rechargeable batteries are different from traditional disposable batteries, more is not necessarily better.

Consider how often you change traditional batteries in the devices you use most often. It will probably change the batteries much less often as it becomes rechargeable. For this reason, it is important to consider the useful life of rechargeable batteries.

Many batteries suffer a phenomenon known as “self-discharge”. This means that they will lose their charge over time, even if it is not used. Rechargeable batteries tend to discharge much faster than alkaline batteries (5). This means that, if they have been sitting for a few years, they will still be rechargeable, but they may not hold a full charge for immediate use.
