Best Rechargeable AA Batteries 2019 review

  • Jun 12th 2019

Using rechargeable batteries is a great way to save both money and do the environment a favor. Most of us cannot be bothered with the inherent hassle of charging the batteries or even to remember to charge them. So we instead wind up with discharged batteries or rechargeable batteries that are not working properly due to poor quality. The usability of rechargeable AA batteries skyrockets with the use of one simple trick: invest in two sets of high-quality rechargeable AA batteries and a battery charger with overcharge protection. When one set is discharged, put them in the charger and leave them there until the other set is depleted, rinse and repeat.

Which are the best rechargeable AA batteries?

In this rechargeable batteries review, we will take a look at the best rechargeable AA batteries of 2019. We will also review our pick for the best rechargeable AA batteries with charger included for those of you that are looking for an all-in-one solution. The battery market is flooded with all kinds of brands, types and makes and it can be hard to know which to buy. We will try help guide you in your choice for your next rechargeable AA battery purchase by discussing the pros and cons of the most prominent brands on the market. We will also set up a checklist of things to look for when trying to determine the actual quality of a rechargeable battery.

Most of us have at some time in the past bought rechargeable batteries just to be disappointed in how fast they drain when using them and how fast their capacity degrades after only a few recharges. In the past, the most common rechargeable battery was the Alkaline battery but now the NiMH (Nickel Metal Hydride) is the most common. This is for a reason since the alkaline battery type still has these problems with very few recharge cycles and fast capacity drain. NiMH batteries, on the other hand, can often be recharged up to 1000 times and are able to hold most of their charge even if left unused for extended periods of time.

How to determine the quality of rechargeable batteries

We will list the most important properties of a rechargeable battery, be it AA, AAA or even a C or D size battery. We will also explain in what way those properties matters so that you can easier determine what is the most important for your use case.

Capacity - This tells how much charge the AA battery can hold and in other words how long it can power your device. You want your batteries to have as great capacity as possible. It is meassuerd in Watt Hours or as it is most often marked: milli Watt hours (mWh).

Idle drain - Batteries lose charge over time even when not used. You want the drain to be as small as possible or if the also common term charge maintained is used you want that to be as high as possible. Keeping a charge of at least 70% after one year is something all AA batteries in this review can manage.

Recharge cycles - This indicates how many times you can recharge the battery before it needs to be discarded and replaced. You want the battery to have as many recharge cycles as possible, since this is the big money saving part of being able to recharge.

Pre-charge - Some rechargable batteries comes already charged when you buy them. The amount of charge might var quite a bit so be sure to check how much it is pre-charged. A popular thing that several manufactuers have started with is to use clean solar energy to apply the pre-charge. If you are consious about the environment this is something you should keep an eye out for.
