Best Rechargeable Batteries

Best Rechargeable Batteries

In an age where technology is more advanced, and people are more aware than ever of the impact that we are having on the environment, it is astonishing that more people are not using rechargeable batteries. Not only are they more efficient, and considerably more economical than a regular battery, but they cut back on an incredible amount of waste, helping each one of us to do our part in reducing the population’s carbon footprint. The benefits of rechargeable batteries do not end there however.

Environmental Impact

Filled to the brim with chemicals, batteries are some of the very worst things that we throw out on a regular basis. In fact, it is estimated that rechargeable batteries have up to 32 times less impact on the environment than their disposable counterparts. This includes their impact on non-renewable natural energy sources, waste, air pollution, air acidification, water pollution, and global warming. Really, if for no other reason, the environmental impact that disposable batteries has should be reason enough to make the switch to rechargeable.

Good Economy

Not to mention, there is an obvious economical benefit to using rechargeable batteries. And not only do you save money on buying batteries every week, but rechargeable batteries are significantly more efficient than disposable batteries. This can make a world of difference when it comes to powering energy-sucking electronic devices. Rechargeable batteries are estimated to last up to five times longer than disposable batteries.

Emergency Storage

Of course, most preppers are already aware of the all of the widespread benefits of rechargeable batteries. And preppers would add one more – they are a far more useful as additions to a survival kit than a boatload of disposable batteries. They are an essential part of anyone’s food storage. And what’s more, you can use them in the meantime, without worrying about using up your emergency storage.

The Best Rechargeable Batteries

So then, when it comes to buying your rechargeable batteries you want to make sure that you make the right decision, and they will be in your possession for a long time.

Sanyo, Eneloop

Sanyo’s Eneloop is generally considered to be the best, most efficient rechargeable battery on the market. At an affordable $12 for four AA batteries, they are much more cost-effective than most other options, both disposable and rechargeable.


Energizer offers a number of rechargeable options, all of which have received mixed reviews, but they do represent a cost-effective, easy solution.


Energizer’s main competitor, Duracell, also offers a number of rechargeable batteries, but it is Duracell who can lay claim to the better reviews and overall better products. Neither option quite matches up to the Eneloop however.

  1. I totally agree that rechargeable batteries are much more economical than disposable. However, rechargeable batteries have left me high and dry many times. You can’t use them in a go bag as they will be down when you most need them. Lithium Ion are the ONLY way to go in something that will sit for months/years without being used and still have a USEABLE charge. Today, alkaline batteries say they have a ten year shelf life. I don’t know of ANY rechargeable that will have a useable charge left after ten years.

    Just an observation: Duracell Batteries are MUCH less likely to leak than energizer or other brands. I have had only one leak with a Duracell. EVERY single Energizer I have used has leaked.

    • Good points TexasScout.

      I personally have started buying Lithium Ion batteries for my “Go Bags” and use a combination of rechargeable and alkaline at home.

      Appreciate the comments.


  2. I too have struggled with rechargeable batteries. The downside to them is the voltage ratings. Most alkaline or Lithium batteries are rated at 1.5v and usually are closer to 1.58 or so voltage. The rechargeable batteries are 1.2 volts making them barely useful for some flashlights. I probably have 20 or more of these that I have used in various places. So what this realistically means is that only lower voltage needs can these be used in. Some examples are some remote controls, flashlights, etc. So like many others, I try using them where I can and have to recharge them more often than I would like because of the lower voltage sustainability of the cells.

    Like Rourke stated, I have them for home use but my Go Bag is only packed with disposables.

  3. I cant comment on the Sanyo batteries, but I will support the duracells. The engergizers rechargables Ive had all wound up in the trash can lol. Im using alot of off brand CVS pharmacy rechargeable right now, and they are holding up great.
    On the subject though, but not flashlight batterys, our rechargeable we use in the military are all lithium ion now, with the occasional Lithium Polymer (LiPo) for certain applications. They do have a discharge rate, but battery technology has came along way in the past 20 years with regards to self-discharge and reliability. I honestly think you should have a mix of non-rechargables, and rechargables (with a portable solar charger or similiar device included) in your supply. Use the conventional batteries when you absolutly must, but use your rechargables for the majority of the time.

    If you do get LiPo batteries, heres a tip… Never discharge them completely in a device. They do get problematic if you completely discharge them under a load. Self discharge seems to be ok (ours at work come completely drained from the factory and they work fine after a charging cycle)
    Have a great day
