Mighty Charger Questions and Answers

Q. Does the Mighty Charger work with 220V?
A. No, the Mighty Charger works with 110V only.

 

Q. How long will it take to recharge 9 volt copper-top and will the Mighty Charger charge the full 9V?
A. The Mighty Charger takes several hours to charge. Keep in mind that the only legitimate use of an alkaline battery charger is to recharge the battery often and well before it gets down to less than two thirds of its capacity. Once you let the battery get below 50%, the benefits of recharging diminish quickly. If you try to re-charge when the battery has dropped to 80% or less of its capacity, it will not take a charge that lasts very long. Alkaline battery chargers cannot effectively bring a dead cell back to life. If you recharge frequently, your batteries will not usually leak. But if you try to recharge cells that are way down in capacity, they will likely leak. Never leave an alkaline cell you recharge in a device where it will remain unused for more than a couple weeks. But using the Mighty Charger this way, can keep a 9v alkaline cell going for weeks that would otherwise have lasted only several days.

 

Q. Can the Mighty Charger charge double AA batteries?
A. Yes, the Mighty Charger can charge AA’s and AAA’s.

 

Q. Will the Mighty Charger recharge standard alkaline batteries such as Energizer, Duracell, and Rayovac batteries?
A. Yes, the Mighty Charger will recharge standard alkaline batteries.

 

Q. Is the Mighty Charger able to recharge or regenerate non-rechargeable batteries?
A. Yes, the Mighty Charger is able to regenerate non-rechargeable batteries.

 

Q. Is the Mighty Charger safe and does it work on Energizer lithium batteries?
A. No, do not charge Energizer Ultimate Lithium or E2 Lithium batteries. You can use the Mighty Charger with both Alkaline and NiMH batteries. There is a warning on the back of the package stating: "DO NOT CHARGE LITHIUM BATTERIES."

 

Q. When I put in four rechargeable batteries to the Mighty Charger and plug it in, the lights flash green. Will they stop flashing when the batteries are fully charged?
A. Yes they will, if they are good rechargeable batteries. When fully charged it will become a solid green. Remove solid lit batteries right away. For alkaline batteries, if the battery is fully dead, don't bother trying to recharge them. It can’t bring them back to life. If you have a battery tester handy you can check alkaline batteries before charging them, if some life left it will give them charge.

 

Q. What battery sizes will the Mighty Charger charge?
A. AA, AAA, and 9 volt

 

Q. How do you tell the status when charging a 9v alkaline Battery?
A. If when you first attach the battery to the Mighty Charger, it does not light up, it is dead and cannot be recharged. If it lights up and goes off and on, it is recharging. When it is charged, there is a steady light.

 

Mighty Charger REVIEWS

The Mighty Charger is a gimmick. The Mighty Charger is a waste of money. If anyone tells you that you can recharge alkaline batteries with the Mighty Charger, take it with a grain of salt. The science (if out there) is way too complicated to fit into a cheap, light, plastic charger. If you try to charge a dead battery, the Mighty Charger will more than likely reject it. If the Mighty Charger does charge, the battery only supplies enough charge for just 10 minutes of use. If you read the manual of the Mighty Charger, it says to charge when the batteries are not fully dead. Here is how they trick you. If you do what the manual says, you have no way of telling how much run time is left on the battery. So when you charge it up and continue to run it, you are thinking the Mighty Charger gave you all the charge, when in fact you had it all along. This is how they deceive you into thinking the Mighty Charger works.

 

The Mighty Charger does recharge most alkaline batteries. However, a few of the prongs have completely failed, such that 2-3 of the AA battery terminals are completely unusable. Maybe, eventually, all will fail. If you're willing to check for leaks during charging, perhaps you'll have better luck.

 

The Mighty Charger does not charge the Blue Planet batteries. They got super hot. You will be able to re-charge regular batteries with the Mighty Charger. Over time, however, you will realize that the batteries you re-charged with the Mighty Charger were hit-or-miss. Some of them had enough juice to be used for a little while, though never as much as a fresh battery, but some of them only lasted a couple of days which is a real nuisance. Also, the re-charged batteries seem prone to leaking much quicker than fresh batteries. The consensus reached is that the re-charged batteries are too weak and unstable to be worth using.

 

The Mighty Charger works fine on many different kinds and sizes of batteries. Hard to read positive/negative icons, and the AAs and AAAs feel like they are going to break it when you put them in, but they haven't. Mighty Charger is well worth the purchase price. The Mighty Charger seemed to work fine with rechargeable batteries but unfortunately, a number of the regular alkaline batteries that were recharged with it subsequently leaked. The Mighty Charger is recommended only for rechargeable batteries.

 

The Mighty Charger didn't work well even after trying it with ten batteries. One of them leaked chemicals. The problem with the Mighty Charger is that none of the batteries were fully charged. The charging light was flashing green after 12 hours charging. Several batteries were measured 1.42V after charging, which is not bad but they lose charge quickly after a day even though they were not used, just sitting on the table. The Mighty Charger doesn’t charge any regular batteries. During charging the Mighty Charger makes some cracking noise. You wouldn’t want to leave it charging without seeing it.

 

The Mighty Charger works sometimes. The Mighty Charger costs $20 at a local store but is cheaper on Amazon. It charges rechargeable batteries just fine, but most people buying the Mighty Charger already have a charger that is capable of recharging rechargeable batteries. The selling point is that the Mighty Charger is capable of charging disposable batteries. The Mighty Charger package claims, 40 recharges of disposable batteries. About 25% of disposable batteries that were put in the Mighty Charger did nothing at all. You may not get a green light or a red light or anything.

 

The idea of the Mighty Charger is great. It’s just not possible to recharge every battery with the Mighty Charger and unfortunately it doesn’t perform as well as you think it will.

 

Mighty Charger Pros: The Mighty Charger works! Used the Mighty Charger with quite a few AAA and AA batteries in the office and once they get too weak to do the job they were thrown in a box for recycling. Brought one new Mighty Charger and started recharging batteries from the recycling box. Put one of the recharged batteries in a pager and the battery indicator shows full charge! Time will tell how long they last after being recharged.

 

Mighty Charger Cons: Can be tricky getting the batteries seated properly in the slots, especially AAA cells. The Mighty Charger can't recharge batteries that are completely dead. If the LED doesn't light up when the charger is plugged in you can't tell if it's because the battery is bad or if it just isn't seated properly. Try reseating several times before writing off battery.

 

There was a pop sound from the Mighty Charger and a bubbling liquid in one of the batteries. After unplugging the charger and carefully removing the batteries one of the bottom prongs was stuck down. Tried to gently pry it back in to position and it popped off entirely. Odd thing is that the piece that fell out wasn't in the same slot as the battery that burst.

 

The Mighty Charger would have got five stars, only if: 1) The Mighty Charger had a built-in battery tester to show you if the alkaline battery you were attempting to charge had any juice left, reducing the risk of explosion or leakage of toxic gas 2) The Mighty Charger was better constructed and came from a brand name battery maker. Mystery electronics often make me uncomfortable, as does this, even though it does work as advertised. Not sure if the Mighty Charger has undergone as rigorous testing as a device from a known brand. However, the Mighty Charger does do what it says, and it will recharge spent non-rechargeable alkaline batteries, which is great for the environment, even if you only recharge one more time. So, keep track of your charge cycles, and when the capacity starts to dive, dispose off the batteries.

 

Cheap batteries don't respond as well as premium batteries to recharging, so don't start with cheap batteries expecting them to perform like premium batteries by recharging them.

 

On the plus side, the Mighty Charger will independently charge 3-4 batteries at a time depending on whether you're charging a 9V battery or not. It also appears that you can charge different types of batteries at the same time: NiMh, Alkaline, AA, AAA, etc. However, it appears that the Mighty Charger cannot recharge a completely dead alkaline (non rechargeable battery). Perhaps, it can extend the life of a non rechargeable battery if you charge it before it's completely dead.

  1. I have heard people comment about battery exploding in the mighty charger.I have one and it is wonderful,it works great with nicad,ni mh,and ALKALINE if you notice i cap.alkaline because zinc batterys are different from alkaline they could explode.dont try to recharge batterys that say’s super heavy duty only alkaline.

  2. Item works to my satisfaction. The beauty is the integrated circuit knows how to “trickle” charge the alkalines. It is true you cannot charge the batteries to their new condition but it does charge them satifactory. Nuff said…

  3. I have been using AA and AAA nickel-metal-hydroxy batteries for years, but rechargeable 9-volt batteries are more difficult to find and are expensive, so I am forced to buy alkaline ones. I purchased a Mighty Charger battery charger at a CVS Store a few days ago for $21.99. It does take 10 to 12 hours to recharge both rechargeable and alkaline AA and AAA batteries, probably because it charges at a lower voltage than many other battery chargers in order to not cause leakage or explosions of alkaline batteries. 9-volt alkaline batteries charge in the Mighty Charger in less than an hour. On the other hand, my Duracell battery charger charges AA and AAA batteries in less than 2 hours but only works for nickel-metal-hydroxide batteries and does not charge 9-volt batteries. Now I can start collecting the alkaline batteries that other people throw away after they lose their charge, and try to recharge them. That will lower the cost of batteries for me to just a few pennies each to recharge, so the charger will pay for itself quickly. On the downside, the metal springs in the Mighty Charger that hold batteries in place while they charge could have been designed a little better, because a couple of AAA batteries popped out of the charger after I put them in and plugged the charger in, and I had to repeatedly try to put them back in from different angles before they finally stayed in place and started charging. Also, it would be a nice feature if the electrical prongs that fit into wall sockets on the Mighty Charger were designed to fold away as travel chargers for cell phones and some other battery chargers do, in order to make it easier to pack for travel. I do like the housing of the Mighty Charger, which is made of durable plastic that should stand up to years of use. But again, I would like to encourage the designer and manufacturer to work on the tolerances for the metal springs that hold AAA batteries in place. Overall, I would recommend the Mighty Charger to others.

  4. yes…it does work. I work in an entertainment showroom and I use it every night on an actors mic. It starts out with 3 bars showing on the indicator but quickly goes down to two bars after about 15 mins. It stays with 2 bars for about 70 mins. The actor turns his wireless transmitter off after the show and I turn it back on when i get in around 2pm. It’s usually on 1 bar by then. I pop it in the charger to charge up until 7pm and it’s back up to 3 bars. Very cool and saves the producer money. I would always have a brand new alcaline battery ready to go just in case. Not all batteries are created equal.
    Good Luck!

  5. This piece of equipment is a scam as alkaline batteries cannot be recharged with something that simple. Rechargeable batteries are different and the batteries are going to explode dumb shits.

    • How do you know? Have you bought and actually tried it? What was your personal experience? Very seriously thinking of trying this. Please help. Thanks.

    • You have no idea what you are talking about. I have been recharging non rechargeable batteries for years with standard battery chargers and none have exploded. I recall one started leaking and I just threw it away, but the rest recharged fine. If they don’t except a charge then just throw them away, since they are most likely shorted.

    • Everyone , first , I just bought one of these. I haven’t opened it yet. About 15-20 years ago (yes, you read that right) my aunt and uncle had a Buddy-L brand charger that could charge disposable alkaline batts, including C and D size. It worked great! With that said, alkaline batts could be recharged about 6-8 times before they would no longer hold a charge. Charging DID NOT cause any leaking/exploding(lol). If you listen to the garbage the batt mfg comps
      tell you, or rumors stemming from such, sure, you’ll probably freak out at the idea. Everyone relax. Alkaline can be recharged and no crazy stuff will happen in the process. I’m sure I’ll save a little money at least after I start using this gadget. If something does come up, I’ll let everyone know.

    • Have you tried it? We have and it works great. They do not leak or explode. We are saving a lot of money from having this charger. We have one in the house and one in the semi truck. I’m going to buy more to give as gifts this year.

    • I bought Mighty Charger from the As Seen On TV section at Walmart the other day because I am going through batteries like crazy for my Beats Studio Headphones. This device does work! It’s not perfect I must say.. but it does charge any battery AA, AAA, or 9 volt. Doesn’t make the batter have a charge as if they were when they was new but it does charge them to working potential! Whomever says it don’t work obviously hasn’t really used it.

        • Even if it’s not a full charge, it works great and the batteries will last a lot longer, saving you a lot of money.

          • Just got one of those chargers at CVS. does not have UL stamp ,has places for 4 bats plus 1 9V. 4 lights blink green and am waiting to check with multi meter. Will find out soon.
