How To Stop Your Batteries’ Drainage Without Breaking the Bank

If you are a regular reader of Lingua Franca, you already know that I like to take pictures with a P&S Canon PowerShot A720 IS.  This small camera uses two rechargeable AA batteries.  Over the years I’ve had problems acquiring high quality batteries, and those that are in the market, are too expensive.  Many times I had to use the normal alkaline Duracell Ultra Power batteries to stop the financial hemorrhage.  They are able to hold their charge pretty good, but they can not be recharged.  This implies frequent trips to the shop to replenish the stock.  I also use a small Sony radio to listen to the news during the evenings.  It also uses Duracell AA batteries.  My wife has a similar radio with same battery requirements.  This means that we deplete a generous amount of greenbacks to keep our devices alive.  Something had to be done.  We have a tight budget and every single dollar and cent counts.

Serendipitously, I happened into an ad on television of a battery recharger for disposable (AAA, AA and 9 volt) alkaline and rechargeable batteries (e.g., Nicad, Ni MH, 9 volt).  I immediately jotted the name of the product and the phone number of the company selling the device in Panama.  The Mighty Charger, as the product is called, is marketed by TV Offer in Panama at a price of $49.95 plus a sales (ITBMS) tax of 7 percent.  I investigated elsewhere bought it at Amazon for $24.99 FOB Miami, plus a transportation charge of  $11.98 bundled with eight (8) Panasonic Eneloop rechargeable batteries.  I paid $24.72 for the Panasonic rechargeable batteries. This should take care of my battery drainage problems and calm my exhausted pockets for many years to come.

I.  Mighty Charger

This is how the device does its job.  Chemical reactions within the battery cause electrons to be stripped away from the carbon negative terminal to its positive one, if allowed.  As a battery is used, the cell gets “disorganized” as electrons get confused trying to make their way to the positive terminal.  The Mighty Chargerreorganizes” the internal structure of the battery cell allowing it to be used multiple times.

BTW, the Mighty Charger is manufactured in China—as expected.

The device will not charge corroded or leaking batteries and won’t charge lithium batteries.  The Mighty Charger will recharge the following type of batteries:

  • Ni-Cad:  Battery Type AAA, capacity 400 mAh, charge time 4 hours; Battery Type AA, capacity 800 mAh, charge time 8 hours.
  • Ni-MH:  Battery Type AAA, capacity 700 mAh, charge time 6 hours; Battery Type AA, capacity 1300 mAh, charge time 10 hours.
  • Alkaline:  Battery Type AAA, capacity 1.5 volts, charge time 2 hours; Battery Type AA, capacity 1.5 volts, charge time 3 hours; 9 volt block, charge time 6 hours.

II.  Panasonic Eneloop Rechargeable Batteries

These remarkable rechargeable batteries will keep up to seventy percent of charge after five years of use.  They will also recharge up to 2,100 times.  Isn’t this amazing?

The batteries arrived pre-charged by the factory with solar energy.  Made in Japan and not in China, for a change.

When you are a retiree living on a shoestring budget, you have to look under the rocks looking for ways to squeeze more juice out of your gaunt pension check.  If you’re like me, you know what I’m talking about.  Good Day.

  1. How interesting that it charges disposable batteries, never heard of that before. I have a rechargeable battery unit that I use but it doesn’t get the batteries to charge for very long and I’m constantly popping them back into the charger. On vacation I decided to just bring regular energizer batteries and they lasted almost the entire 17 days. You’ll have to let us know how this works out for you, Omar. Have a great day!

  2. Morning Barbara:

    I had two AAA rechargeable Panasonic batteries completely dead for over four months and two Duracell Ultra Power alcaline batteries also without power for over a year.

    The AAA batteries were totally recharged in about three hours and the AA alcaline batteries were recharged after about ten hours. Now they are working just fine. This means that I will not buy any more batteries for a very long, long time.

    I fully recommend this product for those who are frequently buying alcaline or Ni MH batteries.

    Enjoy the rest of the day. 🙂


  3. Hola Omar,
    I have a friend who uses solar panels to recharge all the batteries for his cordless power tools in his shop. I’m going there this weekend to see his setup and build my own. Panama is a perfect place for solar applications like this and the savings will add up over a year.

    1. Hola Jim and Nena:

      I’ve head about solar panels used to charge cellphones, but not batteries. Sounds like a good idea for this country with an abundance of sunshine all year round.

      As the saying goes, “a penny saved is a penny earned”.
