Recharge Alkaline Batteries

recharge Alkaline batteries geek-prepperI recently discovered a battery charger that not only charges rechargeable batteries, but allows you to recharge Alkaline batteries too!

Recharge Alkaline Batteries

When I was a young boy, I had a friend who’s father was an electrical genius. He was always creating breadboard projects. One such project was a charger that charged dead batteries.

In my adult life I had pretty much relegated that memory to voodoo and the tricks that the brain can play on itself, but recently that all changed!

Not too long ago I was surfing the web and saw that someone had mentioned, in passing, that they had read someones post about a battery charger that allowed them to charge their old Alkaline batteries.

This is how I stumbles across the Maximal Power FC999 Universal Rapid Charger. I read up on it and researched the charging of Alkaline batteries.

I read all the reviews on the Maximal Power FC999 Universal Rapid Charger, then looked at this big box of dead batteries, that were destined for a recycling center. I then decided that if this thing worked, I could break even rather quickly.

The Maximal Power FC999 Universal Rapid Charger, uses an 8 bit microprocessor that utilizes an advanced RISC architecture with integrated converter and multi-channel high speed input/output ports to intelligently monitor and actively controls the entire charging cycle of the batteries, in real time, to prevent overcharging. It also has built-In negative delta V cut-off function and short-circuit protection.

They claim that they can recharge an Alkaline battery to %75-90% of original capacity up to and beyond 30 times! MORE THAN 30 TIMES! This isn’t a guarantee, but a rule of thumb, mileage will vary.

When you insert a battery into this charger it can determine within a few seconds if it’s bad and will let you know.

Maximal Power FC999 Universal Rapid Charger charges the following battery types:

  • AA
  • AAA
  • C
  • D
  • N
  • 9V
  • Ni-MH (Nickel Metal Hydride)
  • Ni-CD (Nickel Cadmium)
  • RAM (Rechargeable Alkaline Manganese)
  • Alkaline (previously Non-Rechargeable) batteries

The Maximal Power FC999 Universal Rapid Charger arrived yesterday and I’ve been charging my box o’ dead batteries. I have had 2 “bad” detections so far, and there were a handful of batteries that didn’t pass my visual inspection, everything else is charging right up.

I wish I’d had known years ago, that the technology exists to recharge alkaline batteries. I already have a small solar setup for charging batteries, but adding this charger to the mix would open the door to batteries that most people would discard without a second thought. It’s recycling, therefore it’s good for the environment and smart prepping!

    CAUTION! I too had read that you could recharge Alkaline batteries and I did buy the Maximal FC999 from Amazon and set about recharging my coffee can of used Duracell AA and AAA batteries. Everything looked great, the battery meter I got said that batteries had recharged so I stored 40 to 50 recharged batteries in empty prescription bottles. I went to use some the other day and the batteries had leaked a clear sticky fluid – I don’t what it was. I would NOT use those batteries in any of my equipment and threw all the used – recharged batteries away. This is no reflection on the charger, I do plan on buying some good quality rechargeable batteries and using the charger for those.

    Because non-rechargeable Alkaline batteries are not intended to be recharged they are not built to take the internal pressures that can occur during the process. Some are built better than others but all can leak. The new rechargeable alkaline batteries, (RAM or Rechargeable Alkaline Manganese), are said to have been designed to take the internal pressures that can occur during recharging. Also, trying to recharge any alkaline that has been deeply discharged will give less than satisfactory results especially if it has seen several repeated deep discharges. Like most battery chemistry’s the less deeply discharged they are the more life can be pumped back into them. Many battery chemistry’s can see several times the rated number of charge/discharge cycles if they’re not too deeply discharged each time. Deep cycle lead acid batteries are a classic example of this and are known to last well past their normal life when used in applications that only discharge them by 20% or less each time before recharging. Internal temperature during recharging is extremely important also. For this reason charging current is kept low to lower the risk of thermal runaway and subsequent rupture. Some chargers may pulse the current with a duty cycle and current level known to maximize charging time without causing to much internal heat. I think the secret to recharging any alkaline battery is a slow (lower current), charge. Being in a hurry and force feeding an alkaline will only increase the likelihood they’ll rupture.
