Battery Regenerator

New Life for Old Alkaline

Most of us have a stash of old alkaline batteries just waiting to be recycled or, even worse, headed for a landfill. It's time to rethink and recharge.

Lou Lentine, founder of Viatek, told us about a way to bring old alkaline batteries back to life, safely and without overheating or short-circuiting the cells. Lou explains that an alkaline battery can be renewed by cleaning the cells. The renewing process doesn’t add anything to the batteries, but it works to improve the internal structure of the cell so you can keep
using it, over and over again.

His smart charger is called the Renu-It Disposable Battery Regenerator. It can regenerate not only alkaline batteries but also nickel-cadmium (NiCd) and nickel-metal hydride (NiMH) cells. The Deluxe model can handle five sizes (AA, AAA, C, D and 9-volt).

It’s a simple, convenient solution that’s easy on the environment and easy on our wallets.

    We are so excited to share this product on the Daily Grommet. When we got the call stating our product would be featured, we were thrilled. Renu-it has been a great success for us. We are a very green company that is constantly looking for ways to help the environment and save money. Renu-it is a very good item that everyone will love. The product uses an advanced technology that will regenerate your batteries and save you money. The technology was actually first patented by the great Thomas Edison. You know the guy who developed the Light Bulb. He learned that a battery could actually be regenerated by cleaning the cells of the battery. We incorporated this technology in Renu it. Love to hear any questions or comments. Thanks again Daily Grommet. Lou Lentine. Inventor - Founder of Viatek.

    @Steve K: We have had our basic product approved by United Laboratories for safety. It uses the same principle. Our professional item uses a United Laboratories approved adapter for safety. Since launching we have sold over 250,000 pieces worldwide and the product is still considered new. With great sites like Daily Grommet and more, we hope more people learn about this wonderful technology. Here are a few testimonials. We have over 200 written reviews from users. TESTIMONIAL: The Renu battery regenerator is wonderful.It has recharged all of my so called Dead batteries that I refused to throw away in the past. I would always try to reuse these very weak or dead batteries on wall clocks and other one battery items, until it proved to me that it's really dead. Thank you to whoever thought of this great product and most of all... TESTIMONIAL:This thing has already paid for itself. With a ten year old son, the batteries are always in demand. The first day we got it we charged enough batteries for all his games and the controllers for his xbox. This is one of the best items we have bought. I highly recommend this to everyone who wants to save money. TESTIMONIAL:We purchased this item in hopes of being able to save money on batteries with the holidays fast approaching. We were pleasently surprised to find it WORKS!! - We have recharged Triple A's, Double A's, C's D's and 9 volts and have been able to reuse them without problem. This was a great investment. We have suggested this item to several people

    @Lou Lentine: Lou, with all due respect, SteveK has a legitimate question which has not been answered: "So what independent lab/s has/have tested this and approve of its reliability?" He did not mean the UL Lab registration (which every electrical product sold in the U.S. must have), he meant tests of reliability.

    You mention Thomas Edison who died in 1931

    You say "The technology was actually first patented by the great Thomas Edison.". Do you have a patent number on Edison's invention?

    You also say that a battery can be "regenerated by cleaning the cells of the battery". Are all batteries able to have their cells 'cleaned' or only the zinc-carbon batteries that existed during Edison's time which were invented in 1876. I ask this because today's popular alkaline battery was not invented until the 1950's and since Edison died in 1931...we are confused.

    Hope to hear from you soon with some answers...thanks for understanding.

    @VIctor K: I will let Lou speak to any formal testing, but we've been testing it for a month and a half and have been pleased with its performance. The batteries this unit regenerates are today's batteries; specifically Alkaline, NiCd and NiMH.

    This is great, even though we try to use rechargable batteries, Alkaline batteries are included with so many items that we end up with plenty of them as well. It sounds like this will give new life to both types.

    I have a few questions. How durable is this machine? Can it be used constantly? What would be its life expectancy if used constantly. I think this would make a wonderful project/small business for my kids. They could collect used batteries from neighbors and offer to recharge them. Also, regarding the charged batteries will they still perform well in gaming systems or will they lose their charge too quickly?

  • Anthony

    @Jess: I used this during testing for about a month and a half of charging various batteries from work (including from the container that Kate is holding in the video) as well as from home, changing them out every day. Which is far more frequently than most people will (hopefully) be using it.

    Additionally. I've used the re-charged batteries in all kinds of remotes, mice, keyboards, digital cameras, and wireless Xbox and Wii controllers, anything I or my nieces and nephews had that takes regular batteries and it didn't feel like they lost their charge any quicker than fresh batteries.

    The machine is very durable. It has automatic shutoff when batteries are charged so can be used constantly. Life expectancy is years. It has a 1 year warranty. Yes, they will still perform well in gaming systems. My kids use it for the Wii and Xbox controls. Also great for toys, remotes, smoke detectors and other electronics. The battery business idea is a good one. I learned of this technology over 5 years ago. I received a call from a gentleman from the UK. He told me that he had a business where he collected batteries and regenerated them. Then resold them. I was amazed. I flew to London and rented a car for a long 4 hour drive to his warehouse. He had rows and rows of tables where he had devices setup to regenerate. Once he regenerated, he repackaged and sold the recycled batteries to the local stores. He had a great business. I asked him if we could take this technology and create a product for the home. After a few years of development we created Renu-It.

    Great, fantastic. That'll really stick to the battery manufacturers. I'll save a bundle by recharging and reusing all those nasty, polluting, batteries that are cluttering up the kitchen drawer. Except, when the batteries are maxed out on re-charges I'll need to buy more batteries, and I'll still be stuck with the same issue - a drawer full of what is still hazardous waste that still needs proper disposal.

  • Michelle
    1/10/2011 3:13 PM

    @llkoolk: You make a valid point. I'm choosing to try to reduce waste of any kind as much as possible and that includes buying and using only rechargeable batteries, or using non-battery operated items where possible. However, for those disposable batteries that I already own, this is a good way to reuse them over and over before recycling them in the proper way.

    Also, I work for a child care center that for some unknown reason refuses to purchase reusable batteries and chargers for its baby swings and vibrating baby seats. We go through many D batteries in a month... if I purchase this product for my own home use, I'm hoping I can bring those depleted batteries home with me and recharge them. Once the center manager sees the financial and environmental benefits, perhaps she'll change her outlook. I can't change the world, but I can make small changes in my own little world and hopefully be an example to others.

    @Michelle: @llkoolk: Something else to keep in mind, those rechargeable batteries have a finite lifespan as well. You can only recharge them so many times for they have to be disposed of in a safe manner as well. No matter what technology you choose, rechargeable or not, they eventually will expire. This grommet lets you re-use batteries you already have and save money.

    Sounds like a good product. I have dozens of NiMH and NiCAD batteries that have lost their charge, no matter how long I recharge them. The NiCADs are over 10 years old and NiMH about 2 years old. Will this product restore back to holding the good charge they had when I first bought them? I'm thinking of what I was told about my defunct 2 year old laptop battery. That once "they go" for so long, they can't be reconditioned and buying another new is only option. (If what they say isn't correct, then how about a reconditioner for laptop batteries, too?)

    Does the 'Renu-It Battery Regenerator' have a warning that (especially for alkaline) batteries 'may leak acid'? Will it 're-new' a completely dead alkaline battery?

    I have a couple of 'recharger's', for alkaline & NiCad. About 5% of the alkaline will leak acid - usually after charging, and re-installing; which of course makes a mess and sometimes ruins the item that it was installed in. Has anyone had acid leaks from batteries 'renu-d in the regenerator'?

  • Katherine

    1/17/2011 1:24 AM

    @Stan: Great questions. I have forwarded them on to Lou who can give us the best explanation.

  • Lou
    Lou – Special Guest
    1/17/2011 3:02 PM

    @Stan: It will only leak acid if the battery is already leaking or damaged. We recommend to inspect battery visually before putting in device. It will renew a completely dead Alkaline battery. This unit was designed for alkaline batteries so leakage isn't a problem.

  • Mary
    1/20/2011 11:13 AM

    @Lou Lentine: If the battery does not show signs of leakage and does leak will it ruin the machine? I did not see a answer to this. My experience is that if it is going to happen to anyone it will happen to me and most always does so I have to know.

  • Lou

    @Mary: We recommend not to use if there has been a leak. The screen on the Renu It will display whether the battery is bad and should not be charged (reads: BAD) even if there aren’t any visible signs of leakage. The instructions state to remove the battery once the screen reads OK. We have seen batteries leak when a customer left the battery in for instance overnight and didn't follow the charging time instructions. This would result in a loss of warranty.

  • Mark
    5/19/2011 3:52 PM

    @Stan: I have noticed that about 1/4 of my batteries are bad, so I didn't recharge them. Of the other batteries I did recharge and then set aside for future use, I have found several that leaked acid after a while. I am also noticing that some batteries that were charged a month ago do not have any charge anymore. I also had to send my unit back because of a crack in the 9V port causing me to not be able to recharge that size anymore. Now that I am mentioning it, I have not received confirmation that they have received the unit, even after an e-mail query. It has been close to 2 months. Maybe someone from the company can get back to me.

    I received my Renu-It and see it takes up to 5 hrs to recharge AA alkalines. Does this unit use much energy and what other household appliance is it equivalent to in terms of energy usage? We have been "smart metered" so very conscious of our energy usage. tx

  • Ann
    1/18/2011 6:39 PM

    @Katherine Klinger:

    A new automated way of tracking energy usage vs the old way of having someone come out to read your meter. You can track your usage online also.

    @Ann: The Renu It puts out very little energy, although it is recommended that you unplug the unit from the wall when not in use.

    Input: 100-240V

    Output: 12V

    I charged 5 AA alkaline batteries successfully yesterday and recharging time on each battery varied from 90 min to the full 5 hours. One usage that was not highlighted was that a good battery is noted by a green OK button on the unit- so I was going to unknowingly recycle a perfectly good battery before this unit arrived. Also a suggestion to Lou, you may consider sending a unit to the Exploratorium I don't know if they are aware of this technology but it's right up their alley in terms of educating the public.

    I have been testing this very carefully on alkaline batteries, using a professional voltmeter and so on. It really works! (If you have a battery that is totally and utterly dead, it can't bring it back to life, but that's hardly surprising, and this is unlikely to happen in practice.) Wow!
